What Is an Annotated Bibliography? | Examples & Format

Published on March 9, 2021 by Jack Caulfield . Revised on August 23, 2022.

An annotated bibliography is a list of source references that includes a short descriptive text (an annotation) for each source. It may be assigned as part of the research process for a paper , or as an individual assignment to gather and read relevant sources on a topic.

Scribbr’s free Citation Generator allows you to easily create and manage your annotated bibliography in APA or MLA style. To generate a perfectly formatted annotated bibliography, select the source type, fill out the relevant fields, and add your annotation.

Make sure your annotated bibliography is formatted according to the guidelines of the style guide you’re working with. Three common styles are covered below:

In APA Style , both the reference entry and the annotation should be double-spaced and left-aligned.

The reference entry itself should have a hanging indent . The annotation follows on the next line, and the whole annotation should be indented to match the hanging indent. The first line of any additional paragraphs should be indented an additional time.

In an MLA style annotated bibliography , the Works Cited entry and the annotation are both double-spaced and left-aligned.

The Works Cited entry has a hanging indent. The annotation itself is indented 1 inch (twice as far as the hanging indent). If there are two or more paragraphs in the annotation, the first line of each paragraph is indented an additional half-inch, but not if there is only one paragraph.

Chicago style

In a  Chicago style annotated bibliography , the bibliography entry itself should be single-spaced and feature a hanging indent.

The annotation should be indented, double-spaced, and left-aligned. The first line of any additional paragraphs should be indented an additional time.

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

For each source, start by writing (or generating ) a full reference entry that gives the author, title, date, and other information. The annotated bibliography format varies based on the citation style you’re using.

The annotations themselves are usually between 50 and 200 words in length, typically formatted as a single paragraph. This can vary depending on the word count of the assignment, the relative length and importance of different sources, and the number of sources you include.

Consider the instructions you’ve been given or consult your instructor to determine what kind of annotations they’re looking for:

• Descriptive annotations : When the assignment is just about gathering and summarizing information, focus on the key arguments and methods of each source.
• Evaluative annotations : When the assignment is about evaluating the sources , you should also assess the validity and effectiveness of these arguments and methods.
• Reflective annotations : When the assignment is part of a larger research process, you need to consider the relevance and usefulness of the sources to your own research.

These specific terms won’t necessarily be used. The important thing is to understand the purpose of your assignment and pick the approach that matches it best. Interactive examples of the different styles of annotation are shown below.

A descriptive annotation summarizes the approach and arguments of a source in an objective way, without attempting to assess their validity.

In this way, it resembles an abstract , but you should never just copy text from a source’s abstract, as this would be considered plagiarism . You’ll naturally cover similar ground, but you should also consider whether the abstract omits any important points from the full text.

The interactive example shown below describes an article about the relationship between business regulations and CO 2 emissions.

Rieger, A. (2019). Doing business and increasing emissions? An exploratory analysis of the impact of business regulation on CO 2 emissions. Human Ecology Review , 25 (1), 69–86. https://www.jstor.org/stable/26964340

An evaluative annotation also describes the content of a source, but it goes on to evaluate elements like the validity of the source’s arguments and the appropriateness of its methods .

For example, the following annotation describes, and evaluates the effectiveness of, a book about the history of Western philosophy.

Kenny, A. (2010). A new history of Western philosophy: In four parts . Oxford University Press.

Prevent plagiarism. Run a free check.

A reflective annotation is similar to an evaluative one, but it focuses on the source’s usefulness or relevance to your own research.

Reflective annotations are often required when the point is to gather sources for a future research project, or to assess how they were used in a project you already completed.

The annotation below assesses the usefulness of a particular article for the author’s own research in the field of media studies.

Manovich, Lev. (2009). The practice of everyday (media) life: From mass consumption to mass cultural production? Critical Inquiry , 35 (2), 319–331. https://www.jstor.org/stable/10.1086/596645

Manovich’s article assesses the shift from a consumption-based media culture (in which media content is produced by a small number of professionals and consumed by a mass audience) to a production-based media culture (in which this mass audience is just as active in producing content as in consuming it). He is skeptical of some of the claims made about this cultural shift; specifically, he argues that the shift towards user-made content must be regarded as more reliant upon commercial media production than it is typically acknowledged to be. However, he regards web 2.0 as an exciting ongoing development for art and media production, citing its innovation and unpredictability.

The article is outdated in certain ways (it dates from 2009, before the launch of Instagram, to give just one example). Nevertheless, its critical engagement with the possibilities opened up for media production by the growth of social media is valuable in a general sense, and its conceptualization of these changes frequently applies just as well to more current social media platforms as it does to Myspace. Conceptually, I intend to draw on this article in my own analysis of the social dynamics of Twitter and Instagram.

Before you can write your annotations, you’ll need to find sources . If the annotated bibliography is part of the research process for a paper, your sources will be those you consult and cite as you prepare the paper. Otherwise, your assignment and your choice of topic will guide you in what kind of sources to look for.

Make sure that you’ve clearly defined your topic , and then consider what keywords are relevant to it, including variants of the terms. Use these keywords to search databases (e.g., Google Scholar ), using Boolean operators to refine your search.

Sources can include journal articles, books, and other source types , depending on the scope of the assignment. Read the abstracts or blurbs of the sources you find to see whether they’re relevant, and try exploring their bibliographies to discover more. If a particular source keeps showing up, it’s probably important.

Once you’ve selected an appropriate range of sources, read through them, taking notes that you can use to build up your annotations. You may even prefer to write your annotations as you go, while each source is fresh in your mind.

An annotated bibliography is an assignment where you collect sources on a specific topic and write an annotation for each source. An annotation is a short text that describes and sometimes evaluates the source.

Any credible sources on your topic can be included in an annotated bibliography . The exact sources you cover will vary depending on the assignment, but you should usually focus on collecting journal articles and scholarly books . When in doubt, utilize the CRAAP test !

Each annotation in an annotated bibliography is usually between 50 and 200 words long. Longer annotations may be divided into paragraphs .

The content of the annotation varies according to your assignment. An annotation can be descriptive, meaning it just describes the source objectively; evaluative, meaning it assesses its usefulness; or reflective, meaning it explains how the source will be used in your own research .

A source annotation in an annotated bibliography fulfills a similar purpose to an abstract : they’re both intended to summarize the approach and key points of a source.

However, an annotation may also evaluate the source , discussing the validity and effectiveness of its arguments. Even if your annotation is purely descriptive , you may have a different perspective on the source from the author and highlight different key points.

You should never just copy text from the abstract for your annotation, as doing so constitutes plagiarism .

How to Prepare an Annotated Bibliography: The Annotated Bibliography

• The Annotated Bibliography
• Fair Use of this Guide

Explanation, Process, Directions, and Examples

What is an annotated bibliography.

An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited.

Annotations vs. Abstracts

Abstracts are the purely descriptive summaries often found at the beginning of scholarly journal articles or in periodical indexes. Annotations are descriptive and critical; they may describe the author's point of view, authority, or clarity and appropriateness of expression.

The Process

Creating an annotated bibliography calls for the application of a variety of intellectual skills: concise exposition, succinct analysis, and informed library research.

First, locate and record citations to books, periodicals, and documents that may contain useful information and ideas on your topic. Briefly examine and review the actual items. Then choose those works that provide a variety of perspectives on your topic.

Cite the book, article, or document using the appropriate style.

Write a concise annotation that summarizes the central theme and scope of the book or article. Include one or more sentences that (a) evaluate the authority or background of the author, (b) comment on the intended audience, (c) compare or contrast this work with another you have cited, or (d) explain how this work illuminates your bibliography topic.

Critically Appraising the Book, Article, or Document

For guidance in critically appraising and analyzing the sources for your bibliography, see How to Critically Analyze Information Sources . For information on the author's background and views, ask at the reference desk for help finding appropriate biographical reference materials and book review sources.

Choosing the Correct Citation Style

Check with your instructor to find out which style is preferred for your class. Online citation guides for both the Modern Language Association (MLA) and the American Psychological Association (APA) styles are linked from the Library's Citation Management page .

Sample Annotated Bibliography Entries

The following example uses APA style ( Publication Manual of the American Psychological Association , 7th edition, 2019) for the journal citation:

Waite, L., Goldschneider, F., & Witsberger, C. (1986). Nonfamily living and the erosion of traditional family orientations among young adults. American Sociological Review, 51 (4), 541-554. The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families. In contrast, an earlier study by Williams cited below shows no significant gender differences in sex role attitudes as a result of nonfamily living.

This example uses MLA style ( MLA Handbook , 9th edition, 2021) for the journal citation. For additional annotation guidance from MLA, see 5.132: Annotated Bibliographies .

Waite, Linda J., et al. "Nonfamily Living and the Erosion of Traditional Family Orientations Among Young Adults." American Sociological Review, vol. 51, no. 4, 1986, pp. 541-554. The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles.

How to Write an Annotated Bibliography - APA Style (7th Edition)

What is an annotation, how is an annotation different from an abstract, what is an annotated bibliography, types of annotated bibliographies, descriptive or informative, analytical or critical, to get started.

An annotation is more than just a brief summary of an article, book, website, or other type of publication. An annotation should give enough information to make a reader decide whether to read the complete work. In other words, if the reader were exploring the same topic as you, is this material useful and if so, why?

While an abstract also summarizes an article, book, website, or other type of publication, it is purely descriptive. Although annotations can be descriptive, they also include distinctive features about an item. Annotations can be evaluative and critical as we will see when we look at the two major types of annotations.

An annotated bibliography is an organized list of sources (like a reference list). It differs from a straightforward bibliography in that each reference is followed by a paragraph length annotation, usually 100–200 words in length.

Depending on the assignment, an annotated bibliography might have different purposes:

• Provide a literature review on a particular subject
• Help to formulate a thesis on a subject
• Demonstrate the research you have performed on a particular subject
• Provide examples of major sources of information available on a topic
• Describe items that other researchers may find of interest on a topic

There are two major types of annotated bibliographies:

A descriptive or informative annotated bibliography describes or summarizes a source as does an abstract; it describes why the source is useful for researching a particular topic or question and its distinctive features. In addition, it describes the author's main arguments and conclusions without evaluating what the author says or concludes.

For example:

McKinnon, A. (2019). Lessons learned in year one of business.  Journal of Legal Nurse Consulting ,  30 (4), 26–28. This article describes some of the difficulties many nurses experience when transitioning from nursing to a legal nurse consulting business. Pointing out issues of work-life balance, as well as the differences of working for someone else versus working for yourself, the author offers their personal experience as a learning tool. The process of becoming an entrepreneur is not often discussed in relation to nursing, and rarely delves into only the first year of starting a new business. Time management, maintaining an existing job, decision-making, and knowing yourself in order to market yourself are discussed with some detail. The author goes on to describe how important both the nursing professional community will be to a new business, and the importance of mentorship as both the mentee and mentor in individual success that can be found through professional connections. The article’s focus on practical advice for nurses seeking to start their own business does not detract from the advice about universal struggles of entrepreneurship makes this an article of interest to a wide-ranging audience.

An analytical or critical annotation not only summarizes the material, it analyzes what is being said. It examines the strengths and weaknesses of what is presented as well as describing the applicability of the author's conclusions to the research being conducted.

Analytical or critical annotations will most likely be required when writing for a college-level course.

McKinnon, A. (2019). Lessons learned in year one of business.  Journal of Legal Nurse Consulting ,  30 (4), 26–28. This article describes some of the difficulty many nurses experience when transitioning from nursing to a nurse consulting business. While the article focuses on issues of work-life balance, the differences of working for someone else versus working for yourself, marketing, and other business issues the author’s offer of only their personal experience is brief with few or no alternative solutions provided. There is no mention throughout the article of making use of other research about starting a new business and being successful. While relying on the anecdotal advice for their list of issues, the author does reference other business resources such as the Small Business Administration to help with business planning and professional organizations that can help with mentorships. The article is a good resource for those wanting to start their own legal nurse consulting business, a good first advice article even. However, entrepreneurs should also use more business research studies focused on starting a new business, with strategies against known or expected pitfalls and issues new businesses face, and for help on topics the author did not touch in this abbreviated list of lessons learned.

Now you are ready to begin writing your own annotated bibliography.

• Choose your sources - Before writing your annotated bibliography, you must choose your sources. This involves doing research much like for any other project. Locate records to materials that may apply to your topic.
• Review the items - Then review the actual items and choose those that provide a wide variety of perspectives on your topic. Article abstracts are helpful in this process.
• The purpose of the work
• A summary of its content
• Information about the author(s)
• For what type of audience the work is written
• Its relevance to the topic
• Any special or unique features about the material
• Research methodology
• The strengths, weaknesses or biases in the material

Annotated bibliographies may be arranged alphabetically or chronologically, check with your instructor to see what he or she prefers.

Please see the  APA Examples page  for more information on citing in APA style.

Annotated Bibliographies

What Is An Annotated Bibliography?

What is an annotated bibliography.

An annotated bibliography is a list of citations (references) to books, articles, and documents followed by a brief summary, analysis or evaluation, usually between 100-300 words, of the sources that are cited in the paper.  This summary provides a description of the contents of the source and may also include evaluative comments, such as the relevance, accuracy and quality of the source.  These summaries are known as annotations. 

• Annotated bibliographies are completed before a paper is written
• They can be stand-along assignments
• They can be used as a reference tool as a person works on their paper

Annotations vs. Abstracts

Abstracts are the descriptive summaries of article contents found at the beginning of scholarly journal articles that are written by the article author(s) or editor. Their purpose is to inform a reader about the topic, methodology, results and conclusion of the research of the article's author(s).  The summaries are provided so that a researcher can determine whether or not the article may have information of interest to them.  Abstracts do not serve an evaluative purpose.

Annotations found in bibliographies are evaluations of sources cited in a paper.  They describe a work, but also critique the source by examining the author’s point of view, the strengths and weakness of the research or article hypothesis or how well the author presented their research or findings.

How to write an annotated bibliography

The creation of an annotated bibliography is a three-step process. It starts with finding and evaluating sources for your paper. Next is choosing the type or category of annotation, then writing the annotation for each different source. The final step is to choose a citation style for the bibliography.

Types of Annotated Bibliographies

Types of Annotations

Annotations come in different types, the one to use depends on the instructor’s assignment.  Annotations can be descriptive, a summary, or an  evaluation or a combination of descriptive and evaluation.

Descriptive/Summarizing Annotations

There are two kinds of descriptive or summarizing annotations, informative or indicative, depending on what is most important for a reader to learn about a source.  Descriptive/summarizing annotations provide a brief overview or summary of the source. This can include a description of the contents and a statement of the main argument or position of the article as well as a summary of the main points.  It may also describe why the source would be useful for the paper’s topic or question. 

Indicative annotations provide a quick overview of the source, the kinds of questions/topics/issues or main points that are addressed by the source, but do not include information from the argument or position itself.

Informative annotations, like indicative annotations, provide a brief summary of the source.   In addition, an informative annotation identifies the hypothesis, results, and conclusions presented by the source.  When appropriate, they describe the author’s methodology or approach to the topic under discussion.  However, they do not provide information about the sources usefulness to the paper or contains analytical or critical information about the source’s quality. 

Evaluative Annotations (also known as critical or analytical)

Evaluative annotations go beyond just summarizing the source and listing out it’s key points, but also analyzes the content. It looks at the strengths and weaknesses of the article’s argument, the reliability of the presented information as well as any biases of the author. It talks about how the source may be useful to a particular field of study or the person’s research project.

Combination Annotations

Combination annotations “combine” aspects from indicative/informative and evaluative annotations and are the most common category of annotated bibliography.  Combination annotations include one to two sentences summarizing or describing content, in addition to one or more sentences providing an critical evaluation.

Writing Style for Annotations

Annotations typically follow three specific formats depending on how long they are.

• Phrases – Short phrases providing the information in a quick, concise manner.
• Sentences – Complete sentences with proper punctuation and grammar, but are short and concise.
• Paragraphs – Longer annotations break the information out into different paragraphs. This format is very effective for combination annotations.

To sum it up:

An annotation may include the following information:

• A brief summary or overview of the source content
• The source’s strengths and weaknesses in presenting the argument or position
• Its conclusions
• Why the source is relevant in to field of study of the paper
• Its relationships to other studies in the field
• An evaluation of the research methodology (if applicable)
• Information about the author’s background and potential biases
• Conclusions about the usefulness of the source for the paper

Critically Analyzing Articles

In order to write an annotation for a paper source, you need to first read and then critically analyze it:

• Try to identify the topic of the source -- what is it about and is it clearly stated.
• See if you can identify the purpose of the author(s) in doing the research or writing about the topic. Is it to survey and summarize research on a topic?  Is the author(s) presenting an argument based on previous research, or refuting previously published research?
• Identify the research methods used and try to identify whether they appear to be suitable or not for the stated purpose of the research.  
• Was the research reported in a consistent or clear manner?  Or, was the author's argument/position presented in a consistent or convincing manner? Did the author(s) fail to acknowledge and explain any limitations?
• Was the logic of the research/argument claims properly supported with convincing evidence/analysis/data? Did you spot any fallacies?
• Check whether the author(s) refers to other research and if similar studies have been done. 
• If illustrations or charts are used, are they effective in presenting information?
• Analyze the sources that were used by the author(s). Did the author(s) miss any important studies they should have considered?
• Your opinion of the source -- do you agree with or are convinced of the findings?  
• Your estimation of the source’s contribution to knowledge and its implications or applications to the field of study.

Formatting An Annotated Bibliography

How do I format my annotated bibliography?

An annotated bibliography entry consists of two components: the Citation and the Annotation.

The citation should be formatted in the bibliographic style that your instructor has requested for the paper. Some common citation styles include APA, MLA, and Chicago. For more information on citation styles, see Writing Guides, Style Manuals and the Publication Process in the Biological & Health Sciences .

Many databases (e.g., PubMed, Academic Search Premier, Library Search on library homepage, and Google Scholar) offer the option of creating your references in various citation styles. 

Look for the "cite" link -- see examples for the following resources:

APA does not have specific formatting rules for annotations, just for the citation and bibliography.

Maak, T. (2007). Responsible leadership, stakeholder engagement, and the emergence of social capital. Journal of Business Ethics, 74, 329-343.  https://doi.org/10.1007/s10551-007-9510-5

This article focuses on the role of social capital in responsible leadership. It looks at both the social networks that a leader builds within an organization, and the links that a leader creates with external stakeholders. Maak’s main aim with this article seems to be to persuade people of the importance of continued research into the abilities that a leader requires and how they can be acquired. The focus on the world of multinational business means that for readers outside this world many of the conclusions seem rather obvious (be part of the solution not part of the problem). In spite of this, the article provides useful background information on the topic of responsible leadership and definitions of social capital which are relevant to an analysis of a public servant.

An example of an Evaluative Annotation , MLA Style (10th ed), (sample from Columbia College, Vancouver, Canada )

MLA style requires double-spacing (not shown here) and paragraph indentations.

London, Herbert. “Five Myths of the Television Age.” Television Quarterly, vol. 10, no. 1, Mar. 1982, pp. 81-69.

     Herbert London, the Dean of Journalism at New York University and author of several books and articles, explains how television contradicts five commonly believed ideas. He uses specific examples of events seen on television, such as the assassination of John Kennedy, to illustrate his points. His examples have been selected to contradict such truisms as: “seeing is believing”; “a picture is worth a thousand words”; and “satisfaction is its own reward.” London uses logical arguments to support his ideas which are his personal opinion. He does not refer to any previous works on the topic. London’s style and vocabulary would make the article of interest to any reader. The article clearly illustrates London’s points, but does not explore their implications leaving the reader with many unanswered questions.

What is An Annotated Bibliography?

An annotated bibliography is a list of sources (books, articles, websites, etc.) with short paragraph about each source. An annotated bibliography is sometimes a useful step before drafting a research paper, or it can stand alone as an overview of the research available on a topic.

Each source in the annotated bibliography has a citation - the information a reader needs to find the original source, in a consistent format to make that easier. These consistent formats are called citation styles.  The most common citation styles are MLA (Modern Language Association) for humanities, and APA (American Psychological Association) for social sciences.

Annotations are about 4 to 6 sentences long (roughly 150 words), and address:

•     Main focus or purpose of the work
•     Usefulness or relevance to your research topic 
•     Special features of the work that were unique or helpful
•     Background and credibility of the author
•     Conclusions or observations reached by the author

Many scholarly articles start with an abstract, which is the author's summary of the article to help you decide whether you should read the entire article.  This abstract is not the same thing as an annotation.  The annotation needs to be in your own words, to explain the relevance of the source to your particular assignment or research question.

MLA 9th Annotated Bibliography Examples

Ontiveros, Randy J.  In the Spirit of a New People: The Cultural Politics of the Chicano Movement . New York UP, 2014.

This book analyzes the journalism, visual arts, theater, and novels of the Chicano movement from 1960 to the present as articulations of personal and collective values. Chapter 3 grounds the theater of El Teatro Campesino in the labor and immigrant organizing of the period, while Chapter 4 situates Sandra Cisneros’s novel  Caramelo  in the struggles of Chicana feminists to be heard in the traditional and nationalist elements of the Chicano movement. Ontiveros provides a powerful and illuminating historical context for the literary and political texts of the movement.

Journal article

Alvarez, Nadia, and Jack Mearns. “The Benefits of Writing and Performing in the Spoken Word Poetry Community.”  The Arts in Psychotherapy , vol. 41, no. 3, July 2014, pp. 263-268.  ScienceDirect ,  https://doi.org/10.1016/j.aip.2014.03.004 .

Spoken word poetry is distinctive because it is written to be performed out loud, in person, by the poet. The ten poets interviewed by these authors describe “a reciprocal relationship between the audience and the poet” created by that practice of performance. To build community, spoken word poets keep metaphor and diction relatively simple and accessible. Richness is instead built through fragmented stories that coalesce into emotional narratives about personal and community concerns.  This understanding of poets’ intentions illuminates their recorded performances.

The findings are limited by the small, nonrandom sample (all the participants were from the same community).

How to Write an Annotated Bibliography

Writing annotations.

• Introduction
• New RefWorks
• Formatting Citations
• Sample Annotated Bibliographies

An annotation is a brief note following each citation listed on an annotated bibliography.  The goal is to briefly summarize the source and/or explain why it is important for a topic.  They are typically a single concise paragraph, but might be longer if you are summarizing and evaluating.

Annotations can be written in a variety of different ways and it’s important to consider the style you are going to use.  Are you simply summarizing the sources, or evaluating them?  How does the source influence your understanding of the topic?  You can follow any style you want if you are writing for your own personal research process, but consult with your professor if this is an assignment for a class.

Annotation Styles

• Combined Informative/Evaluative Style - This style is recommended by the library as it combines all the styles to provide a more complete view of a source.  The annotation should explain the value of the source for the overall research topic by providing a summary combined with an analysis of the source.  

Aluedse, O. (2006). Bullying in schools: A form of child abuse in schools.  Educational Research Quarterly ,  30 (1), 37.

The author classifies bullying in schools as a “form of child abuse,” and goes well beyond the notion that schoolyard bullying is “just child’s play.” The article provides an in-depth definition of bullying, and explores the likelihood that school-aged bullies may also experience difficult lives as adults. The author discusses the modern prevalence of bullying in school systems, the effects of bullying, intervention strategies, and provides an extensive list of resources and references.

Statistics included provide an alarming realization that bullying is prevalent not only in the United States, but also worldwide. According to the author, “American schools harbor approximately 2.1 million bullies and 2.7 million victims.” The author references the National Association of School Psychologists and quotes, “Thus, one in seven children is a bully or a target of bullying.” A major point of emphasis centers around what has always been considered a “normal part of growing up” versus the levels of actual abuse reached in today’s society.

The author concludes with a section that addresses intervention strategies for school administrators, teachers, counselors, and school staff. The concept of school staff helping build students’ “social competence” is showcased as a prevalent means of preventing and reducing this growing social menace. Overall, the article is worthwhile for anyone interested in the subject matter, and provides a wealth of resources for researching this topic of growing concern.

(Renfrow & Teuton, 2008)

• Informative Style -  Similar to an abstract, this style focuses on the summarizing the source.  The annotation should identify the hypothesis, results, and conclusions presented by the source.

Plester, B., Wood, C, & Bell, V. (2008). Txt msg n school literacy: Does texting and knowledge of text abbreviations adversely affect children's literacy attainment? Literacy , 42(3), 137-144.

Reports on two studies that investigated the relationship between children's texting behavior, their knowledge of text abbreviations, and their school attainment in written language skills. In Study One, 11 to 12 year-old children reported their texting behavior and translated a standard English sentence into a text message and vice versa. In Study Two, children's performance on writing measures were examined more specifically, spelling proficiency was also assessed, and KS2 Writing scores were obtained. Positive correlations between spelling ability and performance on the translation exercise were found, and group-based comparisons based on the children's writing scores also showed that good writing attainment was associated with greater use of texting abbreviations (textisms), although the direction of this association is not clear. Overall, these findings suggest that children's knowledge of textisms is not associated with poor written language outcomes for children in this age range. 

(Beach et al., 2009)

• Evaluative Style - This style analyzes and critically evaluates the source.  The annotation should comment on the source's the strengths, weaknesses, and how it relates to the overall research topic.

Amott, T. (1993). Caught in the Crisis: Women in the U.S. Economy Today . New York: Monthly Review Press.

A very readable (140 pp) economic analysis and information book which I am currently considering as a required collateral assignment in Economics 201. Among its many strengths is a lucid connection of "The Crisis at Home" with the broader, macroeconomic crisis of the U.S. working class (which various other authors have described as the shrinking middle class or the crisis of de-industrialization).

(Papadantonakis, 1996)

• Indicative Style - This style of annotation identifies the main theme and lists the significant topics included in the source.  Usually no specific details are given beyond the topic list . 

Example: 

Gambell, T.J., & Hunter, D. M. (1999). Rethinking gender differences in literacy. Canadian Journal of Education , 24(1) 1-16.

Five explanations are offered for recently assessed gender differences in the literacy achievement of male and female students in Canada and other countries. The explanations revolve around evaluative bias, home socialization, role and societal expectations, male psychology, and equity policy.

Write an Annotated Bibliography

What is an annotated bibliography?

It is a list of citations for various books, articles, and other sources on a topic. 

An annotation is a short summary and/or critical evaluation of a source.

Annotated bibliographies answer the question: "What would be the most relevant, most useful, or most up-to-date sources for this topic?"

 Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself. 

Annotation versus abstracts 

An abstract is a paragraph at the beginning of the paper that discusses the main point of the original work. They typically do not include evaluation comments. 

Annotations can either be descriptive or evaluative. The annotated bibliography looks like a works cited page but includes an annotation after each source cited. 

Types of Annotations: 

Descriptive Annotations: Focuses on description. Describes the source by answering the following questions. 

Who wrote the document?

What does the document discuss?

When and where was the document written? 

Why was the document produced?

How was it provided to the public?

Evaluative Annotations: Focuses on description and evaluation. Includes a summary and critically assess the work for accuracy, relevance, and quality. 

Evaluative annotations help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project.

What does the annotation include?

Depending on your assignment and style guide, annotations may include some or all of the following information. 

• Should be no more than 150 words or 4 to 6 sentences long. 
• What is the main focus or purpose of the work?
• Who is the intended audience?
• ​How useful or relevant was the article to your topic?
• Was there any unique features that useful to you?
• What is the background and credibility of the author?
• What are any conclusions or observations that your reached about the article?

Which citation style to use?

There are many styles manuals with specific instructions on how to format your annotated bibliography. This largely depends on what your instructor prefers or your subject discipline. Check out our citation guides for more information. 

Additional Information

Why doesn't APA have an official APA-approved format for annotated bibliographies?

Always consult your instructor about the format of an annotated bibliography for your class assignments. These guides provide you with examples of various styles for annotated bibliographies and they may not be in the format required by your instructor. 

Citation Examples and Annotations

Book Citation with Descriptive Annotation

Liroff, R. A., & G. G. Davis. (1981). Protecting open space: Land use control in the Adirondack Park. Cambridge, MA: Ballinger.

This book describes the implementation of regional planning and land use regulation in the Adirondack Park in upstate New York. The authors provide program evaluations of the Adirondack Park Agency’s regulatory and local planning assistance programs.

Journal Article Citation with Evaluative Annotation

Gottlieb, P. D. (1995). The “golden egg” as a natural resource: Toward a normative theory of growth management. Society and Natural Resources, 8, (5): 49-56.

This article explains the dilemma faced by North American suburbs, which demand both preservation of local amenities (to protect quality of life) and physical development (to expand the tax base). Growth management has been proposed as a policy solution to this dilemma. An analogy is made between this approach and resource economics. The author concludes that the growth management debate raises legitimate issues of sustainability and efficiency.

Book Citation

Lee, Seok-hoon, Yong-pil Kim, Nigel Hemmington, and Deok-kyun Yun. “Competitive Service Quality Improvement (CSQI): A Case Study in the Fast-Food Industry.” Food Service Technology 4 (2004): 75-84.

In this highly technical paper, three industrial engineering professors in Korea and one services management professor in the UK discuss the mathematical limitations of the popular SERVQUAL scales. Significantly, they also aim to measure service quality in the fast-food industry, a neglected area of study. Unfortunately, the paper’s sophisticated analytical methods make it inaccessible to all but the most expert of researchers.

Battle, Ken. “Child Poverty: The Evolution and Impact of Child Benefits.”  A Question of Commitment: Children's Rights in Canada . Ed. Katherine Covell and R.Brian Howe. Waterloo, ON: Wilfrid Laurier University Press. 2007. 21-44.

             Ken Battle draws on a close study of government documents, as well as his own research as an extensively-published policy analyst, to explain Canadian child benefit programs.  He outlines some fundamental assumptions supporting the belief that all society members should contribute to the upbringing of children.  His comparison of child poverty rates in a number of countries is a useful wake-up to anyone assuming Canadian society is doing a good job of protecting children.  Battle pays particular attention to the National Child Benefit (NCB), arguing that it did not deserve to be criticized by politicians and journalists.  He outlines the NCB’s development, costs, and benefits, and laments that the Conservative government scaled it back in favour of the inferior Universal Child Care Benefit (UCCB).  However, he relies too heavily on his own work; he is the sole or primary author of almost half the sources in his bibliography.  He could make this work stronger by drawing from others' perspectives and analyses.  However, Battle does offer a valuable source for this essay, because the chapter provides a concise overview of government-funded assistance currently available to parents.  This offers context for analyzing the scope and financial reality of child poverty in Canada.

Journal Article Example

  Kerr, Don and Roderic Beaujot. “Child Poverty and Family Structure in Canada, 1981-1997.”  Journal of Comparative Family Studies  34.3 (2003): 321-335.

             Sociology professors Kerr and Beaujot analyze the demographics of impoverished families.  Drawing on data from Canada’s annual Survey of Consumer Finances, the authors consider whether each family had one or two parents, the age of single parents, and the number of children in each household.  They analyze child poverty rates in light of both these demographic factors and larger economic issues.  Kerr and Beaujot use this data to argue that.

An annotated bibliography is a list of cited resources related to a particular topic or arranged thematically that include a brief descriptive or evaluative summary. The annotated bibliography can be arranged chronologically by date of publication or alphabetically by author, with citations to print and/or digital materials, such as, books, newspaper articles, journal articles, dissertations, government documents, pamphlets, web sites, etc., multimedia sources like films and audio recordings, or documents and materials preserved in archival collections.

Importance of a Good Annotated Bibliography

In lieu of writing a formal research paper or in preparation for a larger writing project, your professor may ask you to develop an annotated bibliography. An annotated bibliography may be assigned for a number of reasons, including :

• To show that you can identify and evaluate the literature underpinning a research problem;
• To demonstrate that you can identify and conduct an effective and thorough review of pertinent literature;
• To develop skills in discerning the most relevant research studies from those which have only superficial relevance to your topic;
• To explore how different types of sources contribute to understanding the research problem;
• To be thoroughly engaged with individual sources in order to strengthen your analytical skills; or,
• To share sources among your classmates so that, collectively, everyone in the class obtains a comprehensive understanding of research about a particular topic.

On a broader level, writing an annotated bibliography can lay the foundation for conducting a larger research project. It serves as a method to evaluate what research has been conducted and where your proposed study may fit within it. By critically analyzing and synthesizing the contents of a variety of sources, you can begin to evaluate what the key issues are in relation to the research problem and, by so doing, gain a better perspective about the deliberations taking place among scholars. As a result of this analysis, you are better prepared to develop your own point of view and contributions to the literature.

In summary, creating a good annotated bibliography...

• Encourages you to think critically about the content of the works you are using, their place within the broader field of study, and their relation to your own research, assumptions, and ideas;
• Gives you practical experience conducting a thorough review of the literature concerning a research problem;
• Provides evidence that you have read and understood your sources;
• Establishes validity for the research you have done and of you as a researcher;
• Gives you the opportunity to consider and include key digital, multimedia, or archival materials among your review of the literature;
• Situates your study and underlying research problem in a continuing conversation among scholars;
• Provides an opportunity for others to determine whether a source will be helpful for their research; and,
• Could help researchers determine whether they are interested in a topic by providing background information and an idea of the kind of scholarly investigations that have been conducted in a particular area of study.

In summary, writing an annotated bibliography helps you develop skills related to critically reading and identifying the key points of a research study and to effectively synthesize the content in a way that helps the reader determine its validity and usefulness in relation to the research problem or topic of investigation.

NOTE: Do not confuse annotating source materials in the social sciences with annotating source materials in the arts and humanities. Rather than encompassing forms of synopsis and critical analysis, an annotation assignment in arts and humanities courses refers to the systematic interpretation of literary texts, art works, musical scores, performances, and other forms of creative human communication for the purpose of clarifying and encouraging analytical thinking about what the author(s)/creator(s) have written or created. They are assigned to encourage students to actively engage with the text or creative object.

Structure and Writing Style

I.  Types

• Descriptive : This annotation describes the source without summarizing the actual argument, hypothesis, or message in the content. Like an abstract , it describes what the source addresses, what issues are being investigated, and any special features, such as appendices or bibliographies, that are used to supplement the main text. What it does not include is any evaluation or criticism of the content. This type of annotation seeks to answer the question: Does this source cover or address the topic I am researching? Collectively, this type of annotated bibliography synthesizes prior research about a topic or serves as a review of the literature before conducting a broader research study.
• Informative/Summative : This type of annotation summarizes what the content, message, or argument of the source is. It generally contains the hypothesis, methodology, and conclusion or findings, but like the descriptive type, you are not offering your own evaluative comments about such content. This type of annotation seeks to answer these types of questions: What are the author's main arguments? What are the key findings? What conclusions or recommended actions did the author state?   Collectively, this type of annotated bibliography summarizes the way in which scholars have studied and documented outcomes about a topic.
• Evaluative/Critical/Analytical : This annotation includes your own evaluative statements about the content of a source. It is the most common type of annotation your professor will ask you to write. Your critique may focus on describing a study's strengths and weaknesses or it may describe the applicability of the conclusions to the research problem you are studying. This type of annotation seeks to answer these types of questions: Is the reasoning sound? Is the methodology sound? Does this source address all the relevant issues? How does this source compare to other sources on this topic? Collectively, this type of annotated bibliography offers a detailed analysis and critical assessment of the research literature about a topic.

NOTE:   There are a variety of strategies you can use to critically evaluate a source based on its content, purpose, and format. A description of these strategies can be found here .

II.  Choosing Sources for Your Bibliography

There are two good strategies to begin identifying possible sources for your bibliography--one that looks back into the literature and one that projects forward based on tracking sources cited by researchers.

• The first strategy is to identify several recently published [within the past few years] scholarly books using the USC Libraries catalog or journal articles found by searching a comprehensive, multidisciplinary database like ProQuest Multiple . Review the list of references to sources cited by the author(s). Review these citations to identify prior research published about your topic. For a complete list of scholarly databases GO HERE .
• The second strategy is to identify one or more books, book chapters, journal articles, or research reports on your topic and paste the title of the item into Google Scholar [e.g., from Negotiation Journal , entering the title of the article, " Civic Fusion: Moving from Certainty through Not Knowing to Curiosity " ]. If it is a short title or it uses a lot of common words, place quotation marks around the title so Google Scholar searches the source as a phrase rather than a combination of individual words. Below the citation may be a "Cited by" reference link followed by a number [e.g., Cited by 45]. This number refers to the number of times a source has subsequently been cited by other authors in other sources after the item you found was published.

Your method for selecting which sources to annotate depends on the purpose of the assignment and the research problem you are investigating . For example, if the course is on international social movements and the research problem you choose to study is to compare cultural factors that led to protests in Egypt with the factors that led to protests against the government of the Philippines in  the 1980's, you should consider including non-U.S., historical, and, if possible, foreign language sources in your bibliography.

NOTE:   Appropriate sources to include can be anything that you believe has value in understanding the research problem . Be creative in thinking about possible sources, including non-textual items, such as, films, maps, photographs, and audio recordings, or archival documents and primary source materials, such as, diaries, government documents, collections of personal correspondence, meeting minutes, or official memorandums. If you want to include these types of sources in your annotated bibliography, consult with a librarian if you're not sure where to locate them.

III.  Strategies to Define the Scope of Your Bibliography

It is important that the scope of sources cited and summarized in your bibliography are well-defined and sufficiently narrow in coverage to ensure that you're not overwhelmed by the number of potential items to consider including. Many of the general strategies used to narrow a topic for a research paper are the same that be applied to framing the scope of sources to include in an annotated bibliography.

• Aspect -- choose one lens through which to view the research problem, or look at just one facet of your topic [e.g., rather than annotating a bibliography of sources about the role of food in religious rituals, create a bibliography on the role of food in Hindu ceremonies].
• Time -- the shorter the time period to be covered, the more narrow the focus [e.g., rather than political scandals of the 20th century, cite literature on political scandals during the 1980s].
• Comparative -- a list of resources that focus on comparing two or more issues related to the broader research topic can be used to narrow the scope of your bibliography [e.g., rather than college student activism during the 20th century, cite literature that compares student activism in the 1930s and the 1960s]
• Geography -- the smaller the area of analysis, the fewer items there are to consider including in your bibliography [e.g., rather than cite sources about trade relations in West Africa, include only sources that examine, as a case study, trade relations between Niger and Cameroon].
• Type -- focus your bibliography on a specific type or class of people, places, or things [e.g., rather than health care provision in Japan, cite research on health care provided to the elderly in Japan].
• Source -- your bibliography includes specific types of materials [e.g., only books, only scholarly journal articles, only films, only archival materials, etc.]. However, be sure to describe why only one type of source is appropriate.
• Combination -- use two or more of the above strategies to focus your bibliography very narrowly or to broaden coverage of a very specific research problem [e.g., cite literature only about political scandals during the 1980s that took place in Great Britain].

IV.  Assessing the Relevance and Value of Sources All the items included in your bibliography should reflect the source's contribution to understanding the research problem . In order to determine how you will use the source or define its contribution, you will need to critically evaluate the quality of the central argument within the source or, in the case of including  non-textual items, determine how the source contributes to understanding the research problem [e.g., if the bibliography lists sources about outreach strategies to homeless populations, a non-textual source would be a film that profiles the life of a homeless person]. Specific elements to assess a research study include an item’s overall value in relation to other sources on the topic, its limitations, its effectiveness in defining the research problem, the methodology used, the quality of the evidence, and the strength of the author’s conclusions and/or recommendations. With this in mind, determining whether a source should be included in your bibliography depends on how you think about and answer the following questions related to its content:

• Are you interested in the way the author(s) frame the research questions or in the way the author goes about investigating the questions [the method]?
• Does the research findings make new connections or promote new ways of understanding the problem?
• Are you interested in the way the author(s) use a theoretical framework or a key concept?
• Does the source refer to and analyze a particular body of evidence that you want to highlight?
• How are the author's conclusions relevant to your overall investigation of the topic?

V.  Format and Content

The format of an annotated bibliography can differ depending on its purpose and the nature of the assignment. Contents may be listed alphabetically by author, arranged chronologically by publication date, or arranged under headings that list different types of sources [i.e., books, articles, government documents, research reports, etc.]. If the bibliography includes a lot of sources, items may also be subdivided thematically, by time periods of coverage or publication, or by source type. If you are unsure, ask your professor for specific guidelines in terms of length, focus, and the type of annotation you are to write. Note that most professors assign annotated bibliographies that only need to be arranged alphabetically by author.

Introduction Your bibliography should include an introduction that describes the research problem or topic being covered, including any limits placed on items to be included [e.g., only material published in the last ten years], explains the method used to identify possible sources [such as databases you searched or methods used to identify sources], the rationale for selecting the sources, and, if appropriate, an explanation stating why specific types of some sources were deliberately excluded. The introduction's length depends, in general, on the complexity of the topic and the variety of sources included.

Citation This first part of your entry contains the bibliographic information written in a standard documentation style , such as, MLA, Chicago, or APA. Ask your professor what style is most appropriate, and be consistent! If your professor does not have a preferred citation style, choose the type you are most familiar with or that is used predominantly within your major or area of study.

Annotation The second part of your entry should summarize, in paragraph form, the content of the source. What you say about the source is dictated by the type of annotation you are asked to write [see above]. In most cases, however, your annotation should describe the content and provide critical commentary that evaluates the source and its relationship to the topic.

In general, the annotation should include one to three sentences about the item in the following order : (1) an introduction of the item; (2) a brief description of what the study was intended to achieve and the research methods used to gather information; ( 3) the scope of study [i.e., limits and boundaries of the research related to sample size, area of concern, targeted groups examined, or extent of focus on the problem]; (4) a statement about the study's usefulness in relation to your research and the topic; (5) a note concerning any limitations found in the study; (6) a summary of any recommendations or further research offered by the author(s); and, (7) a critical statement that elucidates how the source clarifies your topic or pertains to the research problem.

Things to think critically about when writing the annotation include:

• Does the source offer a good introduction on the issue?
• Does the source effectively address the issue?
• Would novices find the work accessible or is it intended for an audience already familiar with the topic?
• What limitations does the source have [reading level, timeliness, reliability, etc.]?
• Are any special features, such as, appendices or non-textual elements effectively presented?
• What is your overall reaction to the source?
• If it's a website or online resource, is it up-to-date, well-organized, and easy to read, use, and navigate?

Length An annotation can vary in length from a few sentences to more than a page, single-spaced. However, they are normally about 300 words--the length of a standard paragraph. The length also depends on the purpose of the annotated bibliography [critical assessments are generally lengthier than descriptive annotations] and the type of source [e.g., books generally require a more detailed annotation than a magazine article]. If you are just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need to devote more space.

The quality and usefulness of your bibliography will depend on your selection of sources. Define the scope of your research carefully to make sound judgments about what you include and exclude.

What is an annotated bibliography?

An annotated bibliography is a list of citations to books, articles, and documents that follows the appropriate style format for the discipline (MLA, APA, Chicago, etc). Each citation is followed by a brief (usually about 150 word) descriptive and evaluative paragraph -- the annotation. Unlike abstracts, which are purely descriptive summaries often found at the beginning of scholarly journal articles or in periodical indexes, annotations are descriptive and critical. 

The purpose of the annotation is to  inform the reader of the relevance, accuracy, and quality of the sources cited .  The annotation exposes the author's point of view, clarity and appropriateness of expression, and authority.

How do I create an annotated bibliography?

• Locate and record citations to books, periodicals, and documents that contain useful information and ideas on your topic.
• Review the items. Choose those sources that provide a  variety of perspectives on your topic.
• Cite the book, article, or document using the appropriate style. 
• Write a concise annotation that  summarizes the central theme and scope o f the item.

Include  one or more sentences  that:

o    evaluate the authority or background of the author, 

o    comment on the intended audience, 

o    compare or contrast this work with another you have cited, or 

o    explain how this work illuminates your bibliography topic.

The annotation should include most, if not all, of the following elements:

• Explanation of the main purpose and scope of t he cited work;
• Brief description of the work's format and content;
• Theoretical basis and currency of the author's argument; 
• Author's intellectual / academic credentials; 
• Work's intended audience;
• Value and significance of the work as a contribution to the subject under consideration;
• Possible shortcomings or bias in the work;
• Any significant special features of the work (e.g., glossary, appendices, particularly good index);
• Your own brief impression of the work.

An annotated bibliography is an  original work created by you  for a wider audience, usually faculty and colleagues. Copying any of the above elements from the source and including it in your annotated bibliography is plagiarism and intellectual dishonesty.

Writing an Annotated Bibliography

An annotated bibliography is a summary and evaluation of a resource. Writing an annotated bibliography will help you gain an in-depth understanding of your topics and is useful for organizing and cataloging resources for use when developing an argument. An annotated bibliography begins with an APA formatted reference followed by one or two paragraphs of text that summarizes the study, evaluates the reliability of the information, and evaluates how the information relates to previous and future research. 

This table provides a high-level outline of the structure of a research article and how each section relates to important information for developing an annotated bibliography.

Annotated Bibliography Sample Outline

Annotated primary scientific literature is a teaching and learning resource that provides scaffolding for undergraduate students acculturating to the authentic scientific practice of obtaining and evaluating information through the medium of primary scientific literature. Utilizing annotated primary scientific literature as an integrated pedagogical tool could enable more widespread use of primary scientific literature in undergraduate science classrooms with minimal disruption to existing syllabi. Research is ongoing to determine an optimal implementation protocol, with these preliminary iterations presented here serving as a first look at how students respond to annotated primary scientific literature. The undergraduate biology student participants in our study did not, in general, have an abundance of experience reading primary scientific literature; however, they found the annotations useful, especially for vocabulary and graph interpretation. We present here an implementation protocol for using annotated primary literature in the classroom that minimizes the use of valuable classroom time and requires no additional pedagogical training for instructors.

This Community Page article presents Science in the Classroom (SitC), a tool for undergraduate educators to introduce their students to primary scientific literature. Annotations scaffold the readers so that authentic scientific practices are explained and recognized for their importance in scientific communications.

A major output of public research universities is primary scientific literature, in addition to educating students and conferring degrees. It is imperative for researchers and universities to increase the transparency and outreach of the primary research literature they produce. However, most primary scientific literature remains unknown and/or inaccessible to the public, because it is published in journals targeting academics in the same field and is often placed behind journal paywalls [ 1 ].

Public research universities also have a responsibility to produce scientifically literate graduates [ 2 , 3 ]. Many students graduate without an understanding of scientific practices and an acculturation to interpreting scientific communication, especially primary scientific literature [ 4 , 5 ]. One way to potentially improve scientific literacy overall and develop specific skills, such as interpreting scientific communication, is to incorporate primary scientific literature into the undergraduate curricula and provide pedagogical tools that may help bridge the divide between everyday language and the language used by experts [ 6 – 11 ].

The study of primary scientific literature as a pedagogical tool in undergraduate biology courses has led to innovative approaches. The most well-known of these may be the Consider, Read, Elucidate the hypotheses, Analyze and interpret the data, and Think of the next Experiment (CREATE) method, in which faculty redesign their existing courses around primary scientific literature in order to provide an intensive and comprehensive analysis of primary scientific literature for undergraduates [ 6 , 12 – 14 ]. Although this type of a semester-long innovative elective course provided student benefits, adding an entire course to a degree sequence may prove difficult and by definition, does not impact students that choose not to include them in an already credit-crunched plan of study. This credit-crunch is especially prevalent at institutions such as the one in this study, Florida International University (FIU), where any additional credit hours are charged at out-of-state tuition rates. Therefore, it would benefit biology education, and biology as a field of study, to develop innovative ways to utilize primary scientific literature as a pedagogical tool, ideally with a minimal impact to existing plans of study and time investment from course instructors.

A growing body of research shows that less-intensive interventions using primary scientific literature can be valuable and useful in science, technology, engineering, and math (STEM) education, with the greatest amount of research happening at the undergraduate level. Programs include journal clubs, data and figure exploration, and tutorials on how to read primary scientific literature [ 15 – 17 ]. Assessment tools used to evaluate these interventions are equally as diverse, ranging from rubrics to validated surveys [ 18 , 19 ].

Annotated primary scientific literature

Annotated primary scientific literature is designed to help readers interpret complex science by overlaying additional information on a scientific research article. Preserving the original text and its context is what makes annotated primary scientific research literature unique from other genres that modify or rewrite the original text. This preservation is the key difference between annotated primary scientific literature and adapted primary literature, an approach that takes portions of primary scientific literature and rewrites the original content to turn them into pedagogical tools [ 20 ]. Science in the Classroom (SitC; www.scienceintheclassroom.org ) is a highly developed and sophisticated example of annotated primary scientific literature that we decided has potential for classroom pedagogical use.

SitC, a collection of freely available annotated papers, aims to make primary scientific research literature more accessible to students and educators. The repository of annotated primary scientific literature articles is accessible to educators and searchable by keyword, classified by topics, and grouped in collections. The process of reading and deconstructing scientific literature in undergraduate courses has been shown to result in students potentially gaining an understanding of scientific practices, such as how scientists design their experiments and present their results, essentially allowing students to experience the logic behind drawing conclusions from a set of data [ 6 , 7 , 12 – 14 ].

Annotated primary scientific literature uses the original text of research articles along with a “Learning Lens” overlay, designed to provide students tools to use for interpretation. The “Learning Lens” is used to selectively highlight different parts of the text and is composed of seven headings: Glossary, Previous work, Author's experiments, Conclusions, News and policy links, Connect to learning standards, and References and notes, which are color-coded to match the corresponding text of the research article. For example, an annotated glossary term, when clicked on, will produce a pop-up box containing the definition of the word ( Fig 1 ). Annotations contained within the “Learning Lens” have been designed to be at the reading comprehension level of a first-year undergraduate student, and ongoing evaluation efforts have provided evidence that this goal is being met [ 21 ].

Annotated primary literature as a pedagogical tool

Annotations provide an educational scaffold that could help students become more comfortable with reading scientific papers. We propose annotated primary scientific literature as an example of a resource that can be incorporated into existing courses and provide scaffolding that may help undergraduate students develop skills necessary to read primary scientific literature while requiring a minimal time investment from instructors. Using annotated primary scientific literature as a pedagogical tool not only could potentially help universities develop scientifically literate graduates, but it may also broaden the impact of primary scientific research literature produced by faculty.

The previously mentioned pedagogical tools and curriculum transformations can require a substantial investment of time and effort from the university, faculty, and staff. Therefore, additional tools and opportunities should be considered in order to achieve a wider variety of complementary opportunities for teaching with authentic scientific practices and engaging students in reading primary scientific literature [ 22 ]. We hypothesize that the incorporation of annotated primary scientific literature in the classroom represents one of these opportunities.

In this pilot study, we had a goal of developing an implementation protocol that could incorporate annotated primary scientific literature into undergraduate courses with a minimal time investment for instructors and minimal disruption and alteration to existing courses and plans of study.

Implementation of annotated primary scientific literature

All data were collected in accordance with an approved FIU Institutional Review Board protocol #17–0398 and #17–0105. Our initial attempts to develop an implementation protocol for using annotated primary scientific literature as a pedagogical tool had the educational goal of introducing students to the “Learning Lens” annotations and observing how instructors and students used the tool. Initial attempts to incorporate annotated primary scientific literature focused on undergraduate biology courses at FIU, including General Biology II, Ecology, and Plant Life History. The implementation sessions were run iteratively during the same semester, ensuring that students did not overlap, and each class had only one implementation session. We describe two variations of our implementations here.

Students involved in the study self-reported their major, with 76% being biology majors. We did not collect any data on students’ prior knowledge of biology, but the majority of students in these classes are first- or second-year students.

We used the same annotated piece of primary scientific literature for all in-class activities described in this study: “Caffeine in floral nectar enhances a pollinator's memory of reward” ( https://tinyurl.com/k7m329g ). We chose an article that incorporated many different aspects of biology, including evolution, ecosystem interactions, basic botany, learning and memory, and animal behavior in a single study, making this paper applicable in a wide variety of undergraduate courses.

The objectives were to introduce undergraduate students to annotated primary scientific literature and collect baseline data on how students interacted with the annotations themselves. The first implementation involved a one-time intervention, connected to the student’s coursework, conducted by the researchers and began with an approximately 5-minute orientation to annotated primary scientific literature. This orientation included how to use the “Learning Lens” and a brief overview of the importance of primary scientific literature. Students were then given 20 minutes to read the selected piece of annotated primary scientific literature. At the 20-minute time point, a Qualtrics (online survey software; Provo, Utah and Seattle, Washington) link was provided, and if they were done reading, students could begin answering the feedback questionnaire. Students were given an additional 20 minutes to complete the questionnaire. Collecting and analyzing this first round of pilot data allowed for reflection on opportunities for iterative improvement.

In addition to the questionnaire data, feedback was collected through in-class activity observations conducted by the researchers. We kept detailed field notes indicating when students appeared on task, i.e., independently interacting with annotated primary scientific literature. We also noted when alternative tasks were observed, i.e., students checking email or social media, and when task completion appeared to have occurred. During the implementation, our in-class observations estimated an average time on task, i.e., interacting with annotated primary scientific literature, to be 10 minutes, because there was a noticeable increase in classroom noise after this time point. We confirmed this by using Adobe Analytics (Adobe, San Jose, California), which measures the time spent on a website by each user. We measured an average time spent on annotated primary scientific literature of 13 minutes. Due to limitations of Adobe Analytics, we are unable to collect individual data points and were limited to an aggregate average for the entire class. Note that the difference between the observed time spent on the activity and the digital measure can be explained by Adobe Analytics averaging all participants’ time spent on the article page.

The main student feedback was collected through a questionnaire containing both quantitative (content questions) and qualitative items (i.e., “what did you like about this activity?”). One of the key ideas we garnered from the qualitative data was that a one-time intervention was perceived by students as somewhat discordant when a connection between the article they read and the content they were covering at the time in their course was not made explicit by their course instructor ( Table 1 ).

When asked if the topic of the paper related to their course, students in this iteration gave feedback such as this activity was “only slightly relevant to the course,” and “no, we[‘re] studying plants” despite the article being explicitly about caffeine production by plants in order to attract pollinators. Additionally, we were uncertain that we had connected with the students as researchers in the same way as the instructor with whom the students had built a relationship.

Although some students may have not perceived a connection between the article content and their course content, in general, students found the annotations useful, especially regarding graphs and vocabulary interpretation. Examples of student responses can be seen in Table 2 .

For our second iteration, we decided to address the issues of students feeling discordant by having the course instructors introduce the article and annotated primary scientific literature activity themselves. Additionally, we asked instructors to explicitly connect the annotated paper to current course content. With both of these procedures in place, the average time students engaged with the annotated article, as measured by Adobe Analytics, increased to 19 minutes ( Fig 2 ).

This new implementation, in which the instructor introduced the piece of annotated primary scientific literature and annotated primary scientific literature activity, not only appeared to increase the time that students engaged with the material, but it also removed the manpower requirement for the researchers to be present in every classroom in order to describe and implement the activity. This could allow for a more widespread implementation of annotated primary scientific literature as a pedagogical tool. It was also apparent that students introduced to the activity by their course instructor were more readily able to recognize the connections between reading primary scientific research literature and their course content, which can be seen in student responses in Table 3 .

When asked if the topic of the paper related to their course, students in this iteration stated “This article related to 3 different courses I am taking this semester,” “yes it most certainly did,” “yes! We’re learning about pollination,” and that “…scientific papers on new experiments …are important.”

During the initial iterations of the implementation protocol, students read the annotated articles and completed an assessment during class time. However, a growing concern was feasibility of an in-class assignment due to the time requirement and allowing for instructor flexibility in scheduling. While observing a senior lecturer at FIU, who was not involved in this current study, and his existing implementation method of students reading primary scientific literature as homework and answering iClicker questions at the beginning of the following class, the researchers noticed an increased enthusiasm among the students during the class discussion. Supporting this observation, the history of research on the use of clickers in the classroom shows an increase in feelings of class involvement [ 23 ] and learning gains in students [ 24 ]. Because of the observations and support from instructors, the decision was made to adopt the homework protocol moving forward with future implementations. The homework protocol allows for more instructor freedom in selecting articles relevant to course content, reduces the class time required for implementation, and separates content questions from a pre–post attitude and motivation questionnaire. Using articles as homework also allows for instructors to utilize as many articles as they wish, but for this project moving forward, in future implementations, we will require a minimum of three articles over the course of a semester. We are currently piloting an implementation protocol using annotated primary scientific literature as a homework assignment and are excited to see how instructors and students use annotated primary scientific literature moving forward.

Advice to others

In the ongoing iterative development of an implementation protocol for annotated primary scientific literature, the most fruitful exercise has been reflection. This is great practice for any educator or educational researcher during the curriculum or pedagogical tool development process. Reflection on early classroom implementations helped us identify the opportunities for improvement in our subsequent protocol iterations and allowed us to make modifications based upon quantitative, qualitative, and observational data. One example of changes coming from reflection was noticing that during an implementation, students were opening the assessment without reading the article and using the “find” feature within the article to find answers to assessment questions. This led to preventing entry into the assessment until the time for reading had elapsed. Our subsequent classroom observations showed us that this forced students to interact with the article and be more thoughtful about their answers to the assessment, i.e., answers were not cut-and-pasted from the article text. We advise others to continue this practice of thoughtful reflection when using annotated primary scientific literature as a pedagogical tool. We also welcome any feedback or alternative uses of annotated primary scientific literature.

Future steps

The latest annotated primary scientific literature implementation protocol iteration is being pilot tested during fall 2018. Focusing more on robust evaluation now that implementation obstacles have been overcome will allow us to determine the effectiveness of annotated primary scientific literature as a pedagogical tool in undergraduate biology classrooms. Future studies are being designed to examine students’ scientific literacy before and after completing the annotated article activities using a previously validated scientific literacy instrument (Test of Scientific Literacy Skills [TOSLS]) [ 2 ]. Additionally, we aim to measure students’ subjective task values with regards to reading primary scientific research literature [ 25 – 28 ], as well as their primary scientific literature reading self-efficacy [ 29 – 32 ].

We hope to spread the word about annotated primary scientific literature and investigate its potential impacts on student learning and motivation as we further refine our implementation protocol and propagate beyond our department and institution.

How to Write an Annotated Bibliography for Research

Introduction

What is an annotated bibliography, writing an annotated bibliography, analyzing an annotated bibliography.

A literature review is more than just a collection of articles that inform your research project. For a literature review to benefit your research, you need to structure it in a way that organizes scientific knowledge and synthesizes this knowledge to justify your research project.

An annotated bibliography is one tool that provides that organization. In this article, we will explore why it's important to craft an annotated bibliography for your research and what to put into one so it can serve as a foundation for your future research inquiries.

Annotated bibliographies are a tool to organize existing research in a way that helps you to demonstrate your familiarity with a particular research topic. Each annotated bibliography entry outlines each study in your literature review and includes your analysis of the study.

A bibliography refers to the full list of references included in your literature review. An annotation refers to notes, summaries, and reflections about each reference. Thus, an annotated bibliography consists of the references in your literature review and your notes on each reference.

How is it different from a literature review?

A literature review is a collection of articles on the latest research and the subsequent synthesis of the theoretical developments arising from that research. An annotated bibliography can help you achieve that synthesis by organizing the information in a systematic way and providing space for your analysis (and critiques, where appropriate).

How long is an annotated bibliography?

An annotated bibliography includes all the relevant contemporary research conducted on the topics covered by the research questions you want to address. Ultimately, the current state of the research area you are addressing will dictate the length of your literature review and annotated bibliography.

Research topics that have greater theoretical coherence will have more relevant studies, while less-explored research questions will have fewer studies. In the end, it is the up to the researcher's judgment to determine whether they have collected sufficient research for their annotated bibliography.

Organization of knowledge

We've all likely made the mistake of simply downloading journal articles and other scholarly publications relevant to our research and throwing them in a folder on our computer, seldom to be read until it comes time to write our paper. At this point, these articles are just a jumble of information that is difficult to sift through. Of course, it is possible to synthesize knowledge without using annotated bibliographies, but the process will be time-consuming and tedious.

Think of information that you collect for an annotated bibliography as unstructured data that needs to be organized in a way that facilitates the identification of useful insights. Having all the existing research distilled into a succinct form is important, but providing a structure that organizes that knowledge will make it much easier to synthesize theory and present theory in your resulting research manuscripts or presentations.

An annotated bibliography is more of a visual organizer for your thoughts about the existing research than it is a required element in your paper or presentation. That said, there should be an intentional process applied to the writing of annotated bibliographies that is important to outline in this section.

Conducting a literature review

The literature review informs the annotated bibliography and the subsequent research inquiries that it provokes. Ultimately, you will want to search for the most recent scholarly articles containing the most relevant information that pertains to the concept or theory you want to research.

When putting together a literature review, remember to search for the most recent research articles outlining important theoretical developments relevant to your research question. Be sure to consult various web sites, scholarly databases, and bibliographies of key articles for research that aligns with your research interests.

How do you format an annotated bibliography?

While there is no particular standard used to write annotations, there are a few common criteria used to analyze existing research sources:

• Bibliographic citation . Citing research papers is an important part of the research publication process. By providing a reference in the proper citation format now, you can make it easier to copy and paste this reference entry into your paper later.
• Keywords . Articles often come with a list of keywords that make it easy for you to search for when conducting your literature review. They are also useful for determining what aspects of your research inquiry are and aren't being explored by the collected research.
• Study description . A brief summary (typically one paragraph) of each research paper can help you conduct your literature review. Complete sentences may not be necessary, but writing your own understanding of each paper now can make writing your background section easier later on.
• Research context . Context is important because cultural influences, historical factors, and other sociocultural resources inform the data collection and analysis. Be sure to outline the relevant details of the place in which the study was conducted.
• Methods . The various methods employed in qualitative research look at phenomena in profoundly different ways. Make sure to list the methods for each study to identify any methodological gaps when analyzing your annotated bibliography.
• Potential critiques . Use this space in your annotated bibliography to note what each study has overlooked in terms of theory or methods. These critiques will contribute to the problem statement that defines your research question and the resulting study.

Other items to include in your reference list might include DOI numbers, theoretical frameworks , study limitations, and any other information that would be worth sorting or filtering when you conduct your analysis .

Ultimately, the annotated bibliography format is either determined by your assignment guidelines (if it is a requirement of your coursework) or your own judgment (when you are distilling research for designing a study ). Some annotated bibliographies are written in paragraph form like a series of little essays, each describing a particular bibliographic citation. Others can also take the form of a table that visually organizes the information in a form where it is easy to spot patterns and limitations.

Whatever you decide, the format should be consistent across each annotated bibliography entry. The effort it takes to consistently format your bibliography will save time later on as your collected research will be easier to read and synthesize.

If you do use your annotated bibliography in your research paper for publication, ensure that your citations conform to Modern Language Association (MLA) format, American Psychological Association (APA) format, or the reference format used in the journal to which you are submitting your research. You can refer to a publication manual like the MLA Handbook, but it's probably more helpful to look for annotated bibliography examples online that can serve as models for your own bibliography.

Doing a quick search for journal articles that synthesize existing research in a literature review might give you some useful annotated bibliography examples.

Once you have organized your literature review in an annotated bibliography, the next step is identifying useful pathways for your own research to explore. Locating the gaps in the current scholarship is a necessary task for formulating a research question , defining your theoretical framework , and designing your overall study .

The Code-Document Analysis tool in ATLAS.ti can serve as a good annotated bibliography generator. Code your collected studies and analyze those codes in the Code-Document Analysis tool to gain a sense of what theories and developments are discussed in each study. By generating a visual understanding of the current state of research, you can make it easier to define subsequent lines of research inquiry that justify the study you want to conduct.

14.1 Compiling Sources for an Annotated Bibliography

Learning outcomes.

By the end of this section, you will be able to:

• Integrate your ideas with ideas from related sources.
• Locate, compile, and evaluate primary, secondary, and tertiary research materials related to your topic.

A bibliography is a list of the sources you use when doing research for a project or composition. Named for the Greek terms biblion , meaning “book,” and graphos , meaning “something written,” bibliographies today compile more than just books. Often they include academic journal articles, periodicals, websites, and multimedia texts such as videos. A bibliography alone, at the end of a research work, also may be labeled “References” or “Works Cited,” depending on the citation style you are using. The bibliography lists information about each source, including author, title, publisher, and publication date. Each set of source information, or each individual entry, listed in the bibliography or noted within the body of the composition is called a citation .

Bibliographies include formal documentation entries that serve several purposes:

• They help you organize your own research on a topic and narrow your topic, thesis, or argument.
• They help you build knowledge.
• They strengthen your arguments by offering proof that your research comes from trustworthy sources.
• They enable readers to do more research on the topic.
• They create a community of researchers, thus adding to the ongoing conversation on the research topic.
• They give credit to authors and sources from which you draw and support your ideas.

Annotated bibliography expand on typical bibliographies by including information beyond the basic citation information and commentary on the source. Although they present each formal documentation entry as it would appear in a source list such as a works cited page, an annotated bibliography includes two types of additional information. First, following the documentation entry is a short description of the work, including information about its authors and how it was or can be used in a research project. Second is an evaluation of the work’s validity, reliability, and/or bias. The purpose of the annotation is to summarize, assess, and reflect on the source. Annotations can be both explanatory and analytical, helping readers understand the research you used to formulate your argument. An annotated bibliography can also help you demonstrate that you have read the sources you will potentially cite in your work. It is a tool to assist in the gathering of these sources and serves as a repository. You won’t necessarily use all the sources cited in your annotated bibliography in your final work, but gathering, evaluating, and documenting these sources is an integral part of the research process.

Compiling Sources

Research projects and compositions, particularly argumentative or position texts, require you to collect sources, devise a thesis, and then support that thesis through analysis of the evidence, including sources, you have compiled. With access to the Internet and an academic library, you will rarely encounter a shortage of sources for any given topic or argument. The real challenge may be sorting through all the available sources and determining which will be useful.

The first step in completing an annotated bibliography is to locate and compile sources to use in your research project. At the beginning, you do not need to be highly selective in this process, as you may not ultimately use every source. Therefore, gather any materials—including books, websites, professional journals, periodicals, and documents—that you think may contain valuable ideas about your topic. But where do you find sources that relate to your argument? And how do you choose which sources to use? This section will help you answer those questions and choose sources that will both enhance and challenge your claim, allowing you to confront contradictory evidence and synthesize ideas, or combine ideas from various sources, to produce a well-constructed original argument. See Research Process: Accessing and Recording Information for more information about sources and synthesizing information.

Primary, Secondary, and Tertiary Sources

In your research, you likely will use three types of sources: primary, secondary, and tertiary. During any research project, your use of these sources will depend on your topic, your thesis, and, ultimately, how you intend to use them. In all likelihood, you will need to seek out all three.

Primary Sources

Primary sources allow you to create your own analysis with the appropriate rhetorical approach. In the humanities disciplines, primary sources include original documents, data, images, and other compositions that provide a firsthand account of an event or a time in history. Typically, primary sources are created close in time to the event or period they represent and may include journal or diary entries, newspaper articles, government records, photographs, artworks, maps, speeches, films, and interviews. In scientific disciplines, primary sources provide information such as scientific discoveries, raw data, experimental and research results, and clinical trial findings. They may include published studies, scientific journal articles, and proceedings of meeting or conferences.

Primary sources also can include student-conducted interviews and surveys. Other primary sources may be found on websites such as the Library of Congress , the Historical Text Archive , government websites, and article databases. In all academic areas, primary sources are fact based, not interpretive. That is, they may be commenting on or interpreting something else, but they themselves are the source. For example, an article written during the 1840s condemning the practice of enslavement may interpret events occurring then, but it is a primary source document of its time.

Secondary Sources

Secondary sources , unlike primary sources, are interpretive. They often provide a secondhand account of an event or research results, analyze or clarify primary sources and scientific discoveries, or interpret a creative work. These sources are important for supporting or challenging your argument, addressing counterarguments, and synthesizing ideas. Secondary sources in the humanities disciplines include biographies, literary criticism, and reviews of the fine arts, among other sources. In the scientific disciplines, secondary sources encompass analyses of scientific studies or clinical trials, reviews of experimental results, and publications about the significance of studies or experiments. In some instances, the same item can serve as both a primary and a secondary source, depending on how it is used. For example, a journal article in which the author analyzes the impact of a clinical trial would serve as a secondary source. But if you instead count the number of journal articles that feature reports on a particular clinical trial, you might use them as primary sources because they would then serve as data points.

Table 14.1 provides examples of how primary and secondary sources often relate to one another.

Tertiary Sources

In addition to primary and secondary sources, you can use a tertiary source to summarize or digest information from primary and/or secondary sources. Because tertiary sources often condense information, they usually do not provide enough information on their own to support claims. However, they often contain a variety of citations that can help you identify and locate valuable primary and secondary sources. Researchers often use tertiary sources to find general, historical, or background information as well as a broad overview of a topic. Tertiary sources frequently placed in the secondary-source category include reference materials such as encyclopedias, textbooks, manuals, digests, and bibliographies. For more discussion on sources, see The Research Process: Where to Look for Existing Sources .

Authoritative Sources

Not all sources are created equally. You likely know already that you must vet sources—especially those you find on the Internet—for legitimacy, validity, and the presence of bias. For example, you probably know that the website Wikipedia is not considered a trustworthy source because it is open to user editing. This accessibility means the site’s authority cannot be established and, therefore, the source cannot effectively support or refute a claim you are attempting to make, though you can use it at times to point you to reliable sources. While so-called bad sources may be easy to spot, researchers may have more difficulty discriminating between sources that are authoritative and those that pose concerns. In fact, you may encounter a general hierarchy of sources in your compilation. Understanding this hierarchy can help you identify which sources to use and how to use them in your research.

Peer-Reviewed Academic Publications

This first tier of sources—the gold standard of research—includes academic literature, which consists of textbooks, essays, journals, articles, reports, and scholarly books. As scholarly works, these sources usually provide strong evidence for an author’s claims by reflecting rigorous research and scrutiny by experts in the field. These types of sources are most often published, sponsored, or supported by academic institutions, often a university or an academic association such as the Modern Language Association (MLA) . Such associations exist to encourage research and collaboration within their discipline, mostly through publications and conferences. To be published, academic works must pass through a rigorous process called peer review , in which scholars in the field evaluate it anonymously. You can find peer-reviewed academic sources in library catalogs, in article databases, and through Google Scholar online. Sometimes these sources require a subscription to access, but students often receive access through their school.

Academic articles, particularly in the social and other sciences, generally have most or all of the following sections, a structure you might recognize if you have written lab reports in science classes:

• Abstract . This short summary covers the purpose, methods, and findings of the paper. It may discuss briefly the implications or significance of the research.
• Introduction . The main part of the paper begins with an introduction that presents the issue or main idea addressed by the research, establishes its importance, and poses the author’s thesis.
• Review . Next comes an overview of previous academic research related to the topic, including a synthesis that makes a case for why the research is important and necessary.
• Data and Methods . The main part of the original research begins with a description of the data and methods used, including what data or information the author collected and how the author used it.
• Results . Data and methods are followed by results, detailing the significant findings from the experiment or research.
• Conclusion . In the conclusion, the author discusses the results in the context of the bigger picture, explaining the author’s position on how these results relate to the earlier review of literature and their significance in the broad scope of the topic. The author also may propose future research needs or point out unanswered questions.
• Works Cited or References . The paper ends with a list of all sources the author used in the research, including the review of literature. This often-overlooked portion of the composition is critical in evaluating the credibility of any paper that involves research.

Credible Nonacademic Sources

These sources, including articles, books, and reports, are second in authority only to peer-reviewed academic publications. Credible nonacademic sources are often about current events or discoveries not yet reviewed in academic circles and often provide a wider-ranging outlook on your topic. Peer-reviewed texts tend to be narrow and specific, whereas nonacademic texts from well-researched sources are often more accessible and can offer a broader perspective. These three major categories generally provide quality sources:

• Information, white papers, and reports from government and international agencies such as the United Nations , the World Health Organization , and the United States government
• Longer articles and reports from major newspapers, broadcast media, and magazines that are well regarded in academic circles, including the New York Times , the Wall Street Journal , the BBC, and the Economist
• Nonacademic books written by authors with expertise and credentials, who support their ideas with well-sourced information

To find nonacademic sources, search for .gov or .org sites related to your topic. A word of caution, however: know that sources ending in .org are often advocacy sites and, consequently, inherently biased toward whatever cause they are advocating. You also can look at academic article databases and search articles from major newspapers and magazines, both of which can be found online.

Short Informational Texts from Credible Websites and Periodicals

The next most authoritative sources are shorter newspaper articles or other pieces on credible websites. These articles tend to be limited in scope, as their authors report on a single issue or event. Although they do not often provide in-depth analysis, they can be a source of credible facts to support your argument. Alternatively, they can point you in the direction of more detailed or rigorous sources that will enhance your research by tracing the original texts or sources on which the articles are based. Usually, you can find these sources through Internet searches, but sometimes you may have difficulty determining their credibility.

Judging Credibility

To judge credibility, begin by looking for the author or organization publishing the information. Most periodical compositions contain a short “About the Author” blurb at the beginning or end of the article and often include a link to the author’s credentials or to more information about them. Using this information, you can begin to determine their expertise and, potentially, any agenda the author or organization may have. For example, expect a piece discussing side effects of medical marijuana written by a doctor to present more expertise than the same piece written by a political lobbyist. You also can determine whether bias is present; for example, the organization may promote a particular way of thinking or have an agenda that will influence the content and language of the composition. In general, look for articles written with neutral expertise.

The CRAAP Test

You may find the CRAAP test a helpful and easy-to-remember tool for testing credibility. This checklist provides you with a method for evaluating any source for both reliability and credibility. CRAAP stands for Currency, Relevance, Authority, Accuracy, and Purpose. The CRAAP test, as shown in Table 14.2 , includes questions that can be asked of any source.

Sources with Clear Bias or Unclear Authority

The final type of source encompasses nearly everything else. Although they cannot be considered credible or valid to support your argument or claims, these sources are not necessarily useless. Especially when you are compiling sources at the beginning of a project, those with clear bias or unclear authority can be useful as you explore all facets of a topic, including positions within an argument. These sources also can help you identify topics on which to base your search terms and can even point you toward more credible sources.

Locating Sources

Academic article databases are the best starting places for finding sources. There are too many databases to cover them all in this chapter, but you would be wise to familiarize yourself with those to which you have access through your school or program. For further information on databases, see The Research Process: Where to Look for Existing Sources . In the long run, this knowledge will save you a good deal of time and a possible headache.

You will want to start with your college library website, which includes access to sources paid for by your institution. As a student, you should be able to access these quickly and easily. Another popular and wide-ranging database is Google Scholar . Google Scholar is helpful for finding sources across a wide range of topics. One drawback, however, is that it catalogues nearly all disciplines, so the results can be vast and unfocused. Therefore, when using Google Scholar, be as specific as possible, and add your academic discipline as a keyword. For example, when searching for information on climate change, add the keyword “environment” or “politics” depending on your research angle; otherwise, the results will include all disciplines and potentially bury the articles you seek. Google Scholar also has a feature labeled “Cited by,” which shows you other papers that cite the article in their review of literature relate to the topic. Writing Process: Informing and Analyzing contains more information about focusing your searches. Like clues to a mystery, one search can lead you to a wealth of related articles.

When you are able to identify potential sources by reading their abstracts or using Google Scholar, you may at times land on a publisher’s website that requires you to pay to read the full article. When you find yourself in a situation such as this, record information about the article—author(s), article title, journal title, publication date. It is likely that you will be able to use your school’s database to access the article. For information about other databases, consult The Research Process: Where to Look for Existing Sources .

Just as writing is recursive , requiring you to go back and forth between different stages of the process, you will likely return to your annotated bibliography at different points. You may begin by looking for sources related to your topic, or you may choose or narrow your topic after an initial database search for sources. If your project has a variety of possible topics, you may even start with a current issue of a leading journal in the field, find an article that interests you, and use that article to shape your topic selection. As a bonus, you will have your first reputable source. Later, as you refine your thesis, reasoning, and evidence, you may find yourself returning to your search for sources. Consider this hypothetical situation: You are developing an argument that examines the risk factors of childhood trauma that surface in later life. As you analyze the data from your sources, it occurs to you to find out whether any documented correlation exists between early trauma and resilience. So you return to Google Scholar and your university’s academic database to find more research based on this idea in order to revise your analysis by adding the new viewpoint.

One difficulty may be homing in on the keywords that will lead you to the sources you need. At this point, sources from the last two categories discussed may come into play: short pieces from credible websites and newspapers and other texts with clear bias or unclear authority. Less credible sources may lead you to better ones, particularly if you can identify the keywords used in them and then apply those keywords within academic databases. For more on developing useful keywords, consult The Research Process: Where to Look for Existing Sources .

Boolean Operators

Keyword searches can become frustrating, either yielding so much information that it seems impossible to sort through or narrowing the search so much that you miss important potential sources. One way to remedy this situation is to become familiar with Boolean operators , the basis of mathematical sets and database logic. Rather than searching with natural language only, you can use these operators to focus your search. The three basic Boolean operators are AND , OR , and NOT . Using these operators helps you search by linking necessary information, excluding irrelevant information, and focusing information. For example, if you have some pieces of information from tertiary sources, you may be able to use Boolean operators to find additional useful sources. A search string such as artificial intelligence (title) AND Buiten (author) AND 2019 (year) can yield the exact journal source you need. Here is a brief review of how to use the three operators:

• Use AND to narrow search results and tell the database to include all search terms in finding sources. If you want to find sources that include all of the search terms entered, use the AND operator. In Figure 14.11 , the darkest blue triangular section in the center of the Venn diagram represents the result set for this search, including all three terms. In many databases, including Google, AND is implied between each word. To exclude AND, use quotation marks. For example, Google would translate the search term ethics artificial intelligence as ethics AND artificial AND intelligence . To make your phrases more specific, use the AND operator combined with quotation marks: “ethics” AND “artificial intelligence” .
• Use OR to connect two or more similar concepts and broaden your results, telling the search engine that any of your search terms can appear in the results it gives you. The Boolean operator OR is represented by Figure 14.12 . Using the OR operator gives you a very large set of results.
• Use NOT to exclude results from a search. This operator can help you narrow your search, telling the search engine to ignore names or words you do not want included in your results. For example, if you know you don’t want self-driving cars in your search results, you might search for “artificial intelligence” NOT “self-driving cars” .

Choosing Sources

Choosing sources to include in your annotated bibliography may seem overwhelming. However, if you can find a few good academic articles as a starting point, use them to guide your research. Academic articles are efficient, scrutinized by experts in their fields, and organized in ways that aid readers in identifying key findings that relate to their argument. The following tips will help you choose solid sources to guide your research:

• Look for relevant scholarly articles. Even the briefest Google search can yield an overwhelming amount of content. Sift through it by looking first through academic databases to find high-quality sources relevant to your research.
• Read abstracts. As you sift through scholarly articles, you can get a good idea of what each one is about by reading the abstract. It includes the findings and will show you in about 100 words whether the paper holds relevance to your research.
• Skim. Once you have determined that an article may be useful, skim each section to glean the information you need. Closer and more extensive reading can come later as you develop and support your argument.
• Avoid getting bogged down in technical information or industry-specific jargon. The benefit of reading peer-reviewed research is that you know the reviewers have determined it to be solidly constructed. Therefore, even if you don’t understand some portions completely, you can still feel confident about using relevant information from the article.
• Work smarter by using the research provided. Once you have identified an article that is helpful to your research, use it to find more like it. Search for other publications by the authors; researchers often spend much of their careers researching one overarching topic or theme. Use the review of literature to identify related articles that may add to your research. You can also use the article’s bibliography to find additional sources. Or reverse engineer the process: use article databases to find other articles that cite the article in their literature reviews.

Annotated Bibliographies

Welcome to the Purdue OWL

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

This handout provides information about annotated bibliographies in MLA, APA, and CMS.

Definitions

A bibliography is a list of sources (books, journals, Web sites, periodicals, etc.) one has used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited" depending on the style format you are using. A bibliography usually just includes the bibliographic information (i.e., the author, title, publisher, etc.).

An annotation is a summary and/or evaluation. Therefore, an annotated bibliography includes a summary and/or evaluation of each of the sources. Depending on your project or the assignment, your annotations may do one or more of the following.

For more help, see our handout on paraphrasing sources.

For more help, see our handouts on evaluating resources .

• Reflect : Once you've summarized and assessed a source, you need to ask how it fits into your research. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic?

Your annotated bibliography may include some of these, all of these, or even others. If you're doing this for a class, you should get specific guidelines from your instructor.

Why should I write an annotated bibliography?

To learn about your topic : Writing an annotated bibliography is excellent preparation for a research project. Just collecting sources for a bibliography is useful, but when you have to write annotations for each source, you're forced to read each source more carefully. You begin to read more critically instead of just collecting information. At the professional level, annotated bibliographies allow you to see what has been done in the literature and where your own research or scholarship can fit. To help you formulate a thesis: Every good research paper is an argument. The purpose of research is to state and support a thesis. So, a very important part of research is developing a thesis that is debatable, interesting, and current. Writing an annotated bibliography can help you gain a good perspective on what is being said about your topic. By reading and responding to a variety of sources on a topic, you'll start to see what the issues are, what people are arguing about, and you'll then be able to develop your own point of view.

To help other researchers : Extensive and scholarly annotated bibliographies are sometimes published. They provide a comprehensive overview of everything important that has been and is being said about that topic. You may not ever get your annotated bibliography published, but as a researcher, you might want to look for one that has been published about your topic.

The format of an annotated bibliography can vary, so if you're doing one for a class, it's important to ask for specific guidelines.

The bibliographic information : Generally, though, the bibliographic information of the source (the title, author, publisher, date, etc.) is written in either MLA or APA format. For more help with formatting, see our MLA handout . For APA, go here: APA handout .

The annotations: The annotations for each source are written in paragraph form. The lengths of the annotations can vary significantly from a couple of sentences to a couple of pages. The length will depend on the purpose. If you're just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need more space.

You can focus your annotations for your own needs. A few sentences of general summary followed by several sentences of how you can fit the work into your larger paper or project can serve you well when you go to draft.

How to Annotate an Article

Last Updated: September 26, 2023 Fact Checked

This article was co-authored by Emily Listmann, MA . Emily Listmann is a private tutor in San Carlos, California. She has worked as a Social Studies Teacher, Curriculum Coordinator, and an SAT Prep Teacher. She received her MA in Education from the Stanford Graduate School of Education in 2014. There are 9 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 398,425 times.

Annotating a text means that you take notes in the margins and make other markings for reading comprehension. Many people use annotation as part of academic research or to further their understanding of a certain work. To annotate an article, you'll need to ask questions as you go through the text, focus on themes, circle terms you don't understand, and write your opinions on the text's claims. You can annotate an article by hand or with an online note-taking program.

Following General Annotation Procedures

• Background on the author
• Themes throughout the text
• The author’s purpose for writing the text
• The author’s thesis
• Points of confusion
• How the text compares to other texts you are analyzing on the same topic
• Questions to ask your teacher or questions to bring up in class discussions

• Later on, you can gather all of these citations together to form a bibliography or works cited page, if required.
• If you are working with a source that frequently changes, such as a newspaper or website, make sure to mark down the accession date or number (the year the piece was acquired and/or where it came from).

• If you were given an assignment sheet with listed objectives, you might look over your completed annotation and check off each objective when finished. This will ensure that you’ve met all of the requirements.

• You can also write down questions that you plan to bring up during a class discussion. For example, you might write, “What does everyone think about this sentence?” Or, if your reading connects to a future writing assignment, you can ask questions that connect to that work.

• You could write, “Connects to the theme of hope and redemption discussed in class.”

• Use whatever symbol marking system works for you. Just make sure that you are consistent in your use of certain symbols.
• As you review your notes, you can create a list of all of the particular words that are circled. This may make it easier to look them up.
• For example, if the tone of the work changes mid-paragraph, you might write a question mark next to that section.

• To increase your reading comprehension even more, you might want to write down the thesis statement in the margins in your own words.
• The thesis sentence might start with a statement, such as, “I argue…”

• For example, reading online reviews can help you to determine whether or not the work is controversial or has been received without much fanfare.
• If there are multiple authors for the work, start by researching the first name listed.

• You might write, “This may contradict any earlier section.” Or, “I don’t agree with this.”

Annotating an Article by Hand

• You can also file away this paper copy for future reference as you continue your research.

• If you are visual learner, you might consider developing a notation system involving various colors of highlighters and flags.

• Depending on how you’ve taken your notes, you could also remove these Post-its to create an outline prior to writing.

• This rough annotation can then be used to create a larger annotated bibliography. This will help you to see any gaps in your research as well. [11] X Research source

Annotating an Article on a Webpage

• You could also use a program, such as Evernote, MarkUp.io, Bounce, Shared Copy, WebKlipper, or Springnote. Be aware that some of these programs may require a payment for access.

• Depending on your program, you may be able to respond to other people’s comments. You can also designate your notes as private or public.

Community Q&A

• Annotating takes extra time, so make sure to set aside enough time for you to complete your work. [15] X Research source Thanks Helpful 0 Not Helpful 0
• If traditional annotation doesn’t appeal to you, then create a dialectical journal where you write down any quotes that speak to you. Thanks Helpful 0 Not Helpful 0

• If you end up integrating your notes into a written project, make sure to keep your citation information connected. Otherwise, you run the risk of committing plagiarism. Thanks Helpful 0 Not Helpful 0

About This Article

To annotate an article, start by underlining the thesis, or the main argument that the author is making. Next, underline the topic sentences for each paragraph to help you focus on the themes throughout the text.

What is an Annotated Bibliogrphy?

An annotated bibliography is a list of citations followed by a brief (usually about 150 words) evaluative paragraph called an annotation. Essentially, it is a works cited or reference list with additional information about each source. Make sure to follow the citation format your instructor requires! (MLA, APA, Chicago, etc.)

Your annotation can include a sentences answering the following questions:

• Summarize : Some annotations merely summarize the source. What are the main arguments? What is the point of this book or article? What topics are covered? If someone asked what this article/book is about, what would you say? The length of your annotations will determine how detailed your summary is.
• Assess : After summarizing a source, it may be helpful to evaluate it. Is it a useful source? How does it compare with other sources in your bibliography? Is the information reliable? Is this source biased or objective? What is the goal of this source?
• Reflect : Once you've summarized and assessed a source, you need to ask how it fits into your research. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic?

Designing Research in Education: Concepts and Methodologies

Student resources, annotated research proposals.

Downloadable annotated research proposals written by post-graduate students.

Comments down the side will help readers critically engage with the texts and see how the markers (or reviewers) arrived at their judgments, showing readers what criteria is used to call a proposal ‘good’ or ‘weak’. In order to anonymise the work, the students are referred to as either ‘the writer’, ‘author’ or ‘researcher’.

For masters or doctoral work, proposals should often be regarded as being organic and provisional; they do not have to be set in stone and many (particularly with more inductive designs) will have flexible designs (see Proposal 3) and will undergo considerable change. However, if students want to make a professional career as an academic they will often need to develop the skills to be able to write ‘excellent’ proposals in order to secure research funding.

Research Proposal 1

Written as a course assignment and awarded a grade A.

Around 2,500 words long, excluding references.

Research Proposal 2

Written as a course assignment and given a C.

Research Proposal 3

An example of a successful application for a three-year funded project to the ESRC (a major funding body in the UK).

ESRC proposals are restricted to four sides of A4.

Even before complaints about X’s declining quality, posting a paper on the social-media platform did not lead to a boost in citations. Credit: Matt Cardy/Getty

Posting about a research paper on social-media platform X (formerly known as Twitter) doesn’t translate into a bump in citations, according to a study that looked at 550 papers.
