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 2024.

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.

Determining the Credibility of Scholarly Sources

Ensuring that sources are both credible and reliable is crucial to academic research. Use these strategies to help evaluate the usefulness of scholarly sources:

• Peer Review : Look for articles that have undergone a rigorous peer-review process. Peer-reviewed articles are typically vetted by experts in the field, ensuring the accuracy of the research findings.

Tip: To determine whether an article has undergone rigorous peer review, review the journal's editorial policies, which are often available on the journal's website. Look for information about the peer-review process, including the criteria for selecting reviewers, the process for handling conflicts of interest, and any transparency measures in place.

• Publisher Reputation : Consider the reputation of the publisher. Established publishers, such as well-known academic journals, are more likely to adhere to high editorial standards and publishing ethics.
• Author Credentials : Evaluate the credentials and expertise of the authors. Check their affiliations, academic credentials, and past publications to assess their authority in the field.
• Citations and References : Examine the citations and references provided in the article. A well-researched article will cite credible sources to support its arguments and findings. Verify the accuracy of the cited sources and ensure they are from reputable sources.
• Publication Date : Consider the publication date of the article. While older articles may still be relevant, particularly in certain fields, it is best to prioritize recent publications for up-to-date research and findings.
• Journal Impact Factor : Assess the journal's impact factor or other metrics that indicate its influence and reputation within the academic community. Higher impact factor journals are generally considered more prestigious and reliable. 

Tip: Journal Citation Reports (JCR), produced by Clarivate Analytics, is a widely used source for impact factor data. You can access JCR through academic libraries or directly from the Clarivate Analytics website if you have a subscription.

• Peer Recommendations : Seek recommendations from peers, mentors, or professors in your field. They can provide valuable insights and guidance on reputable sources and journals within your area of study.
• Cross-Verification : Cross-verify the information presented in the article with other credible sources. Compare findings, methodologies, and conclusions with similar studies to ensure consistency and reliability.

By employing these strategies, researchers can confidently evaluate the credibility and reliability of scholarly sources, ensuring the integrity of their research contributions in an ever-evolving landscape.

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, 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 now you have a list of 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.

5 free and legal ways to get the full text of research articles

By Carol Hollier on 07-Apr-2021 13:23:17

1.  Use your library if you have one !

If you are affiliated with a university, you probably have free library access to the full text of millions of research articles.   The library will have subscribed to these journals on your behalf. The smartest thing you can do for accessing research articles is familiarize yourself with your own library.

• If you search a database your library will link from the records to the full text if they have it—all you need to do is click through the links.
• When they do not have a copy of an article, a university library can get it for you from another library. This inter-library loan service is usually free to users.
• Your library might use a browser extension like Lean Library or LibKey Nomad to link you to the library subscription or open access full text from wherever you are on the internet.
• Google Scholar lets you configure your account to get links straight to your library’s subscription copy of an article.  But remember--side-by-side to library subscriptions for legitimate research, Google Scholar includes links to articles published in predatory and unreliable journals that would be unwise to credit in your own work.  Learn more about predatory journals.

If you are not affiliated with a university library, there are still ways you can successfully—and legally—get the full text of research articles.

2.  Open Access browser extensions  

More and more research is published Open Access as governments around the world are mandating that research paid for by taxpayer money be freely available to those taxpayers.

Browser extensions have been created to make it easy to spot when the full text of an article is free.   Some of the best are CORE Discovery , Unpaywall and Open Access Button .

Learn more about difference between discovery and access and why it matters for good research: Where to search - Best Practice for Literature Searching - LibGuides at IFIS

3. Google Scholar

You can search the article title inside quotation marks on Google Scholar to see if a link to a copy of the article appears.   If it does, be sure to pay attention to what version of the article you are linking to, to be sure you are getting what you think you’re getting.  These links can lead to an article's published version of record, a manuscript version, or to a thesis or conference proceeding with the same title and author as the article you expected to find.   

4.  Researcher platforms

 A Google Scholar search might lead you to a researcher platform like Academia.edu or ResearchGate .   There, if you set up an account, you can sometimes download or request a copy of the text.  Again, pay attention to which version of the text you get!

5.  Write to the author

If you can’t get a copy by other means, you can write to an article’s corresponding author and (politely!) ask them to send you a copy. Their contact information, usually an email address, will be listed in the information you find about the article, either in a database record for the article or on the publishing journal’s page for it. Many authors are happy to share a copy of their work.

Three bonus ways that might work depending on where you live:

1.  A nearby university library might offer access to articles even if you do not work or study there.

Members of the public are sometimes allowed access to university journal subscriptions through visitor access or a walk-in user service. You usually need to use the collections from a dedicated computer terminal located in a library and may need to make an appointment before you go. Do your research before showing up to make sure you bring the correct documents and equipment (like a flash drive) along.

2.  Try your public library

In some countries, public libraries partner with publishers to give the public access to research articles.   In the UK, for instance, many public libraries participate in the Access to Research scheme, which gives members of the public on-site access to over 30 million academic articles. Contact your local public library to learn what is available to you.

3.  Research4Life

In other countries, your institution might have access to a massive collection of research articles and databases through the publisher/library/United Nations agency initiative Research4Life . Check to see if you already have access, and if not, if your institution might be eligible to join. Membership is only available on an organizational or institutional level.  

Remember —even though you now have a lot of strategies for finding the full text of articles, research should never be led by the articles you can access most easily.

Good research is driven by first figuring out what articles are most relevant to your question and then getting the full text of what you need. One of the best ways to do this is to use a good discipline-specific database, like FSTA for the sciences of food and health.

10 Free Research and Journal Databases

3-minute read

• 6th April 2019

Finding good research can be tough, especially when so much of it is locked behind paywalls . But there are free resources out there if you know where to look. So to help out, we’ve compiled a list of ten free academic search engines and databases that you should check out.

1. Google Scholar

Even if you’ve not used Google Scholar before, you’ll know Google. And, thus, you can probably guess that Google Scholar is a search engine dedicated to academic work. Not everything listed on Google Scholar will be freely available in full. But it is a good place to start if you’re looking for a specific paper, and many papers can be downloaded for free.

CORE is an open research aggregator. This means it works as a search engine for open access research published by organizations from around the world, all of which is available for free. It is also the world’s largest open access aggregator , so it is a very useful resource for researchers!

3. Bielefeld Academic Search Engine (BASE)

Another dedicated academic search engine, BASE offers access to more than 140 million documents from more than 6,000 sources. Around 60% of these documents are open access, and you can filter results to see only research that is available for free online.

4. Directory of Open Access Journals (DOAJ)

The Directory of Open Access Journals (DOAJ) is a database that lists around 12,000 open access journals covering all areas of science, technology, medicine, social science, and the humanities.

PubMed is a search engine maintained by the NCBI, part of the United States National Library of Medicine. It provides access to more than 29 million citations of biomedical research from MEDLINE, life science journals, and online books. The NCBI runs a similar search engine for research in the chemical sciences called PubChem , too, which is also free to use.

6. E-Theses Online Service (EThOS)

Run by the British Library, EThOS is a database of over 500,000 doctoral theses. More than half of these are available for free, either directly via EThOS or via a link to a university website.

7. Social Science Research Network (SSRN)

SSRN is a database for research from the social sciences and humanities, including 846,589 research papers from 426,107 researchers across 30 disciplines. Most of these are available for free, although you may need to sign up as a member (also free) to access some services.

8. WorldWideScience

WorldWideScience is a global academic search engine, providing access to national and international scientific databases from across the globe. One interesting feature is that it offers automatic translation, so users can have search results translated into their preferred language.

9. Semantic Scholar

Semantic Scholar is an “intelligent” academic search engine. It uses machine learning to prioritize the most important research, which can make it easier to find relevant literature. Or, in Semantic Scholar’s own words, it uses influential citations, images, and key phrases to “cut through the clutter.”

10. Public Library of Science (PLOS)

PLOS is an open-access research organization that publishes several journals. But as well as publishing its own research, PLOS is a dedicated advocate for open-access learning. So if you appreciate the search engines and databases we’ve listed here, check out the rest of the PLOS site to find out more about their campaign to enable access to knowledge.

Eight Ways (and More) To Find and Access Research Papers

This blog is part of our Research Smarter series. You’ll discover the various search engines, databases and data repositories to help you along the way. Click on any of the following links for in an in-depth look at how to find relevant research papers, journals , and authors for your next project using the Web of Science™. You can  also check out our ultimate guides here , which include tips to speed up the writing process.

If you’re in the early stages of your research career, you’re likely struggling to learn all you can about your chosen field and evaluate your options. You also need an easy and convenient way to find the right research papers upon which to build your own work and keep you on the proper path toward your goals.

Fortunately, most institutions have access to thousands of journals, so your first step should be to be to check with library staff  and find out what is available via your institutional subscriptions.

For those who may be unfamiliar with other means of access, this blog post – the first in a series devoted to helping you “research smarter” – will provide a sampling of established data sources for scientific research. These include search engines, databases, and data repositories.

Search Engines and Databases

You may have already discovered that the process of searching for research papers offers many choices and scenarios. Some search engines, for example, can be accessed free of charge. Others require a subscription. The latter group generally includes services that index the contents of thousands of published journals, allowing for detailed searches on data fields such as author name, institution, title or keyword, and even funding sources. Because many journals operate on a subscription model too, the process of obtaining full-text versions of papers can be complicated.

On the other hand, a growing number of publishers follow the practice of Open Access (OA) , making their journal content freely available. Similarly, some authors publish their results in the form of preprints, posting them to preprint servers for immediate and free access. These repositories, like indexing services, differ in that some concentrate in a given discipline or broad subject area, while others cover the full range of research.

Search Engines

Following is a brief selection of reputable search engines by which to locate articles relevant to your research.

Google Scholar is a free search engine that provides access to research in multiple disciplines. The sources include academic publishers, universities, online repositories, books, and even judicial opinions from court cases. Based on its indexing, Google Scholar provides citation counts to allow authors and others to track the impact of their work.  

The Directory of Open Access Journals ( DOAJ ) allows users to search and retrieve the article contents of nearly 10,000 OA journals in science, technology, medicine, social sciences, and humanities. All journals must adhere to quality-control standards, including peer review.

PubMed , maintained by the US National Library of Medicine, is a free search engine covering the biomedical and life sciences. Its coverage derives primarily from the MEDLINE database, covering materials as far back as 1951.

JSTOR affords access to more than 12 million journal articles in upwards of 75 disciplines, providing full-text searches of more than 2,000 journals, and access to more than 5,000 OA books.

Selected Databases

The following selection samples a range of resources, including databases which, as discussed above, index the contents of journals either in a given specialty area or the full spectrum of research. Others listed below offer consolidated coverage of multiple databases. Your institution is likely subscribed to a range of research databases, speak to your librarian to see which databases you have access to, and how to go about your search.

Web of Science includes The Web of Science Core Collection, which covers more than 20,000 carefully selected journals, along with books, conference proceedings, and other sources. The indexing also captures citation data, permitting users to follow the thread of an idea or development over time, as well as to track a wide range of research-performance metrics. The Web of Science also features EndNote™ Click , a free browser plugin that offers one-click access to the best available legal and legitimate full-text versions of papers. See here for our ultimate guide to finding relevant research papers on the Web of Science .

Science.gov covers the vast territory of United States federal science, including more than 60 databases and 2,200-plus websites. The many allied agencies whose research is reflected include NASA, the US Department of Agriculture, and the US Environmental Protection Agency.

CiteSeerx is devoted primarily to information and computer science. The database includes a feature called Autonomous Citation Indexing, designed to extract citations and create a citation index for literature searching and evaluation.

Preprint and Data Repositories

An early form of OA literature involved authors, as noted above,  making electronic, preprint versions of their papers freely available. This practice has expanded widely today. You can find archives devoted to a single main specialty area, as well as general repositories connected with universities and other institutions.

The specialty archive is perhaps best exemplified by arXiv (conveniently pronounced “archive,” and one of the earliest examples of a preprint repository). Begun in 1991 as a physics repository, ArXiv has expanded to embrace mathematics, astronomy, statistics, economics, and other disciplines. The success of ArXiv spurred the development of, for example, bioArXiv devoted to an array of topics within biology, and for chemistry, ChemRxiv .

Meanwhile, thousands of institutional repositories hold a variety of useful materials. In addition to research papers, these archives store raw datasets, graphics, notes, and other by-products of investigation. Currently, the Registry of Open Access Repositories lists more than 4,700 entries.

Reach Out Yourself?

If the resources above don’t happen to result in a free and full-text copy of the research you seek, you can also try reaching out to the authors yourself.

To find who authored a paper, you can search indexing platforms like the Web of Science , or research profiling systems like Publons™ , or ResearchGate , then look to reach out to the authors directly.

So, although the sheer volume of research can pose a challenge to identifying and securing needed papers, plenty of options are available.

How To Write A Research Paper

Step-By-Step Tutorial With Examples + FREE Template

By: Derek Jansen (MBA) | Expert Reviewer: Dr Eunice Rautenbach | March 2024

For many students, crafting a strong research paper from scratch can feel like a daunting task – and rightly so! In this post, we’ll unpack what a research paper is, what it needs to do , and how to write one – in three easy steps. 🙂 

Overview: Writing A Research Paper

What (exactly) is a research paper.

• How to write a research paper
• Stage 1 : Topic & literature search
• Stage 2 : Structure & outline
• Stage 3 : Iterative writing
• Key takeaways

Let’s start by asking the most important question, “ What is a research paper? ”.

Simply put, a research paper is a scholarly written work where the writer (that’s you!) answers a specific question (this is called a research question ) through evidence-based arguments . Evidence-based is the keyword here. In other words, a research paper is different from an essay or other writing assignments that draw from the writer’s personal opinions or experiences. With a research paper, it’s all about building your arguments based on evidence (we’ll talk more about that evidence a little later).

Now, it’s worth noting that there are many different types of research papers , including analytical papers (the type I just described), argumentative papers, and interpretative papers. Here, we’ll focus on analytical papers , as these are some of the most common – but if you’re keen to learn about other types of research papers, be sure to check out the rest of the blog .

With that basic foundation laid, let’s get down to business and look at how to write a research paper .

Overview: The 3-Stage Process

While there are, of course, many potential approaches you can take to write a research paper, there are typically three stages to the writing process. So, in this tutorial, we’ll present a straightforward three-step process that we use when working with students at Grad Coach.

These three steps are:

• Finding a research topic and reviewing the existing literature
• Developing a provisional structure and outline for your paper, and
• Writing up your initial draft and then refining it iteratively

Let’s dig into each of these.

Need a helping hand?

Step 1: Find a topic and review the literature

As we mentioned earlier, in a research paper, you, as the researcher, will try to answer a question . More specifically, that’s called a research question , and it sets the direction of your entire paper. What’s important to understand though is that you’ll need to answer that research question with the help of high-quality sources – for example, journal articles, government reports, case studies, and so on. We’ll circle back to this in a minute.

The first stage of the research process is deciding on what your research question will be and then reviewing the existing literature (in other words, past studies and papers) to see what they say about that specific research question. In some cases, your professor may provide you with a predetermined research question (or set of questions). However, in many cases, you’ll need to find your own research question within a certain topic area.

Finding a strong research question hinges on identifying a meaningful research gap – in other words, an area that’s lacking in existing research. There’s a lot to unpack here, so if you wanna learn more, check out the plain-language explainer video below.

Once you’ve figured out which question (or questions) you’ll attempt to answer in your research paper, you’ll need to do a deep dive into the existing literature – this is called a “ literature search ”. Again, there are many ways to go about this, but your most likely starting point will be Google Scholar .

If you’re new to Google Scholar, think of it as Google for the academic world. You can start by simply entering a few different keywords that are relevant to your research question and it will then present a host of articles for you to review. What you want to pay close attention to here is the number of citations for each paper – the more citations a paper has, the more credible it is (generally speaking – there are some exceptions, of course).

Ideally, what you’re looking for are well-cited papers that are highly relevant to your topic. That said, keep in mind that citations are a cumulative metric , so older papers will often have more citations than newer papers – just because they’ve been around for longer. So, don’t fixate on this metric in isolation – relevance and recency are also very important.

Beyond Google Scholar, you’ll also definitely want to check out academic databases and aggregators such as Science Direct, PubMed, JStor and so on. These will often overlap with the results that you find in Google Scholar, but they can also reveal some hidden gems – so, be sure to check them out.

Once you’ve worked your way through all the literature, you’ll want to catalogue all this information in some sort of spreadsheet so that you can easily recall who said what, when and within what context. If you’d like, we’ve got a free literature spreadsheet that helps you do exactly that.

Step 2: Develop a structure and outline

With your research question pinned down and your literature digested and catalogued, it’s time to move on to planning your actual research paper .

It might sound obvious, but it’s really important to have some sort of rough outline in place before you start writing your paper. So often, we see students eagerly rushing into the writing phase, only to land up with a disjointed research paper that rambles on in multiple

Now, the secret here is to not get caught up in the fine details . Realistically, all you need at this stage is a bullet-point list that describes (in broad strokes) what you’ll discuss and in what order. It’s also useful to remember that you’re not glued to this outline – in all likelihood, you’ll chop and change some sections once you start writing, and that’s perfectly okay. What’s important is that you have some sort of roadmap in place from the start.

At this stage you might be wondering, “ But how should I structure my research paper? ”. Well, there’s no one-size-fits-all solution here, but in general, a research paper will consist of a few relatively standardised components:

• Introduction
• Literature review
• Methodology

Let’s take a look at each of these.

First up is the introduction section . As the name suggests, the purpose of the introduction is to set the scene for your research paper. There are usually (at least) four ingredients that go into this section – these are the background to the topic, the research problem and resultant research question , and the justification or rationale. If you’re interested, the video below unpacks the introduction section in more detail. 

The next section of your research paper will typically be your literature review . Remember all that literature you worked through earlier? Well, this is where you’ll present your interpretation of all that content . You’ll do this by writing about recent trends, developments, and arguments within the literature – but more specifically, those that are relevant to your research question . The literature review can oftentimes seem a little daunting, even to seasoned researchers, so be sure to check out our extensive collection of literature review content here .

With the introduction and lit review out of the way, the next section of your paper is the research methodology . In a nutshell, the methodology section should describe to your reader what you did (beyond just reviewing the existing literature) to answer your research question. For example, what data did you collect, how did you collect that data, how did you analyse that data and so on? For each choice, you’ll also need to justify why you chose to do it that way, and what the strengths and weaknesses of your approach were.

Now, it’s worth mentioning that for some research papers, this aspect of the project may be a lot simpler . For example, you may only need to draw on secondary sources (in other words, existing data sets). In some cases, you may just be asked to draw your conclusions from the literature search itself (in other words, there may be no data analysis at all). But, if you are required to collect and analyse data, you’ll need to pay a lot of attention to the methodology section. The video below provides an example of what the methodology section might look like.

By this stage of your paper, you will have explained what your research question is, what the existing literature has to say about that question, and how you analysed additional data to try to answer your question. So, the natural next step is to present your analysis of that data . This section is usually called the “results” or “analysis” section and this is where you’ll showcase your findings.

Depending on your school’s requirements, you may need to present and interpret the data in one section – or you might split the presentation and the interpretation into two sections. In the latter case, your “results” section will just describe the data, and the “discussion” is where you’ll interpret that data and explicitly link your analysis back to your research question. If you’re not sure which approach to take, check in with your professor or take a look at past papers to see what the norms are for your programme.

Alright – once you’ve presented and discussed your results, it’s time to wrap it up . This usually takes the form of the “ conclusion ” section. In the conclusion, you’ll need to highlight the key takeaways from your study and close the loop by explicitly answering your research question. Again, the exact requirements here will vary depending on your programme (and you may not even need a conclusion section at all) – so be sure to check with your professor if you’re unsure.

Step 3: Write and refine

Finally, it’s time to get writing. All too often though, students hit a brick wall right about here… So, how do you avoid this happening to you?

Well, there’s a lot to be said when it comes to writing a research paper (or any sort of academic piece), but we’ll share three practical tips to help you get started.

First and foremost , it’s essential to approach your writing as an iterative process. In other words, you need to start with a really messy first draft and then polish it over multiple rounds of editing. Don’t waste your time trying to write a perfect research paper in one go. Instead, take the pressure off yourself by adopting an iterative approach.

Secondly , it’s important to always lean towards critical writing , rather than descriptive writing. What does this mean? Well, at the simplest level, descriptive writing focuses on the “ what ”, while critical writing digs into the “ so what ” – in other words, the implications. If you’re not familiar with these two types of writing, don’t worry! You can find a plain-language explanation here.

Last but not least, you’ll need to get your referencing right. Specifically, you’ll need to provide credible, correctly formatted citations for the statements you make. We see students making referencing mistakes all the time and it costs them dearly. The good news is that you can easily avoid this by using a simple reference manager . If you don’t have one, check out our video about Mendeley, an easy (and free) reference management tool that you can start using today.

Recap: Key Takeaways

We’ve covered a lot of ground here. To recap, the three steps to writing a high-quality research paper are:

• To choose a research question and review the literature
• To plan your paper structure and draft an outline
• To take an iterative approach to writing, focusing on critical writing and strong referencing

Students Are Likely Writing Millions of Papers With AI

Students have submitted more than 22 million papers that may have used generative AI in the past year, new data released by plagiarism detection company Turnitin shows.

A year ago, Turnitin rolled out an AI writing detection tool that was trained on its trove of papers written by students as well as other AI-generated texts. Since then, more than 200 million papers have been reviewed by the detector, predominantly written by high school and college students. Turnitin found that 11 percent may contain AI-written language in 20 percent of its content, with 3 percent of the total papers reviewed getting flagged for having 80 percent or more AI writing. (Turnitin is owned by Advance, which also owns Condé Nast, publisher of WIRED.) Turnitin says its detector has a false positive rate of less than 1 percent when analyzing full documents.

ChatGPT’s launch was met with knee-jerk fears that the English class essay would die . The chatbot can synthesize information and distill it near-instantly—but that doesn’t mean it always gets it right. Generative AI has been known to hallucinate , creating its own facts and citing academic references that don’t actually exist. Generative AI chatbots have also been caught spitting out biased text on gender and race . Despite those flaws, students have used chatbots for research, organizing ideas, and as a ghostwriter . Traces of chatbots have even been found in peer-reviewed, published academic writing .

Teachers understandably want to hold students accountable for using generative AI without permission or disclosure. But that requires a reliable way to prove AI was used in a given assignment. Instructors have tried at times to find their own solutions to detecting AI in writing, using messy, untested methods to enforce rules , and distressing students. Further complicating the issue, some teachers are even using generative AI in their grading processes.

Detecting the use of gen AI is tricky. It’s not as easy as flagging plagiarism, because generated text is still original text. Plus, there’s nuance to how students use gen AI; some may ask chatbots to write their papers for them in large chunks or in full, while others may use the tools as an aid or a brainstorm partner.

Students also aren't tempted by only ChatGPT and similar large language models. So-called word spinners are another type of AI software that rewrites text, and may make it less obvious to a teacher that work was plagiarized or generated by AI. Turnitin’s AI detector has also been updated to detect word spinners, says Annie Chechitelli, the company’s chief product officer. It can also flag work that was rewritten by services like spell checker Grammarly, which now has its own generative AI tool . As familiar software increasingly adds generative AI components, what students can and can’t use becomes more muddled.

Detection tools themselves have a risk of bias. English language learners may be more likely to set them off; a 2023 study found a 61.3 percent false positive rate when evaluating Test of English as a Foreign Language (TOEFL) exams with seven different AI detectors. The study did not examine Turnitin’s version. The company says it has trained its detector on writing from English language learners as well as native English speakers. A study published in October found that Turnitin was among the most accurate of 16 AI language detectors in a test that had the tool examine undergraduate papers and AI-generated papers.

Schools that use Turnitin had access to the AI detection software for a free pilot period, which ended at the start of this year. Chechitelli says a majority of the service’s clients have opted to purchase the AI detection. But the risks of false positives and bias against English learners have led some universities to ditch the tools for now. Montclair State University in New Jersey announced in November that it would pause use of Turnitin’s AI detector. Vanderbilt University and Northwestern University did the same last summer.

“This is hard. I understand why people want a tool,” says Emily Isaacs, executive director of the Office of Faculty Excellence at Montclair State. But Isaacs says the university is concerned about potentially biased results from AI detectors, as well as the fact that the tools can’t provide confirmation the way they can with plagiarism. Plus, Montclair State doesn’t want to put a blanket ban on AI, which will have some place in academia. With time and more trust in the tools, the policies could change. “It’s not a forever decision, it’s a now decision,” Isaacs says.

Chechitelli says the Turnitin tool shouldn’t be the only consideration in passing or failing a student. Instead, it’s a chance for teachers to start conversations with students that touch on all of the nuance in using generative AI. “People don’t really know where that line should be,” she says.

Key facts about the abortion debate in America

The U.S. Supreme Court’s June 2022 ruling to overturn Roe v. Wade – the decision that had guaranteed a constitutional right to an abortion for nearly 50 years – has shifted the legal battle over abortion to the states, with some prohibiting the procedure and others moving to safeguard it.

As the nation’s post-Roe chapter begins, here are key facts about Americans’ views on abortion, based on two Pew Research Center polls: one conducted from June 25-July 4 , just after this year’s high court ruling, and one conducted in March , before an earlier leaked draft of the opinion became public.

This analysis primarily draws from two Pew Research Center surveys, one surveying 10,441 U.S. adults conducted March 7-13, 2022, and another surveying 6,174 U.S. adults conducted June 27-July 4, 2022. Here are the questions used for the March survey , along with responses, and the questions used for the survey from June and July , along with responses.

Everyone who took part in these surveys is a member of the Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses. This way nearly all U.S. adults have a chance of selection. The survey is weighted to be representative of the U.S. adult population by gender, race, ethnicity, partisan affiliation, education and other categories.  Read more about the ATP’s methodology .

A majority of the U.S. public disapproves of the Supreme Court’s decision to overturn Roe. About six-in-ten adults (57%) disapprove of the court’s decision that the U.S. Constitution does not guarantee a right to abortion and that abortion laws can be set by states, including 43% who strongly disapprove, according to the summer survey. About four-in-ten (41%) approve, including 25% who strongly approve.

About eight-in-ten Democrats and Democratic-leaning independents (82%) disapprove of the court’s decision, including nearly two-thirds (66%) who strongly disapprove. Most Republicans and GOP leaners (70%) approve , including 48% who strongly approve.

Most women (62%) disapprove of the decision to end the federal right to an abortion. More than twice as many women strongly disapprove of the court’s decision (47%) as strongly approve of it (21%). Opinion among men is more divided: 52% disapprove (37% strongly), while 47% approve (28% strongly).

About six-in-ten Americans (62%) say abortion should be legal in all or most cases, according to the summer survey – little changed since the March survey conducted just before the ruling. That includes 29% of Americans who say it should be legal in all cases and 33% who say it should be legal in most cases. About a third of U.S. adults (36%) say abortion should be illegal in all (8%) or most (28%) cases.

Generally, Americans’ views of whether abortion should be legal remained relatively unchanged in the past few years , though support fluctuated somewhat in previous decades.

Relatively few Americans take an absolutist view on the legality of abortion – either supporting or opposing it at all times, regardless of circumstances. The March survey found that support or opposition to abortion varies substantially depending on such circumstances as when an abortion takes place during a pregnancy, whether the pregnancy is life-threatening or whether a baby would have severe health problems.

While Republicans’ and Democrats’ views on the legality of abortion have long differed, the 46 percentage point partisan gap today is considerably larger than it was in the recent past, according to the survey conducted after the court’s ruling. The wider gap has been largely driven by Democrats: Today, 84% of Democrats say abortion should be legal in all or most cases, up from 72% in 2016 and 63% in 2007. Republicans’ views have shown far less change over time: Currently, 38% of Republicans say abortion should be legal in all or most cases, nearly identical to the 39% who said this in 2007.

However, the partisan divisions over whether abortion should generally be legal tell only part of the story. According to the March survey, sizable shares of Democrats favor restrictions on abortion under certain circumstances, while majorities of Republicans favor abortion being legal in some situations , such as in cases of rape or when the pregnancy is life-threatening.

There are wide religious divides in views of whether abortion should be legal , the summer survey found. An overwhelming share of religiously unaffiliated adults (83%) say abortion should be legal in all or most cases, as do six-in-ten Catholics. Protestants are divided in their views: 48% say it should be legal in all or most cases, while 50% say it should be illegal in all or most cases. Majorities of Black Protestants (71%) and White non-evangelical Protestants (61%) take the position that abortion should be legal in all or most cases, while about three-quarters of White evangelicals (73%) say it should be illegal in all (20%) or most cases (53%).

In the March survey, 72% of White evangelicals said that the statement “human life begins at conception, so a fetus is a person with rights” reflected their views extremely or very well . That’s much greater than the share of White non-evangelical Protestants (32%), Black Protestants (38%) and Catholics (44%) who said the same. Overall, 38% of Americans said that statement matched their views extremely or very well.

Catholics, meanwhile, are divided along religious and political lines in their attitudes about abortion, according to the same survey. Catholics who attend Mass regularly are among the country’s strongest opponents of abortion being legal, and they are also more likely than those who attend less frequently to believe that life begins at conception and that a fetus has rights. Catholic Republicans, meanwhile, are far more conservative on a range of abortion questions than are Catholic Democrats.

Women (66%) are more likely than men (57%) to say abortion should be legal in most or all cases, according to the survey conducted after the court’s ruling.

More than half of U.S. adults – including 60% of women and 51% of men – said in March that women should have a greater say than men in setting abortion policy . Just 3% of U.S. adults said men should have more influence over abortion policy than women, with the remainder (39%) saying women and men should have equal say.

The March survey also found that by some measures, women report being closer to the abortion issue than men . For example, women were more likely than men to say they had given “a lot” of thought to issues around abortion prior to taking the survey (40% vs. 30%). They were also considerably more likely than men to say they personally knew someone (such as a close friend, family member or themselves) who had had an abortion (66% vs. 51%) – a gender gap that was evident across age groups, political parties and religious groups.

Relatively few Americans view the morality of abortion in stark terms , the March survey found. Overall, just 7% of all U.S. adults say having an abortion is morally acceptable in all cases, and 13% say it is morally wrong in all cases. A third say that having an abortion is morally wrong in most cases, while about a quarter (24%) say it is morally acceptable in most cases. An additional 21% do not consider having an abortion a moral issue.

Among Republicans, most (68%) say that having an abortion is morally wrong either in most (48%) or all cases (20%). Only about three-in-ten Democrats (29%) hold a similar view. Instead, about four-in-ten Democrats say having an abortion is morally  acceptable  in most (32%) or all (11%) cases, while an additional 28% say it is not a moral issue. 

White evangelical Protestants overwhelmingly say having an abortion is morally wrong in most (51%) or all cases (30%). A slim majority of Catholics (53%) also view having an abortion as morally wrong, but many also say it is morally acceptable in most (24%) or all cases (4%), or that it is not a moral issue (17%). Among religiously unaffiliated Americans, about three-quarters see having an abortion as morally acceptable (45%) or not a moral issue (32%).

Harvard and Caltech Will Require Test Scores for Admission

The universities are the latest highly selective schools to end their policies that made submitting SAT or ACT scores optional.

By Anemona Hartocollis and Stephanie Saul

Harvard will reinstate standardized testing as a requirement of admission, the university announced Thursday, becoming the latest in a series of highly competitive universities to reverse their test-optional policies.

Students applying to enter Harvard in fall 2025 and beyond will be required to submit SAT or ACT scores, though the university said a few other test scores will be accepted in “exceptional cases,” including Advanced Placement or International Baccalaureate tests. The university had previously said it was going to keep its test-optional policy through the entering class of fall 2026.

Within hours of Harvard’s announcement, Caltech, a science and engineering institute, also said it was reinstating its testing requirements for students applying for admission in fall 2025.

The schools had been among nearly 2,000 colleges across the country that dropped test score requirements over the last few years, a trend that escalated during the pandemic when it was harder for students to get to test sites.

Dropping test score requirements was widely viewed as a tool to help diversify admissions, by encouraging poor and underrepresented students who had potential but did not score well on the tests to apply. But supporters of the tests have said without scores, it became harder to identify promising students who outperformed in their environments.

In explaining its decision to accelerate the return to testing, Harvard cited a study by Opportunity Insights , which found that test scores were a better predictor of academic success in college than high school grades and that they can help admissions officers identify highly talented students from low income groups who might otherwise had gone unnoticed.

“Standardized tests are a means for all students, regardless of their background and life experience, to provide information that is predictive of success in college and beyond,” Hopi Hoekstra, dean of the faculty of arts and sciences, said in a statement announcing the move.

“In short, more information, especially such strongly predictive information, is valuable for identifying talent from across the socioeconomic range,” she added.

Caltech, in Pasadena, Calif., said that reinstating testing requirements reaffirmed the school’s “commitment as a community of scientists and engineers to using all relevant data in its decision-making processes.”

Harvard and Caltech join a growing number of schools, notable for their selectivity, that have since reversed their policies, including Brown, Yale, Dartmouth, M.I.T., Georgetown, Purdue and the University of Texas at Austin.

For Harvard, the move comes at a time of transition, and perhaps a return to more conservative policies.

Last June, the Supreme Court struck down race-conscious college admissions in cases involving Harvard and the University of North Carolina, raising fears that with the demise of affirmative action, those schools would become less diverse.

And in January, Harvard’s first Black president, Claudine Gay, resigned under pressure from critics who said she had not acted strongly enough to combat antisemitism on campus after the Oct. 7 attack by Hamas on Israel, and under mounting accusations of plagiarism in her academic work, which she stood by.

The provost, Alan Garber, was named interim president, while the dean of the law school, John Manning, became interim provost, the university’s second-highest administrative position. Mr. Manning is considered a strong potential candidate to replace Dr. Gay. His background stands out for his conservative associations, having clerked for the former Supreme Court justice Antonin Scalia.

In the current climate on campus, a return to test scores could be seen as a return to tradition. It also may address concerns of many parents that the college admissions process, especially in elite institutions, is inscrutable and disconnected from merit.

Applications to Harvard were down by 5 percent this year, while those at many of its peer universities went up, suggesting that the recent turmoil may have dented its reputation. But it still received a staggering number of undergraduate applications — 54,008 — and admitted only 3.6 percent. Requiring test scores could make sorting through applications more manageable.

Critics of standardized tests have long raised concerns that the tests helped fuel inequality because some wealthier students raised their scores through high-priced tutoring. But recent studies have found that test scores help predict college grades, chances of graduation and post-college success, and that test scores are more reliable than high school grades, partly because of grade inflation in recent years .

But Robert Schaeffer, director of public education at FairTest, an organization that opposes standardized testing, said Thursday that the Opportunity Insights analysis had been criticized by other researchers. “Those scholars say that when you eliminate the role of wealth, test scores are not better than high school G.P.A.,” he said, adding that it is not clear whether that pattern is true among the admissions pool at super selective colleges such as Harvard.

Mr. Schaeffer said that at least 1,850 universities remain test optional, including Michigan, Vanderbilt, Wisconsin and Syracuse, which have recently extended their policies. “The vast majority of colleges will not require test scores.” An exception, he said, could be the University of North Carolina system, which is considering a plan to require tests, but only for those students with a G.P.A. below 2.8.

Acknowledging the concerns of critics, Harvard said that it would reassess the new policy regularly. The school said that test scores would be considered along with other information about an applicant’s experience, skills, talents, contributions to communities and references. They will also be looked at in the context of how other students are doing at the same high school.

“Admissions officers understand that not all students attend well-resourced schools, and those who come from modest economic backgrounds or first-generation college families may have had fewer opportunities to prepare for standardized tests,” William R. Fitzsimmons, Harvard’s dean of admissions and financial aid, said in a statement.

Harvard said that in the interest of selecting a diverse student body, it has enhanced financial aid and stepped up recruitment of underserved students by joining a consortium of 30 public and private universities that recruits students from rural communities.

An earlier version of this article misstated Robert Schaeffer’s position. He is the director of public education at FairTest, not the director.
