How to Find Sources | Scholarly Articles, Books, Etc.

Published on June 13, 2022 by Eoghan Ryan . Revised on May 31, 2023.

It’s important to know how to find relevant sources when writing a  research paper , literature review , or systematic review .

The types of sources you need will depend on the stage you are at in the research process , but all sources that you use should be credible , up to date, and relevant to your research topic.

There are three main places to look for sources to use in your research:

Research databases

• Your institution’s library
• Other online resources

Table of contents

Library resources, other online sources, other interesting articles, frequently asked questions about finding sources.

You can search for scholarly sources online using databases and search engines like Google Scholar . These provide a range of search functions that can help you to find the most relevant sources.

If you are searching for a specific article or book, include the title or the author’s name. Alternatively, if you’re just looking for sources related to your research problem , you can search using keywords. In this case, it’s important to have a clear understanding of the scope of your project and of the most relevant keywords.

Databases can be general (interdisciplinary) or subject-specific.

• You can use subject-specific databases to ensure that the results are relevant to your field.
• When using a general database or search engine, you can still filter results by selecting specific subjects or disciplines.

Example: JSTOR discipline search filter

Check the table below to find a database that’s relevant to your research.

Google Scholar

To get started, you might also try Google Scholar , an academic search engine that can help you find relevant books and articles. Its “Cited by” function lets you see the number of times a source has been cited. This can tell you something about a source’s credibility and importance to the field.

Example: Google Scholar “Cited by” function

Boolean operators

Boolean operators can also help to narrow or expand your search.

Boolean operators are words and symbols like AND , OR , and NOT that you can use to include or exclude keywords to refine your results. For example, a search for “Nietzsche NOT nihilism” will provide results that include the word “Nietzsche” but exclude results that contain the word “nihilism.”

Many databases and search engines have an advanced search function that allows you to refine results in a similar way without typing the Boolean operators manually.

Example: Project Muse advanced search

You can find helpful print sources in your institution’s library. These include:

• Journal articles
• Encyclopedias
• Newspapers and magazines

Make sure that the sources you consult are appropriate to your research.

You can find these sources using your institution’s library database. This will allow you to explore the library’s catalog and to search relevant keywords. You can refine your results using Boolean operators .

Once you have found a relevant print source in the library:

• Consider what books are beside it. This can be a great way to find related sources, especially when you’ve found a secondary or tertiary source instead of a primary source .
• Consult the index and bibliography to find the bibliographic information of other relevant sources.

You can consult popular online sources to learn more about your topic. These include:

• Crowdsourced encyclopedias like Wikipedia

You can find these sources using search engines. To refine your search, use Boolean operators in combination with relevant keywords.

However, exercise caution when using online sources. Consider what kinds of sources are appropriate for your research and make sure the sites are credible .

Look for sites with trusted domain extensions:

• URLs that end with .edu are educational resources.
• URLs that end with .gov are government-related resources.
• DOIs often indicate that an article is published in a peer-reviewed , scientific article.

Other sites can still be used, but you should evaluate them carefully and consider alternatives.

You can find sources online using databases and search engines like Google Scholar . Use Boolean operators or advanced search functions to narrow or expand your search.

For print sources, you can use your institution’s library database. This will allow you to explore the library’s catalog and to search relevant keywords.

It is important to find credible sources and use those that you can be sure are sufficiently scholarly .

• Consult your institute’s library to find out what books, journals, research databases, and other types of sources they provide access to.
• Look for books published by respected academic publishing houses and university presses, as these are typically considered trustworthy sources.
• Look for journals that use a peer review process. This means that experts in the field assess the quality and credibility of an article before it is published.

When searching for sources in databases, think of specific keywords that are relevant to your topic , and consider variations on them or synonyms that might be relevant.

Once you have a clear idea of your research parameters and key terms, choose a database that is relevant to your research (e.g., Medline, JSTOR, Project MUSE).

Find out if the database has a “subject search” option. This can help to refine your search. Use Boolean operators to combine your keywords, exclude specific search terms, and search exact phrases to find the most relevant sources.

There are many types of sources commonly used in research. These include:

You’ll likely use a variety of these sources throughout the research process , and the kinds of sources you use will depend on your research topic and goals.

Scholarly sources are written by experts in their field and are typically subjected to peer review . They are intended for a scholarly audience, include a full bibliography, and use scholarly or technical language. For these reasons, they are typically considered credible sources .

Popular sources like magazines and news articles are typically written by journalists. These types of sources usually don’t include a bibliography and are written for a popular, rather than academic, audience. They are not always reliable and may be written from a biased or uninformed perspective, but they can still be cited in some contexts.

21 Legit Research Databases for Free Journal Articles in 2022

#scribendiinc

Written by  Scribendi

Has this ever happened to you? While looking for websites for research, you come across a research paper site that claims to connect academics to a peer-reviewed article database for free.

Intrigued, you search for keywords related to your topic, only to discover that you must pay a hefty subscription fee to access the service. After the umpteenth time being duped, you begin to wonder if there's even such a thing as free journal articles .

Subscription fees and paywalls are often the bane of students and academics, especially those at small institutions who don't provide access to many free article directories and repositories.

Whether you're working on an undergraduate paper, a PhD dissertation, or a medical research study, we want to help you find tools to locate and access the information you need to produce well-researched, compelling, and innovative work.

Below, we discuss why peer-reviewed articles are superior and list out the best free article databases to use in 2022.

Why peer-reviewed scholarly journal articles are more authoritative.

Determining what sources are reliable can be challenging. Peer-reviewed scholarly journal articles are the gold standard in academic research. Reputable academic journals have a rigorous peer-review process.

The peer review process provides accountability to the academic community, as well as to the content of the article. The peer review process involves qualified experts in a specific (often very specific) field performing a review of an article's methods and findings to determine things like quality and credibility.

Peer-reviewed articles can be found in peer-reviewed article databases and research databases, and if you know that a database of journals is reliable, that can offer reassurances about the reliability of a free article. Peer review is often double blind, meaning that the author removes all identifying information and, likewise, does not know the identity of the reviewers. This helps reviewers maintain objectivity and impartiality so as to judge an article based on its merit.

Where to Find Peer-Reviewed Articles

Peer-reviewed articles can be found in a variety of research databases. Below is a list of some of the major databases you can use to find peer-reviewed articles and other sources in disciplines spanning the humanities, sciences, and social sciences.

What Are Open Access Journals?

An open access (OA) journal is a journal whose content can be accessed without payment. This provides scholars, students, and researchers with free journal articles . OA journals use alternate methods of funding to cover publication costs so that articles can be published without having to pass those publication costs on to the reader.

Some of these funding models include standard funding methods like advertising, public funding, and author payment models, where the author pays a fee in order to publish in the journal. There are OA journals that have non-peer-reviewed academic content, as well as journals that focus on dissertations, theses, and papers from conferences, but the main focus of OA is peer-reviewed scholarly journal articles.

The internet has certainly made it easier to access research articles and other scholarly publications without needing access to a university library, and OA takes another step in that direction by removing financial barriers to academic content.

Choosing Wisely

Features of legitimate oa journals.

 There are things to look out for when trying to decide if a free publication journal is legitimate:

Mission statement —The mission statement for an OA journal should be available on their website.

Publication history —Is the journal well established? How long has it been available?

Editorial board —Who are the members of the editorial board, and what are their credentials?

Indexing —Can the journal be found in a reliable database?

Peer review —What is the peer review process? Does the journal allow enough time in the process for a reliable assessment of quality?

Impact factor —What is the average number of times the journal is cited over a two-year period?

Features of Illegitimate OA Journals

There are predatory publications that take advantage of the OA format, and they are something to be wary of. Here are some things to look out for:

Contact information —Is contact information provided? Can it be verified?

Turnaround —If the journal makes dubious claims about the amount of time from submission to publication, it is likely unreliable.

Editorial board —Much like determining legitimacy, looking at the editorial board and their credentials can help determine illegitimacy.

Indexing —Can the journal be found in any scholarly databases?

Peer review —Is there a statement about the peer review process? Does it fit what you know about peer review?

How to Find Scholarly Articles

Identify keywords.

Keywords are included in an article by the author. Keywords are an excellent way to find content relevant to your research topic or area of interest. In academic searches, much like you would on a search engine, you can use keywords to navigate through what is available to find exactly what you're looking for.

Authors provide keywords that will help you easily find their article when researching a related topic, often including general terms to accommodate broader searches, as well as some more specific terms for those with a narrower scope. Keywords can be used individually or in combination to refine your scholarly article search.

Narrow Down Results

Sometimes, search results can be overwhelming, and searching for free articles on a journal database is no exception, but there are multiple ways to narrow down your results. A good place to start is discipline.

What category does your topic fall into (psychology, architecture, machine learning, etc.)? You can also narrow down your search with a year range if you're looking for articles that are more recent.

A Boolean search can be incredibly helpful. This entails including terms like AND between two keywords in your search if you need both keywords to be in your results (or, if you are looking to exclude certain keywords, to exclude these words from the results).

Consider Different Avenues

If you're not having luck using keywords in your search for free articles, you may still be able to find what you're looking for by changing your tactics. Casting a wider net sometimes yields positive results, so it may be helpful to try searching by subject if keywords aren't getting you anywhere.

You can search for a specific publisher to see if they have OA publications in the academic journal database. And, if you know more precisely what you're looking for, you can search for the title of the article or the author's name.

How to find peer-reviewed articles.

There are a lot of free scholarly articles available from various sources. The internet is a big place. So how do you go about finding peer-reviewed articles when conducting your research? It's important to make sure you are using reputable sources.

The first source of the article is the person or people who wrote it. Checking out the author can give you some initial insight into how much you can trust what you’re reading. Looking into the publication information of your sources can also indicate whether the article is reliable.

Aspects of the article, such as subject and audience, tone, and format, are other things you can look at when evaluating whether the article you're using is valid, reputable, peer-reviewed material. So, let's break that down into various components so you can assess your research to ensure that you're using quality articles and conducting solid research.

Check the Author

Peer-reviewed articles are written by experts or scholars with experience in the field or discipline they're writing about. The research in a peer-reviewed article has to pass a rigorous evaluation process, so it’s a foregone conclusion that the author(s) of a peer-reviewed article should have experience or training related to that research.

When evaluating an article, take a look at the author’s information. What credentials does the author have to indicate that their research has scholarly weight behind it? Finding out what type of degree the author has—and what that degree is in—can provide insight into what kind of authority the author is on the subject.

Something else that might lend credence to the author’s scholarly role is their professional affiliation. A look at what organization or institution they are affiliated with can tell you a lot about their experience or expertise. Where were they trained, and who is verifying their research?

Identify Subject and Audience

The ultimate goal of a study is to answer a question. Scholarly articles are also written for scholarly audiences, especially articles that have gone through the peer review process. This means that the author is trying to reach experts, researchers, academics, and students in the field or topic the research is based on.

Think about the question the author is trying to answer by conducting this research, why, and for whom. What is the subject of the article? What question has it set out to answer? What is the purpose of finding the information? Is the purpose of the article of importance to other scholars? Is it original content?

Research should also be approached analytically. Is the methodology sound? Is the author using an analytical approach to evaluate the data that they have obtained? Are the conclusions they've reached substantiated by their data and analysis? Answering these questions can reveal a lot about the article’s validity.

Format Matters

Reliable articles from peer-reviewed sources have certain format elements to be aware of. The first is an abstract. An abstract is a short summary or overview of the article. Does the article have an abstract? It's unlikely that you're reading a peer-reviewed article if it doesn’t. Peer-reviewed journals will also have a word count range. If an article seems far too short or incredibly long, that may be reason to doubt it.

Another feature of reliable articles is the sections the information is divided into. Peer-reviewed research articles will have clear, concise sections that appropriately organize the information. This might include a literature review, methodology, and results in the case of research articles and a conclusion.

One of the most important sections is the references or bibliography. This is where the researcher lists all the sources of their information. A peer-reviewed source will have a comprehensive reference section.

An article that has been written to reach an academic community will have an academic tone. The language that is used, and the way this language is used, is important to consider. If the article is riddled with grammatical errors, confusing syntax, and casual language, it almost definitely didn't make it through the peer review process.

Also consider the use of terminology. Every discipline is going to have standard terminology or jargon that can be used and understood by other academics in the discipline. The language in a peer-reviewed article is going to reflect that.

If the author is going out of their way to explain simple terms, or terms that are standard to the field or discipline, it's unlikely that the article has been peer reviewed, as this is something that the author would be asked to address during the review process.

Publication

The source of the article will be a very good indicator of the likelihood that it was peer reviewed. Where was the article published? Was it published alongside other academic articles in the same discipline? Is it a legitimate and reputable scholarly publication?

A trade publication or newspaper might be legitimate or reputable, but it is not a scholarly source, and it will not have been subject to the peer review process. Scholarly journals are the best resource for peer-reviewed articles, but it's important to remember that not all scholarly journals are peer reviewed.

It’s helpful to look at a scholarly source’s website, as peer-reviewed journals will have a clear indication of the peer review process. University libraries, institutional repositories, and reliable databases (and you now might have a list of some legit ones) can also help provide insight into whether an article comes from a peer-reviewed journal.

Common Research Mistakes to Avoid

Research is a lot of work. Even with high standards and good intentions, it’s easy to make mistakes. Perhaps you searched for access to scientific journals for free and found the perfect peer-reviewed sources, but you forgot to document everything, and your references are a mess. Or, you only searched for free online articles and missed out on a ground-breaking study that was behind a paywall.

Whether your research is for a degree or to get published or to satisfy your own inquisitive nature, or all of the above, you want all that work to produce quality results. You want your research to be thorough and accurate.

To have any hope of contributing to the literature on your research topic, your results need to be high quality. You might not be able to avoid every potential mistake, but here are some that are both common and easy to avoid.

Sticking to One Source

One of the hallmarks of good research is a healthy reference section. Using a variety of sources gives you a better answer to your question. Even if all of the literature is in agreement, looking at various aspects of the topic may provide you with an entirely different picture than you would have if you looked at your research question from only one angle.

Not Documenting Every Fact

As you conduct your research, do yourself a favor and write everything down. Everything you include in your paper or article that you got from another source is going to need to be added to your references and cited.

It's important, especially if your aim is to conduct ethical, high-quality research, that all of your research has proper attribution. If you don't document as you go, you could end up making a lot of work for yourself if the information you don’t write down is something that later, as you write your paper, you really need.

Using Outdated Materials

Academia is an ever-changing landscape. What was true in your academic discipline or area of research ten years ago may have since been disproven. If fifteen studies have come out since the article that you're using was published, it's more than a little likely that you're going to be basing your research on flawed or dated information.

If the information you're basing your research on isn’t as up-to-date as possible, your research won't be of quality or able to stand up to any amount of scrutiny. You don’t want all of your hard work to be for naught.

Relying Solely on Open Access Journals

OA is a great resource for conducting academic research. There are high-quality journal articles available through OA, and that can be very helpful for your research. But, just because you have access to free articles, that doesn't mean that there's nothing to be found behind a paywall.

Just as dismissing high-quality peer-reviewed articles because they are OA would be limiting, not exploring any paid content at all is equally short-sighted. If you're seeking to conduct thorough and comprehensive research, exploring all of your options for quality sources is going to be to your benefit.

Digging Too Deep or Not Deep Enough

Research is an art form, and it involves a delicate balance of information. If you conduct your research using only broad search terms, you won't be able to answer your research question well, or you'll find that your research provides information that is closely related to your topic but, ultimately, your findings are vague and unsubstantiated.

On the other hand, if you delve deeply into your research topic with specific searches and turn up too many sources, you might have a lot of information that is adjacent to your topic but without focus and perhaps not entirely relevant. It's important to answer your research question concisely but thoroughly.

Different Types of Scholarly Articles

Different types of scholarly articles have different purposes. An original research article, also called an empirical article, is the product of a study or an experiment. This type of article seeks to answer a question or fill a gap in the existing literature.

Research articles will have a methodology, results, and a discussion of the findings of the experiment or research and typically a conclusion.

Review articles overview the current literature and research and provide a summary of what the existing research indicates or has concluded. This type of study will have a section for the literature review, as well as a discussion of the findings of that review. Review articles will have a particularly extensive reference or bibliography section.

Theoretical articles draw on existing literature to create new theories or conclusions, or look at current theories from a different perspective, to contribute to the foundational knowledge of the field of study.

10 Tips for Navigating Journal Databases

Use the right academic journal database for your search, be that interdisciplinary or specific to your field. Or both!

If it’s an option, set the search results to return only peer-reviewed sources.

Start by using search terms that are relevant to your topic without being overly specific.

Try synonyms, especially if your keywords aren’t returning the desired results.

Even if you’ve found some good articles, try searching using different terms.

Explore the advanced search features of the database(s).

Learn to use Booleans (AND, OR, NOT) to expand or narrow your results.

Once you’ve gotten some good results from a more general search, try narrowing your search.

Read through abstracts when trying to find articles relevant to your research.

Keep track of your research and use citation tools. It’ll make life easier when it comes time to compile your references.

7 Frequently Asked Questions

1. how do i get articles for free.

Free articles can be found through free online academic journals, OA databases, or other databases that include OA journals and articles. These resources allow you to access free papers online so you can conduct your research without getting stuck behind a paywall.

Academics don’t receive payment for the articles they contribute to journals. There are often, in fact, publication fees that scholars pay in order to publish. This is one of the funding structures that allows OA journals to provide free content so that you don’t have to pay fees or subscription costs to access journal articles.

2. How Do I Find Journal Articles?

Journal articles can be found in databases and institutional repositories that can be accessed at university libraries. However, online research databases that contain OA articles are the best resource for getting free access to journal articles that are available online.

Peer-reviewed journal articles are the best to use for academic research, and there are a number of databases where you can find peer-reviewed OA journal articles. Once you've found a useful article, you can look through the references for the articles the author used to conduct their research, and you can then search online databases for those articles, too.

3. How Do I Find Peer-Reviewed Articles?

Peer-reviewed articles can be found in reputable scholarly peer-reviewed journals. High-quality journals and journal articles can be found online using academic search engines and free research databases. These resources are excellent for finding OA articles, including peer-reviewed articles.

OA articles are articles that can be accessed for free. While some scholarly search engines and databases include articles that aren't peer reviewed, there are also some that provide only peer-reviewed articles, and databases that include non-peer-reviewed articles often have advanced search features that enable you to select “peer review only.” The database will return results that are exclusively peer-reviewed content.

4. What Are Research Databases?

A research database is a list of journals, articles, datasets, and/or abstracts that allows you to easily search for scholarly and academic resources and conduct research online. There are databases that are interdisciplinary and cover a variety of topics.

For example, Paperity might be a great resource for a chemist as well as a linguist, and there are databases that are more specific to a certain field. So, while ERIC might be one of the best educational databases available for OA content, it's not going to be one of the best databases for finding research in the field of microbiology.

5. How Do I Find Scholarly Articles for Specific Fields?

There are interdisciplinary research databases that provide articles in a variety of fields, as well as research databases that provide articles that cater to specific disciplines. Additionally, a journal repository or index can be a helpful resource for finding articles in a specific field.

When searching an interdisciplinary database, there are frequently advanced search features that allow you to narrow the search results down so that they are specific to your field. Selecting “psychology” in the advanced search features will return psychology journal articles in your search results. You can also try databases that are specific to your field.

If you're searching for law journal articles, many law reviews are OA. If you don’t know of any databases specific to history, visiting a journal repository or index and searching “history academic journals” can return a list of journals specific to history and provide you with a place to begin your research.

6. Are Peer-Reviewed Articles Really More Legitimate?

The short answer is yes, peer-reviewed articles are more legitimate resources for academic research. The peer review process provides legitimacy, as it is a rigorous review of the content of an article that is performed by scholars and academics who are experts in their field of study. The review provides an evaluation of the quality and credibility of the article.

Non-peer-reviewed articles are not subject to a review process and do not undergo the same level of scrutiny. This means that non-peer-reviewed articles are unlikely, or at least not as likely, to meet the same standards that peer-reviewed articles do.

7. Are Free Article Directories Legitimate?

Yes! As with anything, some databases are going to be better for certain requirements than others. But, a scholarly article database being free is not a reason in itself to question its legitimacy.

Free scholarly article databases can provide access to abstracts, scholarly article websites, journal repositories, and high-quality peer-reviewed journal articles. The internet has a lot of information, and it's often challenging to figure out what information is reliable. 

Research databases and article directories are great resources to help you conduct your research. Our list of the best research paper websites is sure to provide you with sources that are totally legit.

What's a Scholarly Article?

Your professor has specified that you are to use scholarly (or primary research or peer-reviewed or refereed or academic) articles only in your paper. What does that mean?

Scholarly or primary research articles are peer-reviewed , which means that they have gone through the process of being read by reviewers or referees  before being accepted for publication. When a scholar submits an article to a scholarly journal, the manuscript is sent to experts in that field to read and decide if the research is valid and the article should be published. Typically the reviewers indicate to the journal editors whether they think the article should be accepted, sent back for revisions, or rejected.

To decide whether an article is a primary research article, look for the following:

• The author’s (or authors') credentials and academic affiliation(s) should be given;
• There should be an abstract summarizing the research;
• The methods and materials used should be given, often in a separate section;
• There are citations within the text or footnotes referencing sources used;
• Results of the research are given;
• There should be discussion   and  conclusion ;
• With a bibliography or list of references at the end.

Caution: even though a journal may be peer-reviewed, not all the items in it will be. For instance, there might be editorials, book reviews, news reports, etc. Check for the parts of the article to be sure.   

You can limit your search results to primary research, peer-reviewed or refereed articles in many databases. To search for scholarly articles in  HOLLIS , type your keywords in the box at the top, and select  Catalog&Articles  from the choices that appear next.   On the search results screen, look for the  Show Only section on the right and click on  Peer-reviewed articles . (Make sure to  login in with your HarvardKey to get full-text of the articles that Harvard has purchased.)

Many of the databases that Harvard offers have similar features to limit to peer-reviewed or scholarly articles.  For example in Academic Search Premier , click on the box for Scholarly (Peer Reviewed) Journals  on the search screen.

Review articles are another great way to find scholarly primary research articles.   Review articles are not considered "primary research", but they pull together primary research articles on a topic, summarize and analyze them.  In Google Scholar , click on Review Articles  at the left of the search results screen. Ask your professor whether review articles can be cited for an assignment.

A note about Google searching.  A regular Google search turns up a broad variety of results, which can include scholarly articles but Google results also contain commercial and popular sources which may be misleading, outdated, etc.  Use Google Scholar  through the Harvard Library instead.

About Wikipedia .  W ikipedia is not considered scholarly, and should not be cited, but it frequently includes references to scholarly articles. Before using those references for an assignment, double check by finding them in Hollis or a more specific subject  database .

Still not sure about a source? Consult the course syllabus for guidance, contact your professor or teaching fellow, or use the Ask A Librarian service.

Get the most out of Google Scholar with some helpful tips on searches, email alerts, citation export, and more.

Finding recent papers

Your search results are normally sorted by relevance, not by date. To find newer articles, try the following options in the left sidebar:

• click "Since Year" to show only recently published papers, sorted by relevance;
• click "Sort by date" to show just the new additions, sorted by date;
• click the envelope icon to have new results periodically delivered by email.

Locating the full text of an article

Abstracts are freely available for most of the articles. Alas, reading the entire article may require a subscription. Here're a few things to try:

• click a library link, e.g., "FindIt@Harvard", to the right of the search result;
• click a link labeled [PDF] to the right of the search result;
• click "All versions" under the search result and check out the alternative sources;
• click "Related articles" or "Cited by" under the search result to explore similar articles.

If you're affiliated with a university, but don't see links such as "FindIt@Harvard", please check with your local library about the best way to access their online subscriptions. You may need to do search from a computer on campus, or to configure your browser to use a library proxy.

Getting better answers

If you're new to the subject, it may be helpful to pick up the terminology from secondary sources. E.g., a Wikipedia article for "overweight" might suggest a Scholar search for "pediatric hyperalimentation".

If the search results are too specific for your needs, check out what they're citing in their "References" sections. Referenced works are often more general in nature.

Similarly, if the search results are too basic for you, click "Cited by" to see newer papers that referenced them. These newer papers will often be more specific.

Explore! There's rarely a single answer to a research question. Click "Related articles" or "Cited by" to see closely related work, or search for author's name and see what else they have written.

Searching Google Scholar

Use the "author:" operator, e.g., author:"d knuth" or author:"donald e knuth".

Put the paper's title in quotations: "A History of the China Sea".

You'll often get better results if you search only recent articles, but still sort them by relevance, not by date. E.g., click "Since 2018" in the left sidebar of the search results page.

To see the absolutely newest articles first, click "Sort by date" in the sidebar. If you use this feature a lot, you may also find it useful to setup email alerts to have new results automatically sent to you.

Note: On smaller screens that don't show the sidebar, these options are available in the dropdown menu labelled "Year" right below the search button.

Select the "Case law" option on the homepage or in the side drawer on the search results page.

It finds documents similar to the given search result.

It's in the side drawer. The advanced search window lets you search in the author, title, and publication fields, as well as limit your search results by date.

Select the "Case law" option and do a keyword search over all jurisdictions. Then, click the "Select courts" link in the left sidebar on the search results page.

Tip: To quickly search a frequently used selection of courts, bookmark a search results page with the desired selection.

Access to articles

For each Scholar search result, we try to find a version of the article that you can read. These access links are labelled [PDF] or [HTML] and appear to the right of the search result. For example:

A paper that you need to read

Access links cover a wide variety of ways in which articles may be available to you - articles that your library subscribes to, open access articles, free-to-read articles from publishers, preprints, articles in repositories, etc.

When you are on a campus network, access links automatically include your library subscriptions and direct you to subscribed versions of articles. On-campus access links cover subscriptions from primary publishers as well as aggregators.

Off-campus access

Off-campus access links let you take your library subscriptions with you when you are at home or traveling. You can read subscribed articles when you are off-campus just as easily as when you are on-campus. Off-campus access links work by recording your subscriptions when you visit Scholar while on-campus, and looking up the recorded subscriptions later when you are off-campus.

We use the recorded subscriptions to provide you with the same subscribed access links as you see on campus. We also indicate your subscription access to participating publishers so that they can allow you to read the full-text of these articles without logging in or using a proxy. The recorded subscription information expires after 30 days and is automatically deleted.

In addition to Google Scholar search results, off-campus access links can also appear on articles from publishers participating in the off-campus subscription access program. Look for links labeled [PDF] or [HTML] on the right hand side of article pages.

You can disable off-campus access links on the Scholar settings page . Disabling off-campus access links will turn off recording of your library subscriptions. It will also turn off indicating subscription access to participating publishers. Once off-campus access links are disabled, you may need to identify and configure an alternate mechanism (e.g., an institutional proxy or VPN) to access your library subscriptions while off-campus.

Email Alerts

Do a search for the topic of interest, e.g., "M Theory"; click the envelope icon in the sidebar of the search results page; enter your email address, and click "Create alert". We'll then periodically email you newly published papers that match your search criteria.

No, you can enter any email address of your choice. If the email address isn't a Google account or doesn't match your Google account, then we'll email you a verification link, which you'll need to click to start receiving alerts.

This works best if you create a public profile , which is free and quick to do. Once you get to the homepage with your photo, click "Follow" next to your name, select "New citations to my articles", and click "Done". We will then email you when we find new articles that cite yours.

Search for the title of your paper, e.g., "Anti de Sitter space and holography"; click on the "Cited by" link at the bottom of the search result; and then click on the envelope icon in the left sidebar of the search results page.

First, do a search for your colleague's name, and see if they have a Scholar profile. If they do, click on it, click the "Follow" button next to their name, select "New articles by this author", and click "Done".

If they don't have a profile, do a search by author, e.g., [author:s-hawking], and click on the mighty envelope in the left sidebar of the search results page. If you find that several different people share the same name, you may need to add co-author names or topical keywords to limit results to the author you wish to follow.

We send the alerts right after we add new papers to Google Scholar. This usually happens several times a week, except that our search robots meticulously observe holidays.

There's a link to cancel the alert at the bottom of every notification email.

If you created alerts using a Google account, you can manage them all here . If you're not using a Google account, you'll need to unsubscribe from the individual alerts and subscribe to the new ones.

Google Scholar library

Google Scholar library is your personal collection of articles. You can save articles right off the search page, organize them by adding labels, and use the power of Scholar search to quickly find just the one you want - at any time and from anywhere. You decide what goes into your library, and we’ll keep the links up to date.

You get all the goodies that come with Scholar search results - links to PDF and to your university's subscriptions, formatted citations, citing articles, and more!

Library help

Find the article you want to add in Google Scholar and click the “Save” button under the search result.

Click “My library” at the top of the page or in the side drawer to view all articles in your library. To search the full text of these articles, enter your query as usual in the search box.

Find the article you want to remove, and then click the “Delete” button under it.

• To add a label to an article, find the article in your library, click the “Label” button under it, select the label you want to apply, and click “Done”.
• To view all the articles with a specific label, click the label name in the left sidebar of your library page.
• To remove a label from an article, click the “Label” button under it, deselect the label you want to remove, and click “Done”.
• To add, edit, or delete labels, click “Manage labels” in the left column of your library page.

Only you can see the articles in your library. If you create a Scholar profile and make it public, then the articles in your public profile (and only those articles) will be visible to everyone.

Your profile contains all the articles you have written yourself. It’s a way to present your work to others, as well as to keep track of citations to it. Your library is a way to organize the articles that you’d like to read or cite, not necessarily the ones you’ve written.

Citation Export

Click the "Cite" button under the search result and then select your bibliography manager at the bottom of the popup. We currently support BibTeX, EndNote, RefMan, and RefWorks.

Err, no, please respect our robots.txt when you access Google Scholar using automated software. As the wearers of crawler's shoes and webmaster's hat, we cannot recommend adherence to web standards highly enough.

Sorry, we're unable to provide bulk access. You'll need to make an arrangement directly with the source of the data you're interested in. Keep in mind that a lot of the records in Google Scholar come from commercial subscription services.

Sorry, we can only show up to 1,000 results for any particular search query. Try a different query to get more results.

Content Coverage

Google Scholar includes journal and conference papers, theses and dissertations, academic books, pre-prints, abstracts, technical reports and other scholarly literature from all broad areas of research. You'll find works from a wide variety of academic publishers, professional societies and university repositories, as well as scholarly articles available anywhere across the web. Google Scholar also includes court opinions and patents.

We index research articles and abstracts from most major academic publishers and repositories worldwide, including both free and subscription sources. To check current coverage of a specific source in Google Scholar, search for a sample of their article titles in quotes.

While we try to be comprehensive, it isn't possible to guarantee uninterrupted coverage of any particular source. We index articles from sources all over the web and link to these websites in our search results. If one of these websites becomes unavailable to our search robots or to a large number of web users, we have to remove it from Google Scholar until it becomes available again.

Our meticulous search robots generally try to index every paper from every website they visit, including most major sources and also many lesser known ones.

That said, Google Scholar is primarily a search of academic papers. Shorter articles, such as book reviews, news sections, editorials, announcements and letters, may or may not be included. Untitled documents and documents without authors are usually not included. Website URLs that aren't available to our search robots or to the majority of web users are, obviously, not included either. Nor do we include websites that require you to sign up for an account, install a browser plugin, watch four colorful ads, and turn around three times and say coo-coo before you can read the listing of titles scanned at 10 DPI... You get the idea, we cover academic papers from sensible websites.

That's usually because we index many of these papers from other websites, such as the websites of their primary publishers. The "site:" operator currently only searches the primary version of each paper.

It could also be that the papers are located on examplejournals.gov, not on example.gov. Please make sure you're searching for the "right" website.

That said, the best way to check coverage of a specific source is to search for a sample of their papers using the title of the paper.

Ahem, we index papers, not journals. You should also ask about our coverage of universities, research groups, proteins, seminal breakthroughs, and other dimensions that are of interest to users. All such questions are best answered by searching for a statistical sample of papers that has the property of interest - journal, author, protein, etc. Many coverage comparisons are available if you search for [allintitle:"google scholar"], but some of them are more statistically valid than others.

Currently, Google Scholar allows you to search and read published opinions of US state appellate and supreme court cases since 1950, US federal district, appellate, tax and bankruptcy courts since 1923 and US Supreme Court cases since 1791. In addition, it includes citations for cases cited by indexed opinions or journal articles which allows you to find influential cases (usually older or international) which are not yet online or publicly available.

Legal opinions in Google Scholar are provided for informational purposes only and should not be relied on as a substitute for legal advice from a licensed lawyer. Google does not warrant that the information is complete or accurate.

We normally add new papers several times a week. However, updates to existing records take 6-9 months to a year or longer, because in order to update our records, we need to first recrawl them from the source website. For many larger websites, the speed at which we can update their records is limited by the crawl rate that they allow.

Inclusion and Corrections

We apologize, and we assure you the error was unintentional. Automated extraction of information from articles in diverse fields can be tricky, so an error sometimes sneaks through.

Please write to the owner of the website where the erroneous search result is coming from, and encourage them to provide correct bibliographic data to us, as described in the technical guidelines . Once the data is corrected on their website, it usually takes 6-9 months to a year or longer for it to be updated in Google Scholar. We appreciate your help and your patience.

If you can't find your papers when you search for them by title and by author, please refer your publisher to our technical guidelines .

You can also deposit your papers into your institutional repository or put their PDF versions on your personal website, but please follow your publisher's requirements when you do so. See our technical guidelines for more details on the inclusion process.

We normally add new papers several times a week; however, it might take us some time to crawl larger websites, and corrections to already included papers can take 6-9 months to a year or longer.

Google Scholar generally reflects the state of the web as it is currently visible to our search robots and to the majority of users. When you're searching for relevant papers to read, you wouldn't want it any other way!

If your citation counts have gone down, chances are that either your paper or papers that cite it have either disappeared from the web entirely, or have become unavailable to our search robots, or, perhaps, have been reformatted in a way that made it difficult for our automated software to identify their bibliographic data and references. If you wish to correct this, you'll need to identify the specific documents with indexing problems and ask your publisher to fix them. Please refer to the technical guidelines .

Please do let us know . Please include the URL for the opinion, the corrected information and a source where we can verify the correction.

We're only able to make corrections to court opinions that are hosted on our own website. For corrections to academic papers, books, dissertations and other third-party material, click on the search result in question and contact the owner of the website where the document came from. For corrections to books from Google Book Search, click on the book's title and locate the link to provide feedback at the bottom of the book's page.

General Questions

These are articles which other scholarly articles have referred to, but which we haven't found online. To exclude them from your search results, uncheck the "include citations" box on the left sidebar.

First, click on links labeled [PDF] or [HTML] to the right of the search result's title. Also, check out the "All versions" link at the bottom of the search result.

Second, if you're affiliated with a university, using a computer on campus will often let you access your library's online subscriptions. Look for links labeled with your library's name to the right of the search result's title. Also, see if there's a link to the full text on the publisher's page with the abstract.

Keep in mind that final published versions are often only available to subscribers, and that some articles are not available online at all. Good luck!

Technically, your web browser remembers your settings in a "cookie" on your computer's disk, and sends this cookie to our website along with every search. Check that your browser isn't configured to discard our cookies. Also, check if disabling various proxies or overly helpful privacy settings does the trick. Either way, your settings are stored on your computer, not on our servers, so a long hard look at your browser's preferences or internet options should help cure the machine's forgetfulness.

Not even close. That phrase is our acknowledgement that much of scholarly research involves building on what others have already discovered. It's taken from Sir Isaac Newton's famous quote, "If I have seen further, it is by standing on the shoulders of giants."

The Research Process

Planning : Before searching for articles or books, brainstorm to develop keywords that better describe your research question.

Searching : While searching, take note of what other keywords are used to describe your topic, and use them to conduct additional searches

     ♠ Most articles include a keyword section

     ♠ Key concepts may change names throughout time so make sure to check for variations

Organizing : Start organizing your results by categories/key concepts or any organizing principle that make sense for you . This will help you later when you are ready to analyze your findings

Analyzing : While reading, start making notes of key concepts and commonalities and disagreement among the research articles you find.

♠ Create a spreadsheet  to record what articles you are finding useful and why.

♠ Create fields to write summaries of articles or quotes for future citing and paraphrasing .

Writing : Synthesize your findings. Use your own voice to explain to your readers what you learned about the literature on your topic. What are its weaknesses and strengths? What is missing or ignored?

Repeat : At any given time of the process, you can go back to a previous step as necessary.

Advanced Searching

All databases have Help pages that explain the best way to search their product. When doing literature reviews, you will want to take advantage of these features since they can facilitate not only finding the articles that you really need but also controlling the number of results and how relevant they are for your search. The most common features available in the advanced search option of databases and library online catalogs are:

• Boolean Searching (AND, OR, NOT): Allows you to connect search terms in a way that can either limit or expand your search results 
• Proximity Searching (N/# or W/#): Allows you to search for two or more words that occur within a specified number of words (or fewer) of each other in the database
• Limiters/Filters : These are options that let you control what type of document you want to search: article type, date, language, publication, etc.
• Question mark (?) or a pound sign (#) for wildcard: Used for retrieving alternate spellings of a word: colo?r will retrieve both the American spelling "color" as well as the British spelling "colour." 
• Asterisk (*) for truncation: Used for retrieving multiple forms of a word: comput* retrieves computer, computers, computing, etc.

Want to keep track of updates to your searches? Create an account in the database to receive an alert when a new article is published that meets your search parameters!

• Library's General Search Tips Check the Search tips to better used our library catalog and articles search system
• ProQuest Database Search Tips Tips for searching another platform that hosts library databases

There is no magic number regarding how many sources you are going to need for your literature review; it all depends on the topic and what type of the literature review you are doing:

► Are you working on an emerging topic? You are not likely to find many sources, which is good because you are trying to prove that this is a topic that needs more research. But, it is not enough to say that you found few or no articles on your topic in your field. You need to look broadly to other disciplines (also known as triangulation ) to see if your research topic has been studied from other perspectives as a way to validate the uniqueness of your research question.

► Are you working on something that has been studied extensively? Then you are going to find many sources and you will want to limit how far back you want to look. Use limiters to eliminate research that may be dated and opt to search for resources published within the last 5-10 years.

How to find the right journal for your research (using actual data)

Joanna Wilkinson

Want to help your research flourish? We share tips for using publisher-neutral data and statistics to find the right journal for your research paper.

The right journal helps your research flourish. It puts you in the best position to reach a relevant and engaged audience, and can extend the impact of your paper through a high-quality publishing process.

Unfortunately, finding the right journal is a particular pain point for inexperienced authors and those who publish on interdisciplinary topics. The sheer number of journals published today is one reason for this. More than 42,000 active scholarly peer-reviewed journals were published in 2018 alone, and there’s been accelerated growth of more than 5% in recent years.

The overwhelming growth in journals has left many researchers struggling to find the best home for their manuscripts which can be a daunting prospect after several long months producing research. Submitting to the wrong journal can hinder the impact of your manuscript. It could even result in a series of rejections, stalling both your research and career. Conversely, the right journal can help you showcase your research to the world in an environment consistent with your values.

Keep reading to learn how solutions like Journal Citation Reports ™ (JCR) and Master Journal List   can help you find the right journal for your research in the fastest possible time.

What to look for in a journal and why

To find the right journal for your research paper, it’s important to consider what you need and want out of the publishing process.

The goal for many researchers is to find a prestigious, peer-reviewed journal to publish in. This might be one that can support an application for tenure, promotion or future funding. It’s not always that simple, however. If your research is in a specialized field, you may want to avoid a journal with a multidisciplinary focus. And if you have ground-breaking results, you may want to pay attention to journals with a speedy review process and frequent publication schedule. Moreover, you may want to publish your paper as open access so that it’s accessible to everyone—and your institution or funder may also require this.

With so many points to consider, it’s good practice to have a journal in mind before you start writing. We published an earlier post to help you with this: Find top journals in a research field, step-by-step guide . Check it out to discover where the top researchers in your field are publishing.

Already written your manuscript? No problem: this blog will help you use publisher-neutral data and statistics to choose the right journal for your paper.

First stop: Manuscript Matcher in the Master Journal List

Master Journal List Manuscript Matcher is the ultimate place to begin your search for journals. It is a free tool that helps you narrow down your journal options based on your research topic and goals.

Pairing your research with a journal

Manuscript Matcher, also available via EndNote™ , provides a list of relevant journals indexed in the Web of Science™ . First, you’ll want to input your title and abstract (or keywords, if you prefer). You can then filter your results using the options shown on the left-hand sidebar, or simply click on the profile page of any journal listed.

Each journal page details the journal’s coverage in the Web of Science. Where available, it may also display a wealth of information, including:

• open access information (including whether a journal is Gold OA)
• the journal’s aims and scope
• download statistics
• average number of weeks from submission to publication, and
• peer review information (including type and policy)

Ready to try Manuscript Matcher? Follow this link .

Identify the journals that are a good topical fit for your research using Manuscript Matcher. You can then move to Journal Citation Reports to understand their citation impact, audience and open access statistics.

Find the right journal with Journal Citation Reports

Journal Citation Reports   is the most powerful solution for journal intelligence. It uses transparent, publisher-neutral data and statistics to provide unique insight into a journal’s role and influence. This will help you produce a definitive list of journals best-placed to publish your findings, and more.

Three data points exist on every journal page to help you assess a journal as a home for your research. These are: citation metrics, article relevance and audience.

Citation Metrics

The Journal Impact Factor™ (JIF) is included as part of the rich array of citation metrics offered on each journal page. It shows how often a journal’s recently published material is cited on average.

Learn how the JIF is calculated in this guide .

It’s important to note that the JIF has its limitations and no researcher should depend on the impact factor alone when assessing the usefulness or prestige of a journal. Journal Citation Reports helps you understand the context of a journal’s JIF and how to use the metric responsibly.

The JCR Trend Graph, for example, places the JIF in the context of time and subject category performance. Citation behavior varies across disciplines, and journals in JCR may be placed across multiple subject categories depending on the scope of their content. The Trend Graph shows you how the journal performs against others in the same subject category. It also gives you an understanding of how stable that performance is year-on-year.

You can learn more about this here .

The 2021 JCR release introduced a new, field-normalized metric for measuring the citation impact of a journal’s recent publications. By normalizing for different fields of research and their widely varying rates of publication and citation, the Journal Citation Indicator provides a single journal-level metric that can be easily interpreted and compared across disciplines. Learn more about the Journal Citation Indicator here .

Article relevance

The Contributing Items section in JCR demonstrates whether the journal is a good match for your paper. It can also validate the information you found in the Manuscript Matcher. You can view the full list in the Web of Science by selecting “Show all.”

JCR helps you understand the scholarly community engaging with a journal on both a country and an institutional level. This information provides insight on where in the world your own paper might have an impact if published in that particular journal. It also gives you a sense of general readership, and who you might be talking to if you choose that journal.

Start using Journal Citation Reports today .

Ready to find the right journal for your paper?

The expansion of scholarly journals in previous years has made it difficult for researchers to choose the right journal for their research. This isn’t a good position to be in when you’ve spent many long months preparing your research for the world. Journal Citation Reports , Manuscript Matcher by Master Journal List  and the Web of Science  are all products dedicated to helping you find the right home for your paper.

The Ultimate Student Guide To Finding Credible Sources

Updated: January 24, 2023

Published: January 1, 2020

When it comes to writing a research paper, it’s crucial that you use credible sources to make sure that the information you are stating is actually true. Knowing the difference between credible sources and unreliable sources doesn’t always come so easily with endless information flooding the internet. Thankfully, there are some simple tips that you can use to ensure that you are always using credible sources for research.

What is a Research Paper?

A research paper is a piece of academic writing that uses original research on a specific topic. There are many different types of research papers, ranging from a high school term paper to a master’s thesis or doctoral dissertation.

How to start a search for sources, 1. start simple.

If you’re wondering how to find sources for a research paper, the easiest and best way to start is simple! Just try browsing through some common search engines to see what you find.

2. Cross Wikipedia off

Wikipedia, although it’s a massive pool of information, should always be avoided when writing a research paper since it allows the public to edit information. Sites such as these often run the risk of lacking accuracy, and is not one of the most credible sources for research.

3. Yes to scholarly databases

Scholarly databases are your best friend when it comes to finding credible sources for research. Online scholarly databases that can be trusted and are known to provide useful information for students include LexisNexis and EBSCO.

4. Newspapers and magazines

Although sometimes biased, newspapers and magazines can also be a great place to find information about current events.

5. The library

While the library seems to be the most obvious place to find information, somehow it’s often forgotten when it comes to research in the modern age. Don’t forget how useful it can truly be!

Types of Credible Sources for Research

1. what are some credible websites.

Many online sources do not necessarily contain information that is correct or has been checked. That’s why it’s of utmost importance to make sure that you’re using the right websites for your research, with government and educational websites generally being the most reliable.

Credible sources for research include: science.gov, The World Factbook, US Census Bureau, UK Statistics, and Encyclopedia Britannica.

2. What are some credible journal articles?

When it comes to journal articles, determining how credible they are comes much easier than other sources. This is generally due to the fact that many of these websites will include valuable information such as how many times the article has been cited, and if its been peer reviewed.

Some great examples of reliable websites for journal articles include Google Scholar, Oxford Academic, Microsoft Academic, Cornell University Library, and SAGE Publishing.

If you are ever not sure how to find credible sources, then there’s the CRAAP test, which takes into account the Currency, Relevance, Authority, Accuracy and Purpose of the article. Take all of these factors into consideration before using a source and determining whether or not it’s credible enough. Even if it takes more time, you’ll be saving yourself tons of time in the long run by not using unreliable sources.

3. what are some credible news sources.

When it comes to news articles, more caution must be taken since it’s hard to know which sources are truly reliable and unbiased. The CRAAP test is also useful in this type of article for research.

A few examples of credible news sources include The New York Times, Bloomberg, and The Washington Post.

The Credibility of a Source

As you search for your research information, you will surely come across the question of how to find credible sources for a research paper. Here are some criteria to focus on to ensure that you only use the most credible of sources.

1. What’s the depth of it?

Always look at the depth of an article, not just the written content. See how long the article is, and if it contains the necessary information such as an abstract, a reference list, and documented data.

2. Who is reading it?

When judging the credibility of an article, it’s important to always ask yourself who the target audience of the article is. Sometimes, sources have a specific goal in mind and it can create certain biases.

3. What’s the goal?

Just as you should do with the audience, also ask yourself what the article is trying to achieve. What is their ultimate goal and how are they persuading you of that?

4. Who wrote it?

Always ask yourself who wrote the article and how reputable they are in the specific field. Look at what other published works they have as well.

5. Can it be trusted?

Overall, it’s key to ask yourself how reputable the source is. What kind of website is it published on? Look at the big picture.

6. Is it relevant to now?

Look at the date of the article, or about the specific things they are mentioning in the article. If it’s from a few years ago, it’s probably not too relevant to your current research.

7. Can it be proven?

While an article may sound incredibly convincing, many people have a way with words and persuasion. Stop and ask yourself whether or not what they are claiming can actually be proven.

How to evaluate source credibility.

By using unreliable sources in your research, it can discredit your status, which is why it’s incredibly important to make sure that any information you are using is up-to-date and accurate.

Here’s how to find credible sources.

1. What is a credible source?

Generally, materials that have been published within the past 10 years are considered to be credible sources for research. Another important factor to consider is the author — if they are well known and respected in their specific fields, that’s also generally a sign that the article is credible. Educational and government-run websites (.gov, .edu) tend to also be a safe source to use, as well as academic databases. Google Scholar is also a no-fail source for reliable information.

2. What is a potentially unreliable source?

Anything that is out of date, meaning it’s been published more than 10 years ago should be avoided. Materials published on social media platforms such as Facebook or personal blogs don’t tend to be the most credible. Always make sure that an article contains proper citations and that the website you are using ends in .com or .org.

Free Resources For Learning

There are many free resources for research available known as open educational resources . They are licensed for free use, with the intention of teaching. They can be determined as credible sources for research if they have a Creative Common license, and if the author has proven to be an expert in their field. Always make sure that the content you are using contains no biases.

Sites For Scholarly Research

When performing scholarly research, it’s extra important to make sure that your sources are credible. Government-run research is considered credible, but beware of any political sites. University and educational websites also tend to be reliable, but still take everything you read with a grain of salt. Company websites also tend to be reliable, although their ultimate goal is usually to promote a product. Organizations which are .org websites can be professional and reliable, however, sometimes they also have their own interests.

Which Sites Can Be Relied On

The internet has no shortage of information out there. That’s why you’ll need these handy tips to determine which to use, and how to distinguish through the vast choices without feeling overwhelmed.

List of Credible Research Sources to Consider

1. government entities.

These websites tend to be reliable since they are highly regulated. Examples include the CIA World Factbook and the United States Justice Statistics.

2. Research Think Tanks

Examples of reliable research think tanks include Rand Corporation, Pew Research Center and The Milken Institute.

3. Academic Libraries and Databases

ProQuest, Scopus, and Jstor are great examples of academic libraries and databases that can be trusted.

4. Professional Standards Organizations

The American Bar Association and The American Psychological Association (APA) are highly credible sources when it comes to professional standards.

How to Write a Research Paper: Step-by-Step

Now that you’re an expert on finding credible sources for research, you’re ready to go! But how do you even start to write a research paper? Don’t worry, we’ve got you covered.

For starters, it’s important to get clear instructions from your professor on what they want. The next step is to start brainstorming ideas for a topic of research. Once you’ve decided and feel confident about it, you’re ready to create your outline and plan out the goal of your research paper.

Befriend your librarian and start to search for quality and credible sources through a variety of means. Make sure you understand your topic from top to bottom before you start writing.  As you write, be sure to always keep things factual, and that you finalize your thesis statement throughout your paper — not just at the end. That’s what’s going to guide your writing. Be sure to always keep format in mind, never forget to cite your sources, and to never skip those edits and final checks.

Now you are ready to write a high-quality, fact-driven research paper that’s sure to impress your professors.

Sat / act prep online guides and tips, 113 great research paper topics.

General Education

One of the hardest parts of writing a research paper can be just finding a good topic to write about. Fortunately we've done the hard work for you and have compiled a list of 113 interesting research paper topics. They've been organized into ten categories and cover a wide range of subjects so you can easily find the best topic for you.

In addition to the list of good research topics, we've included advice on what makes a good research paper topic and how you can use your topic to start writing a great paper.

What Makes a Good Research Paper Topic?

Not all research paper topics are created equal, and you want to make sure you choose a great topic before you start writing. Below are the three most important factors to consider to make sure you choose the best research paper topics.

#1: It's Something You're Interested In

A paper is always easier to write if you're interested in the topic, and you'll be more motivated to do in-depth research and write a paper that really covers the entire subject. Even if a certain research paper topic is getting a lot of buzz right now or other people seem interested in writing about it, don't feel tempted to make it your topic unless you genuinely have some sort of interest in it as well.

#2: There's Enough Information to Write a Paper

Even if you come up with the absolute best research paper topic and you're so excited to write about it, you won't be able to produce a good paper if there isn't enough research about the topic. This can happen for very specific or specialized topics, as well as topics that are too new to have enough research done on them at the moment. Easy research paper topics will always be topics with enough information to write a full-length paper.

Trying to write a research paper on a topic that doesn't have much research on it is incredibly hard, so before you decide on a topic, do a bit of preliminary searching and make sure you'll have all the information you need to write your paper.

#3: It Fits Your Teacher's Guidelines

Don't get so carried away looking at lists of research paper topics that you forget any requirements or restrictions your teacher may have put on research topic ideas. If you're writing a research paper on a health-related topic, deciding to write about the impact of rap on the music scene probably won't be allowed, but there may be some sort of leeway. For example, if you're really interested in current events but your teacher wants you to write a research paper on a history topic, you may be able to choose a topic that fits both categories, like exploring the relationship between the US and North Korea. No matter what, always get your research paper topic approved by your teacher first before you begin writing.

How to Write a Great Research Paper

Even great research paper topics won't give you a great research paper if you don't hone your topic before and during the writing process. Follow these three tips to turn good research paper topics into great papers.

#1: Figure Out Your Thesis Early

Before you start writing a single word of your paper, you first need to know what your thesis will be. Your thesis is a statement that explains what you intend to prove/show in your paper. Every sentence in your research paper will relate back to your thesis, so you don't want to start writing without it!

As some examples, if you're writing a research paper on if students learn better in same-sex classrooms, your thesis might be "Research has shown that elementary-age students in same-sex classrooms score higher on standardized tests and report feeling more comfortable in the classroom."

If you're writing a paper on the causes of the Civil War, your thesis might be "While the dispute between the North and South over slavery is the most well-known cause of the Civil War, other key causes include differences in the economies of the North and South, states' rights, and territorial expansion."

#2: Back Every Statement Up With Research

Remember, this is a research paper you're writing, so you'll need to use lots of research to make your points. Every statement you give must be backed up with research, properly cited the way your teacher requested. You're allowed to include opinions of your own, but they must also be supported by the research you give.

#3: Do Your Research Before You Begin Writing

You don't want to start writing your research paper and then learn that there isn't enough research to back up the points you're making, or, even worse, that the research contradicts the points you're trying to make!

Get most of your research on your good research topics done before you begin writing. Then use the research you've collected to create a rough outline of what your paper will cover and the key points you're going to make. This will help keep your paper clear and organized, and it'll ensure you have enough research to produce a strong paper.

How can I plan what to eat or drink when I have diabetes?

How can physical activity help manage my diabetes, what can i do to reach or maintain a healthy weight, should i quit smoking, how can i take care of my mental health, clinical trials for healthy living with diabetes.

Healthy living is a way to manage diabetes . To have a healthy lifestyle, take steps now to plan healthy meals and snacks, do physical activities, get enough sleep, and quit smoking or using tobacco products.

Healthy living may help keep your body’s blood pressure , cholesterol , and blood glucose level, also called blood sugar level, in the range your primary health care professional recommends. Your primary health care professional may be a doctor, a physician assistant, or a nurse practitioner. Healthy living may also help prevent or delay health problems  from diabetes that can affect your heart, kidneys, eyes, brain, and other parts of your body.

Making lifestyle changes can be hard, but starting with small changes and building from there may benefit your health. You may want to get help from family, loved ones, friends, and other trusted people in your community. You can also get information from your health care professionals.

What you choose to eat, how much you eat, and when you eat are parts of a meal plan. Having healthy foods and drinks can help keep your blood glucose, blood pressure, and cholesterol levels in the ranges your health care professional recommends. If you have overweight or obesity, a healthy meal plan—along with regular physical activity, getting enough sleep, and other healthy behaviors—may help you reach and maintain a healthy weight. In some cases, health care professionals may also recommend diabetes medicines that may help you lose weight, or weight-loss surgery, also called metabolic and bariatric surgery.

Choose healthy foods and drinks

There is no right or wrong way to choose healthy foods and drinks that may help manage your diabetes. Healthy meal plans for people who have diabetes may include

• dairy or plant-based dairy products
• nonstarchy vegetables
• protein foods
• whole grains

Try to choose foods that include nutrients such as vitamins, calcium , fiber , and healthy fats . Also try to choose drinks with little or no added sugar , such as tap or bottled water, low-fat or non-fat milk, and unsweetened tea, coffee, or sparkling water.

Try to plan meals and snacks that have fewer

• foods high in saturated fat
• foods high in sodium, a mineral found in salt
• sugary foods , such as cookies and cakes, and sweet drinks, such as soda, juice, flavored coffee, and sports drinks

Your body turns carbohydrates , or carbs, from food into glucose, which can raise your blood glucose level. Some fruits, beans, and starchy vegetables—such as potatoes and corn—have more carbs than other foods. Keep carbs in mind when planning your meals.

You should also limit how much alcohol you drink. If you take insulin  or certain diabetes medicines , drinking alcohol can make your blood glucose level drop too low, which is called hypoglycemia . If you do drink alcohol, be sure to eat food when you drink and remember to check your blood glucose level after drinking. Talk with your health care team about your alcohol-drinking habits.

Find the best times to eat or drink

Talk with your health care professional or health care team about when you should eat or drink. The best time to have meals and snacks may depend on

• what medicines you take for diabetes
• what your level of physical activity or your work schedule is
• whether you have other health conditions or diseases

Ask your health care team if you should eat before, during, or after physical activity. Some diabetes medicines, such as sulfonylureas  or insulin, may make your blood glucose level drop too low during exercise or if you skip or delay a meal.

Plan how much to eat or drink

You may worry that having diabetes means giving up foods and drinks you enjoy. The good news is you can still have your favorite foods and drinks, but you might need to have them in smaller portions  or enjoy them less often.

For people who have diabetes, carb counting and the plate method are two common ways to plan how much to eat or drink. Talk with your health care professional or health care team to find a method that works for you.

Carb counting

Carbohydrate counting , or carb counting, means planning and keeping track of the amount of carbs you eat and drink in each meal or snack. Not all people with diabetes need to count carbs. However, if you take insulin, counting carbs can help you know how much insulin to take.

Plate method

The plate method helps you control portion sizes  without counting and measuring. This method divides a 9-inch plate into the following three sections to help you choose the types and amounts of foods to eat for each meal.

• Nonstarchy vegetables—such as leafy greens, peppers, carrots, or green beans—should make up half of your plate.
• Carb foods that are high in fiber—such as brown rice, whole grains, beans, or fruits—should make up one-quarter of your plate.
• Protein foods—such as lean meats, fish, dairy, or tofu or other soy products—should make up one quarter of your plate.

If you are not taking insulin, you may not need to count carbs when using the plate method.

Work with your health care team to create a meal plan that works for you. You may want to have a diabetes educator  or a registered dietitian  on your team. A registered dietitian can provide medical nutrition therapy , which includes counseling to help you create and follow a meal plan. Your health care team may be able to recommend other resources, such as a healthy lifestyle coach, to help you with making changes. Ask your health care team or your insurance company if your benefits include medical nutrition therapy or other diabetes care resources.

Talk with your health care professional before taking dietary supplements

There is no clear proof that specific foods, herbs, spices, or dietary supplements —such as vitamins or minerals—can help manage diabetes. Your health care professional may ask you to take vitamins or minerals if you can’t get enough from foods. Talk with your health care professional before you take any supplements, because some may cause side effects or affect how well your diabetes medicines work.

Research shows that regular physical activity helps people manage their diabetes and stay healthy. Benefits of physical activity may include

• lower blood glucose, blood pressure, and cholesterol levels
• better heart health
• healthier weight
• better mood and sleep
• better balance and memory

Talk with your health care professional before starting a new physical activity or changing how much physical activity you do. They may suggest types of activities based on your ability, schedule, meal plan, interests, and diabetes medicines. Your health care professional may also tell you the best times of day to be active or what to do if your blood glucose level goes out of the range recommended for you.

Do different types of physical activity

People with diabetes can be active, even if they take insulin or use technology such as insulin pumps .

Try to do different kinds of activities . While being more active may have more health benefits, any physical activity is better than none. Start slowly with activities you enjoy. You may be able to change your level of effort and try other activities over time. Having a friend or family member join you may help you stick to your routine.

The physical activities you do may need to be different if you are age 65 or older , are pregnant , or have a disability or health condition . Physical activities may also need to be different for children and teens . Ask your health care professional or health care team about activities that are safe for you.

Aerobic activities

Aerobic activities make you breathe harder and make your heart beat faster. You can try walking, dancing, wheelchair rolling, or swimming. Most adults should try to get at least 150 minutes of moderate-intensity physical activity each week. Aim to do 30 minutes a day on most days of the week. You don’t have to do all 30 minutes at one time. You can break up physical activity into small amounts during your day and still get the benefit. 1

Strength training or resistance training

Strength training or resistance training may make your muscles and bones stronger. You can try lifting weights or doing other exercises such as wall pushups or arm raises. Try to do this kind of training two times a week. 1

Balance and stretching activities

Balance and stretching activities may help you move better and have stronger muscles and bones. You may want to try standing on one leg or stretching your legs when sitting on the floor. Try to do these kinds of activities two or three times a week. 1

Some activities that need balance may be unsafe for people with nerve damage or vision problems caused by diabetes. Ask your health care professional or health care team about activities that are safe for you.

Stay safe during physical activity

Staying safe during physical activity is important. Here are some tips to keep in mind.

Drink liquids

Drinking liquids helps prevent dehydration , or the loss of too much water in your body. Drinking water is a way to stay hydrated. Sports drinks often have a lot of sugar and calories , and you don’t need them for most moderate physical activities.

Avoid low blood glucose

Check your blood glucose level before, during, and right after physical activity. Physical activity often lowers the level of glucose in your blood. Low blood glucose levels may last for hours or days after physical activity. You are most likely to have low blood glucose if you take insulin or some other diabetes medicines, such as sulfonylureas.

Ask your health care professional if you should take less insulin or eat carbs before, during, or after physical activity. Low blood glucose can be a serious medical emergency that must be treated right away. Take steps to protect yourself. You can learn how to treat low blood glucose , let other people know what to do if you need help, and use a medical alert bracelet.

Avoid high blood glucose and ketoacidosis

Taking less insulin before physical activity may help prevent low blood glucose, but it may also make you more likely to have high blood glucose. If your body does not have enough insulin, it can’t use glucose as a source of energy and will use fat instead. When your body uses fat for energy, your body makes chemicals called ketones .

High levels of ketones in your blood can lead to a condition called diabetic ketoacidosis (DKA) . DKA is a medical emergency that should be treated right away. DKA is most common in people with type 1 diabetes . Occasionally, DKA may affect people with type 2 diabetes  who have lost their ability to produce insulin. Ask your health care professional how much insulin you should take before physical activity, whether you need to test your urine for ketones, and what level of ketones is dangerous for you.

Take care of your feet

People with diabetes may have problems with their feet because high blood glucose levels can damage blood vessels and nerves. To help prevent foot problems, wear comfortable and supportive shoes and take care of your feet  before, during, and after physical activity.

If you have diabetes, managing your weight  may bring you several health benefits. Ask your health care professional or health care team if you are at a healthy weight  or if you should try to lose weight.

If you are an adult with overweight or obesity, work with your health care team to create a weight-loss plan. Losing 5% to 7% of your current weight may help you prevent or improve some health problems  and manage your blood glucose, cholesterol, and blood pressure levels. 2 If you are worried about your child’s weight  and they have diabetes, talk with their health care professional before your child starts a new weight-loss plan.

You may be able to reach and maintain a healthy weight by

• following a healthy meal plan
• consuming fewer calories
• being physically active
• getting 7 to 8 hours of sleep each night 3

If you have type 2 diabetes, your health care professional may recommend diabetes medicines that may help you lose weight.

Online tools such as the Body Weight Planner  may help you create eating and physical activity plans. You may want to talk with your health care professional about other options for managing your weight, including joining a weight-loss program  that can provide helpful information, support, and behavioral or lifestyle counseling. These options may have a cost, so make sure to check the details of the programs.

Your health care professional may recommend weight-loss surgery  if you aren’t able to reach a healthy weight with meal planning, physical activity, and taking diabetes medicines that help with weight loss.

If you are pregnant , trying to lose weight may not be healthy. However, you should ask your health care professional whether it makes sense to monitor or limit your weight gain during pregnancy.

Both diabetes and smoking —including using tobacco products and e-cigarettes—cause your blood vessels to narrow. Both diabetes and smoking increase your risk of having a heart attack or stroke , nerve damage , kidney disease , eye disease , or amputation . Secondhand smoke can also affect the health of your family or others who live with you.

If you smoke or use other tobacco products, stop. Ask for help . You don’t have to do it alone.

Feeling stressed, sad, or angry can be common for people with diabetes. Managing diabetes or learning to cope with new information about your health can be hard. People with chronic illnesses such as diabetes may develop anxiety or other mental health conditions .

Learn healthy ways to lower your stress , and ask for help from your health care team or a mental health professional. While it may be uncomfortable to talk about your feelings, finding a health care professional whom you trust and want to talk with may help you

• lower your feelings of stress, depression, or anxiety
• manage problems sleeping or remembering things
• see how diabetes affects your family, school, work, or financial situation

Ask your health care team for mental health resources for people with diabetes.

Sleeping too much or too little may raise your blood glucose levels. Your sleep habits may also affect your mental health and vice versa. People with diabetes and overweight or obesity can also have other health conditions that affect sleep, such as sleep apnea , which can raise your blood pressure and risk of heart disease.

NIDDK conducts and supports clinical trials in many diseases and conditions, including diabetes. The trials look to find new ways to prevent, detect, or treat disease and improve quality of life.

What are clinical trials for healthy living with diabetes?

Clinical trials—and other types of clinical studies —are part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help health care professionals and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of healthy living for people with diabetes, such as

• how changing when you eat may affect body weight and metabolism
• how less access to healthy foods may affect diabetes management, other health problems, and risk of dying
• whether low-carbohydrate meal plans can help lower blood glucose levels
• which diabetes medicines are more likely to help people lose weight

8 Good Reasons to Own Gold

Michael Bromberg is a finance editor with a decade of experience. He is an expert at elucidating complex financial topics in clear, concise language. Michael received a Bachelor of Arts in literature from the University of Wisconsin-Madison and a master's in linguistics from the Universidad de Antioquia in Medellin, Colombia.

Gold is respected around the world for its value and rich history, which has been recognized by cultures for thousands of years. Coins containing gold appeared around 550 B.C., during the reign of King Croesus of Lydia.

Throughout the centuries, people have continued to hold gold for various reasons. Societies, and now economies, have placed value on gold, thus perpetuating its worth. It is the metal we fall back on when other forms of currency don’t work, which means it always has some value as insurance against tough times.

Below are eight practical reasons to think about owning some gold.

Key Takeaways

• Throughout history, gold has been seen as a special and valuable commodity.
• Today, owning gold can act as a hedge against inflation and deflation alike, as well as a good portfolio diversifier.
• As a global store of value, gold can also provide financial cover during geopolitical and macroeconomic uncertainty.

Unlike paper currency, coins, or other assets, gold has maintained its value throughout the ages. People see gold as a way to pass on and preserve their wealth from one generation to the next. Since ancient times, people have valued the unique properties of the precious metal .

Gold doesn’t corrode and can be melted over a common flame, making it easy to work with and stamp as a coin. Moreover, gold has a unique and beautiful color, unlike other elements. The atoms in gold are heavier, and the electrons move faster, creating absorption of some light—a process that took Einstein’s theory of relativity to figure out.

Although the U.S. dollar is one of the world's most important reserve currencies, when the value of the dollar falls against other currencies—as it did from 1998 to 2008—this often prompts people to flock to the security of gold, which raises gold prices. The price of gold nearly tripled from 1998 to 2008, reaching the $1,000-an-ounce milestone in early 2008 and nearly doubling from 2008 to 2012, rising above the $2,000 mark. The decline in the U.S. dollar then occurred for a number of reasons, including the country’s large budget and trade deficits and a large increase in the money supply.

Gold has historically been an excellent hedge against inflation because its price tends to rise when the cost of living increases. Over the past 50 years, investors have seen gold prices soar and the stock market plunge during high-inflation years. This is because when fiat currency loses its purchasing power to inflation, gold tends to be priced in those currency units and thus tends to rise along with everything else. Moreover, gold is seen as a good store of value, so people may be encouraged to buy gold when they believe that their local currency is losing value.

Although inflation soared in 2022, gold prices actually declined for most of the year, driven in part by the strength of the U.S. dollar against other currencies. However, with inflation remaining at persistently high levels alongside concerns about a potential recession , gold prices ticked higher in the final months of 2022 and early in 2023.

Deflation is defined as a period when prices decrease, business activity slows, and the economy is burdened by excessive debt. This has not been seen globally since the Great Depression of the 1930s (although a small degree of deflation occurred following the 2008 financial crisis in some parts of the world). During the Depression, the relative purchasing power of gold soared while other prices dropped sharply. This is because people chose to hoard cash, and the safest place to hold cash at the time was in gold and gold coins.

Gold retains its value not only in times of financial uncertainty but also in times of geopolitical uncertainty. It is often called the “crisis commodity” because people flee to its relative safety when world tensions rise. During such times, gold often outperforms other investments. Its price often rises the most when confidence in governments is low .

Much of the supply of gold in the market since the 1990s has come from sales of gold bullion from the vaults of global central banks . This selling by global central banks slowed greatly in 2008. At the same time, the production of new gold from mines has been declining since 2000.

According to BullionVault, annual gold-mining output fell to 2,444 metric tons in 2007 from 2,573 metric tons in 2000. Since then, gold production has posted a decade of gains, peaking at 3,300 metric tons in 2018 and 2019 before peaking again to 3,644 metric tons in 2023.

In previous years, increased wealth of emerging market economies boosted demand for gold. In many of these countries, gold is an integral part of the culture. In China, where gold bars are a traditional form of saving, the demand for gold has remained steadfast. India is the second-largest gold-consuming nation in the world; it has many uses there, including jewelry. As such, the Indian wedding season in October is traditionally the time of the year that fuels the highest global demand for gold.

Demand for gold also has grown among investors. Many are beginning to see commodities, particularly gold, as an investment class into which funds should be allocated. In fact, the SPDR Gold Trust ( GLD ) has become one of the largest and most frequently traded exchange-traded funds (ETFs) in the United States.

The key to diversification is finding investments that are not closely correlated with one another. Gold has historically had a negative correlation to stocks and other financial instruments. Recent history bears this out:

• The late 1970s were great for gold but terrible for stocks.
• The 1970s and 1980s were great for gold but terrible for stocks.
• The late 1990s and mid-2000s were excellent for stocks but horrible for gold.

Properly diversified investors combine gold with stocks and bonds in a portfolio to reduce the overall volatility and risk.

Why Should I Invest in Gold?

There are many reasons to consider adding gold holdings to your investment portfolio. The precious metal has a history of maintaining its value, making gold a useful hedge against inflation. Gold prices tend to increase when the U.S. dollar is underperforming or during times of economic and political uncertainty. Finally, gold can provide an important level of diversification to your portfolio, as gold prices have historically shown a negative correlation with other asset classes.

What Determines the Price of Gold?

Gold prices can be volatile in the short term, but the metal has maintained its value over the long term. In general, movements in the price of gold depend on supply, demand, and investor behavior. Because the metal is often used to hedge against inflation, the pace of inflation—and market expectations for future inflation levels—can have an impact on gold prices. In addition, deteriorating economic conditions may bolster gold prices because the metal is seen as a relatively safe investment in difficult times.

How Can I Invest in Gold?

There are many vehicles for adding investment exposure to gold. It is possible to own the physical metal in forms such as bullion, coins, or jewelry, although storing and insuring physical gold assets can be costly. Other possibilities include investing in a gold exchange-traded fund (ETF) or buying shares in mining companies that engage in the extraction and production of the precious metal.

Gold should be an important part of a diversified investment portfolio because its price increases in response to events that cause the value of paper investments, such as stocks and bonds, to decline. Although the price of gold can be volatile in the short term, it always has maintained its value over the long term. Through the years, gold has served as a hedge against inflation and the erosion of major currencies, and thus is an investment well worth considering.

• 10 great health foods

The food you eat every day can make a difference in your health. Diet affects your risk of getting some cancers, heart disease or type 2 diabetes. Diet also affects the risk of low bone density and loss of muscle strength with aging.

But a healthy diet can include a huge range of foods. How do you choose?

Some of the best foods for health combine nutrients, such as vitamins, minerals, fats and protein. If those foods also have limited amounts of added sugar, fat or salt added to them, they are called nutrient-dense foods.

Foods that are a source of fiber, vitamins and minerals and that are high in plant chemicals called phytonutrients are a bonus. Eating nutrient-dense foods regularly, over time, is linked to a lower risk of some chronic diseases.

Here are 10 great foods to add or increase in your diet.

Nuts eaten whole are considered a protein, in the same category as seeds, meats and eggs. They may also be processed into an oil. But nuts have more than protein and fat going for them. They're filled with vitamins, minerals, fiber and antioxidants.

Almonds are a good example. They are tree nuts and can be used whole or ground into butter and everything in between. Almonds add crunch to snack time, salads and dishes that range from appetizers to desserts.

Almonds are a source of magnesium, calcium and folate. Just 1 ounce of almonds meets a large amount of the daily need for vitamin E. And most of the fat in almonds is in the form of monounsaturated fatty acids. This type of fat, when it replaces saturated fat, is linked to heart health.

Nuts are a strong addition to a healthy diet. But they can pack a big calorie punch. So watch portion size and make sure the nuts you choose fit into your daily calorie plan. Choose unsalted whole nuts or nut butter without added salt or sugar.

Most people could use more fruit in their daily diet, according to surveys. Apples are a handy and reliable way to check that box every day.

Different apple varieties can satisfy tastebuds that lean toward tart or sweet. And apples are a good source of fiber. Apple skins have fiber that doesn't break down in water, called insoluble fiber. The inside part of the apple has soluble fiber, which becomes a sort of gel as it travels through the intestines.

Soluble and insoluble fiber helps keep food moving in the digestive system and may lower the risk of getting some cancers. Soluble fiber also may lower the risk of cardiovascular disease.

Like other plant foods, apples have phytonutrients. These are things like vitamin C, and in apples, flavonoids, as well as many others. Together these chemicals seem to support the body's cells against damage from day-to-day living.

As both a vegetable and a source of protein, beans are a good addition to every meal. Each type of bean has its own profile of nutrients, but all beans are low-fat sources of protein and fiber. Beans also bring thiamin, magnesium, iron, zinc, folate, phosphorus and potassium to the diet.

With so many options, it's hard to find a meal where beans can't play a starring role.

But American diets are often low in average intake of beans, peas and lentils. To boost your intake, consider replacing higher fat proteins with beans. And if you're looking at canned beans, go for low sodium.

Blueberries

Another great fruit to add to the daily diet are blueberries. Alone, in yogurt, or added to salad, blueberries are packed with phytonutrients. One example are anthocyanins, which give blueberries their color and are linked to memory health, among other benefits.

Blueberries also have vitamin K. This vitamin supports the body’s cells, healthy blood flow and calcium processing. Vitamin K works together with manganese, which also is found in blueberries.

And blueberries are a low-calorie source of fiber and vitamin C. About 3/4 cup of fresh blueberries has 2.7 grams of fiber and 10.8 milligrams of vitamin C.

Fresh or frozen, blueberries can add color to your plate.

But a note of caution: When it comes to blueberry treats, such as muffins or bagels, the calories may cost you more than you gain, so read the nutrition information.

Broccoli is called a cruciferous vegetable. That means it is in the cabbage family and has phytonutrients linked to immune health and detoxification.

One example is a phytonutrient that contains sulfur, called glucosinolates. Another is lutein, a compound similar to vitamin A that is linked to eye health. And broccoli also is a source of vitamin A, which supports healthy vision.

Broccoli boosts the nutrition of meals with grains, beans or eggs. That's because broccoli's vitamin C helps the body absorb more iron from those foods than it would otherwise. Broccoli also is a source of calcium.

In the fridge, broccoli stays fresh longer than many other vegetables. Roasted, shredded in slaws, or added to vegetable soup, broccoli is a bold flavor that can be enjoyed raw or cooked.

Seafood in general, and salmon in particular, is a good choice for protein in the diet. If you can use salmon in place of a higher fat meat, that's even better.

Salmon is probably best known for its omega-3 fatty acids. Called EPA and DHA, these fats may support heart health, brain function and healthy joints.

Most Americans could add more seafood to their diets, and salmon is a good choice. Salmon can be used fresh or canned. If you buy canned salmon, get it packed in spring water instead of oil.

Salmon can be used in place of tuna in mixed dishes, such as a casserole. Or salmon can be the main protein, as in a salmon burger or taco. Salmon, along with sardines and trout, tend to be lower in mercury than other types of seafood.

Spinach is a leafy green vegetable sold as a bunch. Frozen or fresh, spinach can be part of many dishes, such as those that include eggs, stews or pasta. But fresh, it is a great addition to salads or can stand alone on the dinner plate.

Spinach has vitamins A and C, potassium, carotenoids and folate. Some of the carotenoids found in spinach are beta carotene, lutein and zeaxanthin. These phytonutrients support healthy vision, and proper functioning of the body's cells. Spinach also is a source of iron.

Add spinach to salads, use it in place of lettuce on a sandwich or gently steam it.

Sweet potatoes

Baked or mashed, sweet potatoes are a dish that brightens up any plate. Sweet potatoes have a deep orange-yellow color. That color tells you sweet potatoes are high in the antioxidants known as carotenoids. One of the most studied is beta carotene. It's a substance the body can use to make vitamin A, and it helps cells manage day-to-day wear and tear.

Sweet potatoes are a source of potassium and vitamin A. These veggies also are a source of some B vitamins. And like many vegetables, they are a good source of fiber and relatively low in calories. One-half of a large sweet potato has just 81 calories.

Keep sweet potatoes out of the fridge but in a cool area that is dry and has good airflow.

Vegetable juice

Tomatoes, cucumbers, spinach, beets and carrots are some examples of vegetables that may be juiced. The juice of vegetables often has most of the vitamins, minerals and phytonutrients found in the original vegetable, depending on processing.

The juice will not have the beneficial fiber found in those vegetables. You could add some pulp back to your juice, or just use juicing as a diet boost. If you're buying vegetable juice, look for 100% juice from whole vegetables. And check the amount of salt, which is called sodium on the Nutrition Facts label.

But the good news is that vegetable juice is often a low-calorie, low-sugar, convenient way to add nutrients to your diet.

Whole grains are foods like oats, popcorn and brown rice, where all the edible parts of the grain are still present.

These parts are the bran, the endosperm and the germ. Each part would help a new plant grow if the grain was planted. The germ is where a new plant would sprout from and it has vitamins, minerals, antioxidants and some fats.

Wheat germ is an excellent source of thiamin, and a good source of folate, magnesium, phosphorus and zinc.

Wheat germ can boost the overall nutritional value of a meal. For example, some people sprinkle wheat germ on fruit or in hot cereals such as oatmeal or cold breakfast cereal.

10 foods to get you started

These are just a few of the many options that could make up a nutritious diet. Your best diet depends on your age, activity level, budget, body weight and cultural traditions.

The most important thing to remember is that every bite counts. Focus on eating nutrient-dense foods and avoiding added sugar, sodium and saturated fats to lower your risk of chronic illness over time.

Explore a map of the next 15 total solar eclipses.

In case you miss this year’s solar eclipse, there are 14 more in the next 20 years

This map of eclipse paths from 2024 to 2044 reveals that Australia hit the jackpot: Over just 11 years, the continent (lower right) will see four total solar eclipses — in 2028, 2030, 2037 and 2038.

By Christopher Crockett

April 4, 2024 at 12:00 pm

It’s never too soon to start thinking about the next solar eclipse.

On April 8, the moon’s shadow will sweep across North America , bringing a total solar eclipse over the homes of more than 30 million people ( SN: 1/4/24 ). But even as the shadow departs the continent in eastern Canada, the stage will be getting set for the next total eclipse. And the one after that. And the one after that.

That’s because there’s an order underpinning the mechanics that lead to any eclipse. The breathtaking celestial event is driven by the relentless, repeating rhythms of the Earth’s and moon’s motions. And that means that eclipses of all kinds — not just total solar ones — are predictable across millennia.

Thanks to that predictability, it’s possible to precisely map upcoming solar eclipses. To make this interactive map, Science News relied on NASA’s “Five millennium canon of solar eclipses”  database, a detailed accounting of every solar eclipse from 2000 B.C. to A.D. 3000.

That time span encompasses nearly 12,000 solar eclipses, roughly 3,200 of which are total eclipses. Showing them all would be a bit much. Instead, we show the tracks of the next 15 total solar eclipses, from 2024 to 2044.

In the map, the path for nearly every eclipse (differentiated by color) is marked with three lines: the northern- and southernmost edges of the band in which people will see a total eclipse and the centerline of that band. Along that line, totality lasts longer than near the edges. People in a wide swath to either side of each outer band will be able to see a partial eclipse.

Clicking on a path will offer up some details about that eclipse: The date, the time (in Universal Time ) at which the sun will be eclipsed the longest, the duration of that maximum extent and the width of the eclipse path. And typing a city, landmark or address into the map’s search bar will zoom to that spot, so you can see if any eclipses are due to visit any of your favorite haunts.

And for this year’s eclipse, clicking on any of the white flags along the path will reveal the exact time (also in Universal Time) and duration of totality at that spot.

There is one eclipse here that is a bit unusual. That one will pass through eastern Siberia on April 9, 2043 . On the map, only one line appears — the southernmost limit of totality — because the centerline doesn’t intersect with Earth’s surface. In this “noncentral eclipse,” the centerline and the whole northern half of the shadow will miss Earth entirely, cast off into the depths of space.

Hardcore eclipse fans, intent on seeing every kind imaginable, might want to plan for that one. The next noncentral total eclipse won’t happen until 2459 .
