21 Legit Research Databases for Free Journal Articles in 2024

#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 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.

Open research reports

JSTOR hosts a growing curated collection of more than 50,000 open research reports from 187 think tanks and research institutes from around the world. These publications are freely accessible to everyone on JSTOR and discoverable as their own content type alongside journals, books, and primary sources. We update research reports on our platform each month as they become available through contributing institutes.

Download the list (xlsx) of contributing policy institutes.

Research reports provide current analysis on many of today’s most discussed and debated issues from a diversity of ideological and international perspectives representing 40 countries and 29 languages. A sample of topics would include: climate change, border security, fake news, cybersecurity, electric vehicles, artificial intelligence, energy policy, gender issues, terrorism, remote learning, recent trends in business and economics, and various public health issues, including COVID-19.

Although the briefs, papers, and reports published by these institutes are not peer-reviewed, they are written by policy experts and members of the academic community who are fellows in residence. This is content that impacts policy, both foreign and domestic. It is also increasingly used by faculty in their classrooms for its currency, breadth, and accessibility.

JSTOR’s research reports cover seven Areas of Focus: Business & Economics, Critical Race & Ethnic Studies, Education, Gender & Sexuality, Public Health, Security Studies, and Sustainability.

Why research reports on JSTOR?

Input from faculty and librarians revealed that although research reports were for the most part freely available outside of JSTOR, they were hard to find and not easily discoverable alongside relevant material. It was also difficult for students to differentiate between the most credible research reports and a growing corpus of questionable sources on the Web.

JSTOR has attempted to redress these issues by centralizing a curated collection of think tank research reports on a single platform, making this content freely available to all JSTOR users, and enhancing its discoverability through comprehensive searching and the application of rich metadata.

Search Help

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.

Anne Author , John Doe , Jane Smith , Someone Else

In this fascinating paper, we investigate various topics that would be of interest to you. We also describe new methods relevant to your project, and attempt to address several questions which you would also like to know the answer to. Lastly, we analyze …

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."

Unlocking knowledge: your gateway to open access scientific papers and research data, introduction.

In the digital era, the quest for knowledge and scientific discovery is no longer confined to the walls of academia and research institutions. Welcome to [Your Website Name] , a dedicated platform for finding and downloading open access scientific papers and other research data. Our mission is to democratize access to scientific information, making it freely available to researchers, students, and curious minds across the globe.

What is Open Access?

Open Access (OA) refers to the practice of providing unrestricted access via the Internet to peer-reviewed scholarly research. OA content is available to all, without the usual financial or legal barriers. We believe that open access is crucial in fostering a culture of knowledge sharing and collaboration, thereby accelerating innovation and discovery.

Types of Open Access:

• Gold Open Access: Papers are published in open access journals that provide immediate open access to all of their articles.
• Green Open Access (Self-Archiving): Authors publish in any journal and then self-archive a version of the article for free public use in their institutional repository or on a website.
• Hybrid Open Access: Some articles in a subscription journal are made open access upon the payment of an additional charge.

Downloading Resources

• Direct Downloads: Once you find a paper or dataset, download it directly.
• Citation Tools: Easily export citations in various formats to incorporate them into your research.

Open Access

Open access in scientific publishing represents a transformative approach that breaks down traditional barriers to knowledge dissemination. It is a movement dedicated to making scientific research freely available to all, fostering a more inclusive and collaborative scientific community. At its core, open access allows for the unrestricted sharing of research findings, enabling scientists, academicians, and the general public to access and utilize scientific papers without the constraints of subscription fees or licensing restrictions. This paradigm shift in scholarly communication is driven by the belief that knowledge, particularly that which is publicly funded, should be a communal resource, accessible to everyone for the greater good of society.

In the realm of scientific research, open access has numerous advantages. It accelerates the pace of discovery by allowing researchers to build upon existing work without delay, facilitating interdisciplinary collaboration and cross-pollination of ideas across various fields. This is particularly crucial in addressing global challenges, where rapid and unencumbered access to research can lead to faster solutions. Furthermore, open access democratizes knowledge by making it available to researchers in developing countries who may not have the resources for expensive journal subscriptions, thereby narrowing the research gap between high and low-income countries.

The open access model also aligns with the digital age's ethos of openness and transparency. It enables a more efficient validation and critique process, as a larger audience can scrutinize and contribute to the research. This can lead to higher quality and more reliable scientific work. Moreover, it provides an equal platform for emerging researchers and institutions to share their findings, ensuring that the visibility and impact of research are not confined to those within well-funded, prestigious entities.

However, the transition to open access is not without challenges. The sustainability of publishing models, quality assurance, and equitable distribution of costs are ongoing concerns. Despite these hurdles, the open access movement is gaining momentum, driven by the global scientific community's commitment to an open, accessible, and collaborative future in research. As we move forward, open access stands as a beacon of progress, symbolizing a world where knowledge is a shared and freely accessible asset, driving innovation and societal advancement.

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.

Find this useful?

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.

Japan’s push to make all research open access is taking shape

Japan plans to make all publicly funded research available to read in institutional repositories. Credit: Toru Yamanaka/AFP via Getty

The Japanese government is pushing ahead with a plan to make Japan’s publicly funded research output free to read. In June, the science ministry will assign funding to universities to build the infrastructure needed to make research papers free to read on a national scale. The move follows the ministry’s announcement in February that researchers who receive government funding will be required to make their papers freely available to read on the institutional repositories from April 2025.

The Japanese plan “is expected to enhance the long-term traceability of research information, facilitate secondary research and promote collaboration”, says Kazuki Ide, a health-sciences and public-policy scholar at Osaka University in Suita, Japan, who has written about open access in Japan .

The nation is one of the first Asian countries to make notable advances towards making more research open access (OA) and among the first countries in the world to forge a nationwide plan for OA.

The plan follows in the footsteps of the influential Plan S, introduced six years ago by a group of research funders in the United States and Europe known as cOAlition S , to accelerate the move to OA publishing . The United States also implemented an OA mandate in 2022 that requires all research funded by US taxpayers to be freely available from 2026.

Institutional repositories

When the Ministry of Education, Culture, Sports, Science and Technology (MEXT) announced Japan’s pivot to OA in February, it also said that it would invest ¥10 billion (around US$63 million) to standardize institutional repositories — websites dedicated to hosting scientific papers, their underlying data and other materials — ensuring that there will be a mechanism for making research in Japan open.

Among the roughly 800 universities in Japan, more than 750 already have an institutional repository, says Shimasaki Seiichi, director of the Research and Development Bureau at MEXT in Tokyo, who was involved with drawing up the plan. Each university will host the research produced by its academics, but the underlying software will be the same.

In 2022, Japan also launched its own national preprint server, Jxiv , but its use remains limited, with only a few hundred preprint articles posted on the platform so far. Ide says that publishing as preprints is not yet habitual for many researchers in Japan, noting that only around one in five respondents to his 2023 survey 1 on Jxiv were even aware that it existed.

Japan’s move to greater access to its research is focusing on ‘green OA’ — in which authors make the author-accepted, but unfinalized, versions of papers available in the digital repositories, says Seiichi.

Seiichi says that gold OA — in which the final copyedited and polished version of a paper is made freely available on the journal site — is not feasible on a wide scale. That’s because the cost to make every paper free to read would be too high for universities. Publishers levy an article-processing charge (APC) if the paper is made free to read, rather than being paywalled, a fee that covers a publisher’s costs.

APCs are increasing at an average rate of 4.3% per year, notes Johan Rooryck, a scholar of French linguistics at Leiden University in the Netherlands, and executive director of cOAlition S.

Rooryck says that Japan’s green OA strategy should be applauded. “It’s definitely something that one should do,” he says. “Especially for all the content that is still behind the paywall.”

Kathleen Shearer, executive director of the Confederation of Open Access Repositories in Montreal, Canada, says that the Japanese plan is “equitable”.

“It doesn’t matter where you publish, whether you have APCs or not, you are still able to comply with an open-access policy,” she says.

She adds that the policy will mean that Japan has a unified record of all research produced by its academics, because all institutional repositories are hosted on the same national server. “Japan is way ahead of the rest of us,” Shearer says. “More countries are moving in this direction but Japan really was one of the first.”

Focusing on institutional repositories will have another benefit: it will not discriminate against research published in Japanese, Shearer says. “A big part of their scholarly ecosystem is represented in Japanese.”

Japanese research is no longer world class — here’s why

The plan to move to OA and support Japanese universities’ repositories comes as Japan grapples with its declining standing in international research.

In a report released last October, MEXT found that Japan’s world-class research status is declining . For instance, Japan’s share in the top 10% of most-cited papers has dipped from 6% to 2%, placing it 13th on the list of nations, despite Japan having the 5th-highest research output.

In March, Japan vowed to triple its number of doctorate holders by 2040, after another report found that the country’s number of PhD graduates is also declining, making it an outlier among the major economies.
