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.

Sci-Hub is the most controversial project in today science. The goal of Sci-Hub is to provide free and unrestricted access to all scientific knowledge ever published in journal or book form.

Today the circulation of knowledge in science is restricted by high prices. Many students and researchers cannot afford academic journals and books that are locked behind paywalls. Sci-Hub emerged in 2011 to tackle this problem. Since then, the website has revolutionized the way science is being done.

Sci-Hub is helping millions of students and researchers, medical professionals, journalists and curious people in all countries to unlock access to knowledge. The mission of Sci-Hub is to fight every obstacle that prevents open access to knowledge: be it legal, technical or otherwise.

How to Access Journal Articles Behind Paywalls

Science can’t advance without researchers being able to share their publications with collaborators and others and to access published papers as bases for their own hypotheses and work. The trend toward open-access availability of papers and the push for mandating publicly-funded research to be freely accessible to the public is still ongoing [1,2]. Until more literature is easily accessible, the path from the publication of an article to the eyes of a researcher in need of it is not always straightforward.

In this first of a two-part series, we review legal ways to access journal articles . Look out for our upcoming article on sharing your articles.

Access Journal Articles Behind Paywalls for Free

It’s an all-too-familiar frustration: you’re writing your latest research paper and sifting through PubMed [3] for sources to cite, and you come across an abstract where the authors describe experiments that would confirm or deny your burgeoning point…only to hit a paywall.

Another common dilemma: it’s your turn to lead journal club, and you want to cover the latest major publication on the gene many members of your group are researching, but like many just-published papers, it’s paywalled for the next 12 months.

How can you dig deeper to support your manuscript properly, or nab access to that hot new paper for group discussion, without paying the usually hefty single-article fee [4]…or breaking the law?

Check Your Institutions’ and Associations’ Subscriptions

Universities, colleges, and companies usually subscribe to a number of journals relevant to their research. You might have hit a paywall simply because you’re not logged in through your institution. If you’re on-site, check your internet connection. Your Wi-Fi device might have reverted to guest access that lacks privileges afforded to students, faculty, and staff of the institution, a common glitch.

If you’re working from home, have you logged in to your institution’s VPN or library proxy server? Some papers (especially older ones) that are not available via PubMed even when you log in through VPN or proxy could still be available through your university’s library. Clicking around on the library’s site often reveals different ranges of issue dates sorted under different databases, particularly for long-running journals.

Institutions where you are an alumnus could also be helpful here. Many universities include some extent of library access—often for a small annual fee—in their alumni programs. It’s frequently limited to physical copies or to a single database that is separate from the greater variety available to current students, but it could just uncover that specific article you seek.

Finally, are you a member of the Biophysical Society, AAAS, ASBMB [5,6,7], or other science society? These usually offer free or discounted subscriptions to the journals they publish.

Investigate Other Library Options

Your local library might subscribe to the journal(s) you’re trying to access. In many cases, the resources are only available on microfilm or microfiche.

And don’t forget good old interlibrary loans. It will take a few visits to websites of libraries where you aren’t a member and maybe a few phone calls as well, just to see which library has the right issue of the journal. Then, call your institution’s or city’s library and arrange for a loan from that other library. This may cost a nominal fee and may only allow you access to a hard copy. Also, keep in mind how soon you need the resource, as interlibrary loans often take weeks.

Get it From the Author

The first page of most papers contains an email address for the corresponding author for situations exactly like this! Contact info is also available on that webpage with the abstract preceding the page with the paywall. It might feel awkward to cold-email a researcher you don’t know for their paper, but if they respond, it would be all worthwhile.

Be sure to ask the author about any permission they have from the journal to share the paper, and give them the chance to check with the journal as they might also not know. (You could also look on How Can I Share It whether an author is allowed to share their work [8].) In many cases, journals give authors permission to share only pre-print versions of their papers, which suit most purposes and shouldn’t inhibit your work that uses that paper.

If you write to the corresponding author and can’t seem to get a response, check the authors’ lab group pages on their institutions’ websites as well as their social media pages. Some publishers, such as Springer Nature [9], are allowing authors to share their work, often in view-only mode, on social media, networks for researchers, personal websites, and public repositories without it being a copyright violation.

Try Unpaywall

Unpaywall [10], a service from the organization Our Research (formerly Impactstory) [11,12], legally harvests content from open-access sources such as university and government databases and authors’ and publishers’ webpages and makes them available in one place [13].

While there isn’t a search bar on its site to look for papers directly, it is integrated into Dimensions [14] and Scopus [15], where its database feeds into your search results [16]. If you’re accessing the web from a University of California campus or through their VPN or proxy, you’ll see Unpaywall as a link for accessing many of your search results. Otherwise, you may want to install Unpaywall as a browser plug-in; it’s available for Chrome [17] and Firefox [18]. It runs in the background while you browse, without the need for you to paste in article DOIs as in its previous iteration, OA Button (which is still available [19]).

Look for an Open-Access Alternative

Are you looking for an article to cite for backing up a statement? You might not need the particular one you’ve targeted. Similar work with results pointing to the same fact could be published elsewhere. This can happen because competing research groups often tend to publish parallel research at the same time, or else because findings are frequently reproduced by other labs to verify their integrity.

Sometimes a lab will publish figures analyzing the same data they had previously published in a new way, either in a review paper or in a subsequent research article where new, related data build over the old data. Alternatively, a review paper by another lab citing the paper you can’t access could cite the fact you seek substantially enough to serve as an adequate citation.

With any luck, you could find a source fitting any of these scenarios that is open access and can replace the citation you’d initially desired.

When it’s Time to Open Your Wallet

If none of the above options works, you may have to fork it over and pay the journal. Here are your options:

Purchase or Rent the Individual Paper

If it’s a particular paper that you can’t obtain for free and for which you just can’t find an open-access substitute, you may need to invest in access to that one paper. It may not be necessary to purchase it at the full price indicated by the paywall.

If the journal is published by a scientific society of which you are a member, the price is likely discounted for you. If the paper is from a Nature -branded journal, you could use ReadCube [20], which offers three different tiers of access:

• most cheaply, to rent the paper for 48 hours;
• intermediately, to purchase cloud access;
• and most expensively, to purchase the full PDF.

If this is a journal club article , you’ll need to purchase the PDF because you wouldn’t otherwise be able to print or share the paper with your group, just as you wouldn’t be able to import it into your reference manager. The lower tiers would still allow you to read the information from the paper for your use, and of course, you could always enter all the citation info into your reference manager.

Get a Personal Subscription

If you find yourself wishing you had access to different papers and a large proportion of them are from the same journal, it might be worthwhile to subscribe to that journal.

Perhaps you’re having a year during which you’re writing more than usual—the last year of your PhD, a period of grant-writing for a nonprofit startup that likely has few or no journal subscriptions of its own, or a year several years into a professorship at which point you’re hoping for tenure next quarter—and you might want to subscribe to a journal or two that particularly pertain to your work for that year (subscriptions are annual in most cases).

Admittedly, this is an expensive option, although personal, non-commercial subscriptions are usually priced lower than institutional ones. For instance, yearly individual subscriptions are $235 for PNAS [21], $835 for JLR [22] (though a subscription comes free of charge to members of ASBMB [23]), and $845 for Environmental Microbiology [24].

How to Find Free Articles on Google Scholar

There are tons of resources for students to find articles online, and Google Scholar is a top pick. Here's how to use it.

Are you working on a research project or simply looking for credible information? Google Scholar can help you find free and credible research articles.

Instead of searching for scholarly articles in a standard Google search, you can use a simpler method to find articles. Google Scholar is a division of Google that focuses on scholarly literature, that way you can easily find articles that you need for your research.

Find Free Articles on Google Scholar

You might enjoy reading insanely weird articles on Wikipedia . However, maybe it's time that you read information from the academics that the world has to offer.

It can be frustrating searching the internet for articles, without finding anything that doesn't require payment. Google Scholar offers a wide variety of research articles, many of which are available for free.

Here's how to find free articles on Google Scholar:

• Head to Google Scholar .
• Type out a keyword search in the search bar.
• When the results are displayed, only check for articles with a PDF text link.
• Click on the link for your desired article.
• Check if the article has a free downloadable link, or if you can read it for free online.
• Once you have found a free article, save the PDF document onto your device or read it online.

Typically, free articles on Google Scholar have a visible PDF text link next to the article title. If you are unlucky, the link will lead you to the publisher's website, where you would have to purchase the article.

However, when the article is free, you can save the document or read it online.

Finding Recently Published Articles

Google Scholar allows you to filter your search to a specific time frame. This way, you can find articles that were recently published, or that were published over 5 to 10 years ago.

To find an article according to the year it was published, click Since Year on Google Scholar's left sidebar. This allows you to find article papers that were published from the specified year. You can also choose whether you want the results page on Google Chrome to sort articles by date or relevance.

Click Sort by date to show just the new additions. If you are not too concerned about when the articles were published, you may click on Any time , which you will find in the left sidebar.

If you are looking for a less academic platform to gather information, you can use LinkedIn as a research tool  instead.

Improve Your Research Skills

Knowing how to research effectively is not an easy skill to have. Luckily, the internet makes life easier in so many ways. One of those ways is helping you research better.

If you are a research student, you might want to find out how to make the most of your search browser. That way you can get the best results from your research.

8 ways journalists can access academic research for free

A lot of academic research exists behind paywalls. We outline eight ways reporters can get free access to high-quality scholarship.

This <a target="_blank" href="https://journalistsresource.org/media/academic-research-free-journalists/">article</a> first appeared on <a target="_blank" href="https://journalistsresource.org">The Journalist's Resource</a> and is republished here under a Creative Commons license.<img src="https://journalistsresource.org/wp-content/uploads/2020/11/cropped-jr-favicon-150x150.png" style="width:1em;height:1em;margin-left:10px;">

This tip sheet outlining ways journalists can access academic research for free, originally published in September 2018, has been updated with new information.

Here at The Journalist’s Resource, we’re big fans of research — especially the peer-reviewed kind . We know academic research is one of journalism’s most valuable tools for covering public policy issues and fact-checking claims.

Unfortunately, journalists often have trouble accessing studies published in academic journals. Many journals keep scholars’ work behind paywalls, and subscriptions can be prohibitively expensive for newsrooms and individual journalists. For example, a subscription to the Proceedings of the National Academy of Sciences, a journal of the National Academy of Sciences, is more than $200 a year for one person for personal use only. There are thousands of journals worldwide.

Resourceful journalists find other ways to get that information. Here are eight of them:

Go to the library.

Public libraries often subscribe to academic journals and anyone with a library card can read them. The good news for busy journalists is some libraries allow their users to access online databases of peer-reviewed research from any location.

U.S. colleges and universities provide online access to academic journals through their academic libraries. State university libraries generally are open to the public. Private institutions often extend library privileges to alumni.

Ask academic journals for a free account.

Many of the most popular journals give journalists complimentary access, although some limit free accounts to journalists covering specific topics or beats. The American Economic Association (AEA), for instance, offers news media professionals free access to all eight of its journals, including the American Economic Review. You can request an account through the association’s press page .

“I don’t think it’s something that’s widely known, but it’s a message we want to get out there,” says Chris Fleisher, the AEA’s web editor. “We want journalists to know they can access our journals if they like.”

It’s worth noting that many journals will share embargoed copies of research articles with journalists and alert them to new research on a topic of interest. Contact the journals you’re interested in to learn more.

Search open access journals and platforms.

A growing number of scholarly journals known as open access, or OA, journals offer their online content for free to the public. Be aware that while there are many high quality OA publications, some engage in unethical practices. A trusted source of reputable OA journals is the Directory of Open Access Journals .

Examples of top OA journals include PLOS One , the world’s first multidisciplinary OA journal, and BMC Biology.

Several online platforms also allow the public to access research at no cost. One is Unpaywall.org, a free database of almost 48 million free-to-read academic articles.

Check Google Scholar.

Google Scholar is a web search engine that indexes research from various sources. Often, Google Scholar will provide PDF documents of research articles in its search results. However, some PDFs contain earlier versions of an article, including drafts that have not been peer reviewed or published.

While these earlier versions can be helpful, it’s important to contact the author before reporting on their findings. The findings highlighted in working papers are preliminary and may differ substantially from the final version published in a journal article. (To better understand the differences between a working paper and an academic article, check out our explainer .)

Install browser extensions. 

Browser extensions can help you check the web for free versions of academic articles. The Unpaywall browser extension gathers content from more than 50,000 journals and open-access repositories worldwide. The Open Access Button searches “millions of articles” from sources that include “all of the aggregated repositories in the world, hybrid articles, open access journals, and those on authors’ personal pages,” according to its website.

If the Open Access Button does not find free versions of the articles you’re looking for, it will contact the authors and ask them to share their work by putting it into an open access repository.

Reach out to the people who did the research.

If you find a research article you’re interested in reading but can only access the abstract online, call or e-mail the authors and ask for a complete copy. Journal abstracts generally include contact information for the authors or, at the very least, an e-mail address for the corresponding author.

Researchers usually will share copies of their work with journalists. If a scholar shares a pre-published version of an academic article, be sure to ask how closely it resembles the published version and whether the findings are the same.

Another option: Researchers often post links to their academic research on their personal websites. Those who work for colleges and universities tend to list their published articles on their faculty pages.

Call the media relations office.

The media relations office of a university or research organization can help you track down a copy of an article written by one of its researchers. It can help you reach the authors as well.

The main drawback: While media relations offices generally are sensitive to newsroom deadlines, they may be busy helping many journalists at the same time. It’s often faster and easier to reach out to authors directly. If you have trouble getting researchers to respond, media relations staff members are usually willing to give them a nudge.

Universities also send out press releases promoting new academic research conducted by their faculty and research centers. Ask how to receive alerts about topics key to your beat.

Sign up for newsletters and press releases from organizations that promote the scholarly work of various colleges, universities, research centers and other groups.

A quick way to get information about new research from a bunch of different research entities is by signing up for emails from organizations such as Futurity and EurekAlert!

Futurity is a partnership of 47 universities in the U.S., Canada, Europe, Asia and Australia. It highlights the work of scholars in four broad topic areas: culture, health, environment and science.

EurekAlert! is a news-release distribution platform run by the American Association for the Advancement of Science . It hosts news releases from higher education institutions, medical centers, government agencies, academic journal publishers, corporations and other groups involved in research across all fields.

If you’re looking for more help covering academic research, check out the “ Know Your Research ” section of our web site. We’ve created a series of tip sheets to help you get it right, whether you’re trying to make sense of key terms such as “ statistical significance ” and “ standard deviation ” or need guidance on spotting weaknesses in research and determining whether scholars have reached a scientific consensus on an issue.

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.

Harvard Library Is Launching Harvard Open Journals Program

Harvard Library is launching a new initiative called the Harvard Open Journals Program (HOJP), which will help researchers advance scholarly publishing that is open access, sustainable, and equitable. HOJP will provide publishing services, resources, and seed funding to participating Harvard researchers for new academic journals. All journal articles will be entirely free for authors and readers, with no barriers to publish or to access.

Martha Whitehead, Vice President for the Harvard Library and University Librarian, sees the initiative as an important step in championing open access. Whitehead said, “We want to model the original ethos of open access by reducing barriers and enabling the free flow of ideas and knowledge across the research ecosystem and beyond to the public at large.”

The Harvard Open Journals Program will offer publishing and hosting services to help the Harvard community launch new open access journals, or to convert existing journals to open access. The program will offer two support models: an overlay model which takes advantage of open access repositories, such as Harvard’s  DASH , and a brand-new academic press model. 

Yuan Li, University Scholarly Communication Officer and Director of Open Scholarship and Research Data Services at Harvard Library, pointed out the innovative nature of the program, “It is new for an institution to support faculty in seeking out an academic press to publish a no-fee open access journal and to provide assistance in securing its long-term funding. And offering a repository overlay journal model provides an alternative that appeals to some editorial boards and is gaining traction through initiatives such as Episciences. As we implement and refine this program on our campus, we hope it will inspire other universities to adopt such approaches to supporting barrier-free scholarly publishing.”

The program is a direct response to faculty interest in alternatives to the article-processing-charge model, in which journals charge author-side fees to publish papers open access. It also supports federal requirements that publications resulting from publicly-funded research be open access.

The open access movement in scholarly publishing seeks to grant free and public online access to publications and data. In recent decades, many researchers have become increasingly concerned that commercial rather than scholarly interests are driving the publishing ecosystem. With some publishers charging article processing fees of over $10,000 per article, skyrocketing costs inhibit many researchers and institutions from publishing in these journals. At the same time, research institutions continue to pay high subscription costs, even as their faculty provide editorial and peer review services mainly for free to the publishers. These practices have led to widespread outcry in the scholarly community, and tensions between publishers and editorial boards have led to the latter’s  mass resignations .

Scott Edwards, Professor of Organismic and Evolutionary Biology, and a member of the Harvard Library Faculty Advisory Council, applauds the library’s exploration of new models for supporting open access publishing. Edwards said, “In this increasingly challenging publishing ecosystem, the Harvard Open Journals Program is a welcome new approach.” 

“These are sustainable and equitable open access publishing models that allow scholars to take control of scholarly communication,” added Li. “I hope that many research-heavy institutions adopt our approach. The first  Harvard Open Access policy launched in 2008 has been adopted nationally and internationally, and it would be great to see similar reach.”

Under Harvard’s Open Access policies, Harvard faculty and researchers give the University a nonexclusive, irrevocable right to distribute their scholarly articles for any non-commercial purpose. Stored and preserved in  DASH , Harvard Library’s open access repository, these articles are made available to the scholarly community and the public—anyone with an internet connection can read them for free.

Harvard Library is working closely with the Office of the Vice Provost for Research on launching the HOJP program. John Shaw, Vice Provost for Research and Harry C. Dudley Professor of Structural and Economic Geology, is eager to promote the initiative in the suite of programs that support faculty research. Shaw said, “The launch of HOJP provides very encouraging options for removing barriers to making research results open and expanding their reach.”

The Harvard Open Journals Program will be open to all journals with a current Harvard affiliate on the editorial team or editorial board. Student-run journals are also eligible, as long as they are sponsored by a Harvard faculty member or administrator.

In preparing to launch HOJP this summer, Harvard Library is currently seeking input on program details from interested faculty. HOJP will begin accepting applications in the fall from journals and editorial boards. Colleen Cressman, Librarian for Open Publishing, will manage the program and can be reached by email for more information.

How to get out of the debt trap? Navigating the global financial turmoil

Global economies faced a precarious cycle of recovery pre-pandemic, marked by currency imbalances and interest rate cuts, resulting in a staggering 300 trillion USD global debt burden. Urgent reform of the international monetary system is necessary to address escalating geopolitical crises and economic vulnerabilities, requiring coordinated efforts and a shift towards inclusive and resilient frameworks. Renowned French experts Jean-François Serval, president of Groupe Audit Serval & Associés, and Jean-Pascal Tranié, founder and president of Aloe Private Equity, propose transforming stagnant financial reserves into wealth by converting a sizeable portion of public debt into productive assets within the real economy.

Amidst the backdrop of financial tumult, preceding both the COVID-19 pandemic and the Russia-Ukraine war, global economies experienced a precarious cycle of recovery. However, this resurgence, culminating in 2018, relied heavily on currency imbalances and interest rate cuts, fostering a colossal global debt burden. This debt – now nearing 300 trillion USD including over 100 trillion in public debt, or almost 120% of global GDP – presents a formidable challenge due to its complexity and escalating magnitude. The disparity between this debt and the stagnant GDP in Western countries underscores a systemic distortion, fostering distrust in the monetary system and fuelling volatility in financial markets.

The root of this systemic malaise can be traced back to the post-World War II era, characterised by the dominance of the US dollar and from the 1980s onwards, after three decades of strong growth, subsequent lack of rapid inflation to offset nominal debts. As economic actors increasingly decouple monetary volumes from currency, the debt spiral intensifies, facilitated by artificially low interest rates and state guarantees. This relentless debt expansion, exacerbated by a revolution in payment methods, poses an existential threat to the global economy.

In response to the escalating geopolitical crisis and mounting economic vulnerabilities, urgent reform of the international monetary system is imperative. The onset of conflict amplifies inflationary pressures and increases public debt burdens, necessitating a coordinated effort to redefine global economic governance.

Despite escalating tensions and geopolitical rivalries, a negotiated transition to a more inclusive and resilient monetary framework is not only feasible but essential for global stability. Europe, as a significant economic player, stands poised to facilitate dialogue and cooperation between competing powers, underscoring the need for a multipolar monetary conference to recalibrate the global economic order.

The book Financial Innovations and Monetary Reform: How to Get Out of the Debt Trap offers a groundbreaking perspective on global monetary reform. Authored by renowned French experts Jean-François Serval, president of Groupe Audit Serval & Associés, and Jean-Pascal Tranié, founder and president of Aloe Private Equity, a regulated fund management company, the daring vision presented advocates for the conversion of public debt into equity in productive businesses, fostering innovation and economic growth.

With a focus on technical feasibility, the authors aim to galvanise support for their bold approach which aligns with ongoing efforts to invest in vital infrastructure and pioneering research projects worldwide – projects that are profitable because they help develop trade. As proponents of a new era in economic policy, their work underscores the urgent need for innovative solutions to navigate the complexities of global debt.

Restructuring public debt: The core of monetary reform

The authors propose that, to navigate the current economic imbalance, characterised by skewed risk-reward dynamics and, until recently, effectively negative rates, a fundamental shift is imperative. This entails reducing public debt to restore a market-driven system of capital remuneration, devoid of state intervention. By aligning bond and share dividends with market risk appreciation, governments can facilitate a significant reduction in the public debt burden.

However, addressing this challenge requires careful consideration of potential avenues for debt adjustment. Options range from central banks raising long-term rates to promote debt repayment, to exploring debt conversion into non-repayable equity instruments, as proposed by the authors. Each approach carries distinct implications for economic stability and market dynamics, underscoring the complexity of the task at hand.

Rocking the boat: Stirring up value reduction with rate hikes

Serval and Tranié highlight that before the pandemic, central banks contemplated elevating interest rates to counter the rising tide of public debt – a move that would ripple through financial markets. Investors wary of government debt sought refuge in tangible assets like real estate and corporate securities, diminishing the appeal of purely financial securities. However, a rate hike would precipitate a market downturn, prompting a mass exodus of investors.

Governments have been reluctant to raise rates, fearing repercussions on investment and consumption. While the Federal Reserve initiated rate hikes, the European Central Bank’s (ECB) cautious approach underscores the diverse economic landscape within the eurozone. However, recent announcements signal a shift in policy, with the ECB opting to cease securities purchases and initiate rate hikes, signalling a growing consensus on the need for debt reduction and macroeconomic stability.

The debt dilemma

Debts, often viewed one-dimensionally, represent only the flip side of claims within interconnected economic entities. While they optimise cash flow and facilitate market debt, debts themselves don’t alter economic realities. Through a process of offsetting balances within a group of interconnected companies, debts can decrease without impacting the real economy.

This process, typical in financial and industrial groups, offers clarity on debt amounts without altering economic exchanges. However, it doesn’t affect individual debts to companies or total public debt. While it highlights quantity of debts, this method doesn’t address the structural necessity of reducing debt as a critical facet of monetary reform.

Exploring equity

The authors propose that the path to reducing public debt lies in converting it into equity, tailored to the unique circumstances of each currency zone. Governments and monetary authorities, as last resorts, must address false money that has been issued to avoid default, which would harm all savers and pensioners. Most debt holders, primarily financial institutions, find these debts difficult to access before maturity.

A zone-by-zone debt reduction strategy, utilising funds financed by central bank issues, offers a solution. These funds would buy back existing assets or create new ones, exchanging them for debts held by institutions. This process, while issuing new money, wouldn’t impact the real economy, as this conversion would relate to future commitments, essentially retirement pensions, which do not interrupt immediate payments. However, the transition necessitates careful consideration of voting power transfers and the concession of public assets to the private sector. Ultimately, this approach safeguards against interest rate manipulations and proposes a coordinated international effort to stabilise debt reduction and increase interest rates gradually.

Debt reduction

The authors’ approach to addressing overwhelming debt isn’t about simply brushing it off or staggering payments indefinitely. Instead, they aim to breathe life into deflationary financial masses by transforming them into tangible wealth creation. To achieve this, they propose a substantial portion of public debt be converted into equity within companies, fostering new profitable investment ventures. This involves exchanging low or negative-rate public securities for products with progressive rates, ensuring better long-term profitability for holders.

While most public debts can be cleared within economic zones, reserve currencies, the dollar for the essentials, present a unique challenge due to their extensive international use. To ensure the overall coherence of the monetary system, the researchers’ plan provides a decentralised debt transformation, facilitated by structures like hive-off funds, which manage investments while ensuring liquidity to honour debt commitments, particularly for pension systems transitioning to funded models. Three major economic zones can be identified: the eurozone, the dollar zone, and Asia, which can be divided into two main zones: the Chinese world and its periphery, which includes Japan and Korea, and India.

To prevent disruption, equity instruments replacing debt may lack voting rights, unless companies seek to internationalise with the arrival of new shareholders. A debt-for-equity swap, restoring confidence in balance sheets, promises economic growth, bolstering stock markets and facilitating a more balanced interest rate scale for investments. Gradual implementation, controlled by international agreements, is crucial to avoid destabilising money supplies.

Forging a new financial frontier

The world is grappling with excessive money supply and a lack of international financial regulation, leading to soaring public debt. Serval and Tranié’s proposal aims to transform this debt into tangible wealth creation, rather than perpetually deferring payments. Converting public debt into equity in companies and investing in profitable projects will help alleviate the burden of debt while stimulating economic growth.

However, this approach requires coordinated action within major economic zones and careful consideration of international implications. The current reliance, implemented over the last years, on low or negative interest rates to sustain public debt is unsustainable and poses risks of inflation and financial instability. Instead, a fundamental reform reducing public debt and promoting productive investments is necessary.

The ongoing initiatives like China’s Belt and Road Initiative and proposed digital currency standards signal a shift towards a new international financial order. This reform must complement prudent financial mechanisms to prevent systemic failures and ensure sustainable economic growth. Ultimately, addressing the challenges of public debt and monetary reform requires concerted efforts on a global scale, acknowledging the geopolitical dimensions and adapting to the realities of the contemporary world.

Despite a fortified border, migrants will keep coming, analysts agree. Here's why.

Sergio Martínez-Beltrán

Border Patrol picks up a group of people seeking asylum from an aid camp near Sasabe, Arizona, on Wednesday, March 13, 2024.

The U.S. southern border is as fortified as ever and Texas is carrying out its own enforcement to stop people from crossing illegally, yet observers and analysts agree on this: migrants not only will continue to come, but their numbers will likely increase in the coming months.

The expected surge can be attributed not only to seasonal migration patterns, but an increase of people displaced by war, poverty, and climate factors in all continents.

And why do these analysts say this?

They keep a close eye on the Darién Gap in Panama and the borders between Central American countries, two key points to gauge the number of people venturing up north.

"In most countries (outward) migration has increased ... particularly in Venezuela, and that's not really reflected yet in the U.S. numbers," said Adam Isacson, an analyst of border and migration patterns at the Washington Office on Latin America, a nonpartisan research and advocacy organization based in Washington D.C.

Despite Mexico's cracking down on migrants, Isacson said people are still making their way up north, even if they need to pause for months at different points during their journey.

"There must be a huge number of people from Venezuela bottled up in Mexico right now," he said.

The Darién Gap serves as a good barometer for migration flows.

This 100-mile-long tropical jungle between Colombia and Panama has claimed the lives of hundreds of migrants, according to a report from the Migration Policy Institute, a Washington, D.C.-based think tank.

Yet the dangers at this jungle are not a deterrent, said Ariel Ruiz Soto, a senior policy analyst with this organization. The majority of people migrating are from Venezuela.

"The reason why I referred to Venezuelans in particular is because they represent a key challenge for removals from Mexico and from the United States to Venezuela," Ruiz Soto said.

Mexico and the U.S. had been flying Venezuelan migrants back to the South American country . However, earlier this year, Venezuelan President Nicolás Maduro stopped accepting flights from the U.S. in response to economic sanctions imposed by the Biden administration.

Panama reported a 2% increase in crossings through the Darién Gap in February compared to the previous month.

What the numbers show

Analysts are projecting the increase in the remaining months of the fiscal year, even though U.S. Customs and Border Protection reported a 2.2% decrease in encounters with migrants along the Southern border in March. An encounter is every time a migrant is picked up by immigration authorities.

These numbers are consistent with cyclical patterns of illegal crossings that dip in the winter months, followed by more migrants attempting to get to the U.S. as warm weather arrives, said Ruiz Soto.

In a statement, CBP Spokesperson Erin Waters said the agency remains vigilant to "continually shifting migration patterns" amid "historic global migration."

Waters said the agency has also been partnering with Mexico to curb the flow of people migrating to the U.S.

Mexico has commissioned its National Guard to patrol its borders with Guatemala and the U.S.

"CBP continues to work with our partners throughout the hemisphere, including the Government of Mexico, and around the world to disrupt the criminal networks who take advantage of and profit from vulnerable migrants," Waters said.

Where are migrants crossing the border?

For the last few months, more migrants are attempting to cross through Arizona instead of Texas, according to CBP.

In 2023, the El Paso and Del Rio sector in Texas saw more crossings than any other place across the 2,000-mile Southern border. But this year the Tucson sector in Arizona has seen a 167% increase in crossings, more than any other.

Tiffany Burrow, operations director at Val Verde Border Humanitarian Coalition, an assistance organization for newly border crossers in Del Rio, said she has seen the shift.

"It's empty," Burrow said, pointing to her organizations' office. "There are no migrants."

In March, she helped only three migrants after they were released by CBP pending their court date. In December, they helped 13,511 migrants.

Burrow said that's how migration works — it ebbs and flows.

"We have to be ready to adapt," Burrow said.

Texas' role

Burrow and other immigrant advocates are closely observing Texas' ramping up of border enforcement.

In 2021 Gov. Greg Abbott launched Operation Lone Star initiative and deployed the Texas National Guard. Last year the state started lining up razor wire in sections of the Rio Grande.

Texas is also asking the courts to be allowed to implement a law passed last year by the Republican-controlled legislature, known as SB4, which requires local and state police to arrest migrants they suspect are in the country illegally.

It might be too early to know if all these efforts will have an impact on migration patterns, analysts said, considering that Texas saw the highest number of illegal crossings last year.

But, Mike Banks, special advisor on border matters to Abbott, said the state's efforts are fruitful.

Texas has spent over $11 billion in this initiative.

"The vast majority of the United States' southern border is in Texas, and because of Texas' efforts to secure the border, more migrants are moving west to illegally cross the border into other states," said Mike Banks in a statement to NPR.

Ruiz Soto, from the Migrant Policy Institute, said the impact of Texas' policies on arrivals "is likely to be minimal over the long term."

Carla Angulo-Pasel, an assistant professor who specializes in border studies and international migration at the University of Texas at Rio Grande Valley, said that even with Texas' policies in place, migrants are likely to continue to cross.

"You can't claim, as much as I think Gov. Abbott wants to claim, that Operation Lone Star is going to somehow mean that you're going to see less numbers in Texas because that hasn't held true," Angulo-Pasel said. "We could also argue that things are going to progressively get more and more as the spring months progress."

How cleaning product chemicals called ‘quats’ may affect the brain

A common ingredient in household disinfectants has been shown in lab studies to affect certain brain cells.

The pandemic ushered in a cleaning frenzy at home, schools and work as many of us sprayed, wiped and disinfected our way through the crisis.

But widespread use of disinfectants and heavy-duty cleaners has also ushered in new research on “quats” — which stands for quaternary ammonium compounds (sometimes called QACs). Quats are a class of chemicals used in some household cleaners that kill viruses, bacteria and other germs by breaking down cell membranes.

In a 2023 review , more than two dozen researchers called quats “a chemical class of emerging concern.” Exposure to quats has been associated with asthma and an increased risk of chronic obstructive pulmonary disease in humans, as well as decreased fertility in mice .

Now, scientists at Case Western Reserve University School of Medicine in Cleveland have raised a new concern: They’ve found quaternary ammonium compounds to be potentially toxic to a type of brain cell. These cells, called oligodendrocytes, provide the fatty insulation (called myelin) around nerves, which allows neural signals to travel through the brain faster. The study also found that organophosphate flame retardants used in some household furniture appear to stunt the growth of oligodendrocytes.

“We’re not looking to say that there’s a direct correlation between exposure and human neurodevelopmental issues. We don’t have that data yet,” said Paul Tesar , the director of the Institute for Glial Sciences at Case Western Reserve and the principal investigator of the study. “But we have fundamentally shown, very rigorously, that oligodendrocytes have a specific vulnerability to these chemicals.”

There are hundreds of quaternary ammonium compounds, which can make it hard to identify the chemicals on an ingredient list. Quats often end with “ammonium chloride” or “onium chloride” in the name. One common quaternary ammonium compound in hand soaps, for instance, is benzalkonium chloride. Google can also help you figure out whether a particular ingredient in a cleaning product is a quaternary ammonium compound.

The American Cleaning Institute , a trade association for cleaning product makers, downplayed the findings. Brian Sansoni, senior vice president of communications, wrote in an email that the study “does not establish a causal link to any known or observed human health effect and should not be interpreted by readers to be predictive of possible health effects.”

“Surface disinfecting products, including those with quaternary ammonium compounds, are highly regulated and extensively evaluated for safety according to their approved uses,” Sansoni wrote. “Quats are a critical public health solution across homes, schools, health care settings and communities every single day. ”

What to know about brain health and quats

The research on quaternary ammonium compounds doesn’t mean we should stop disinfecting our homes, experts say. But it’s good to be aware of the chemicals in your household cleaners, and to make informed decisions about which products you choose.

Erin Cohn, a graduate student in Tesar’s lab and the lead author of the study, said oligodendrocyte dysfunction is linked to various neurological conditions. In cases of multiple sclerosis, for instance, the body’s immune system attacks the insulation created by oligodendrocytes.

To study quats, the researchers used stem cells to grow human brain organoids — petri dishes of tiny, “millimeter-sized brain tissue” — intended to mimic early stages of brain development, Tesar said. And they found the quaternary ammonium compounds specifically killed oligodendrocytes but not the other cell types.

The researchers also fed the chemicals to young mice for 10 days. In autopsies, they found exposure to quats had “caused a selective loss of oligodendrocytes” in the brain, Tesar said.

“The science is clear that these chemicals have harmful effects on oligodendrocytes,” Tesar said. What’s not clear is whether “everyday exposure” to these chemicals affects the human brain.

Francisco Javier Quintana , a professor of neurology at Harvard University, said the brain is influenced “all the time” by the chemicals a person takes in. Although more study is needed, the results of the latest research suggest that exposure to quats could trigger disease in certain populations that are already genetically susceptible, he said.

“The quats could be acting as one little push, or the final push across the finish line,” Quintana said. “In most people, quat exposure probably does nothing. But if you carry the wrong genetic background, that might trigger disease development.”

What’s our exposure to quats?

Quaternary ammonium compounds have been detected in the breast milk of mothers, and they were higher in women who used disinfecting cleaning products. And a study of 43 people found that 80 percent had quats in their blood.

Libin Xu , an associate professor of medicinal chemistry at the University of Washington, said exposure to quats is “ubiquitous.” Almost every sample measured so far “has certain amounts of this compound, from very low to, occasionally, pretty high amounts,” he said.

In New York, researchers looked at quat exposure in shelter dogs, who live in caged areas that are frequently cleaned and disinfected. The study found that the feces of shelter dogs contained from two- to 18-fold higher concentrations of certain quats, compared with those of dogs who lived with their owners.

Terry Hrubec , a professor of anatomy and embryology at the Edward Via College of Osteopathic Medicine in Blacksburg, Va., said that, although we know quats can get into the body, “we know almost nothing” about their effects. “We’re just scratching the tip of the iceberg for what we know about quats,” Hrubec said.

Cleaning with soap and water

Not all household disinfectants use quaternary ammonium compounds, and there are alternatives “that are equally effective,” with ingredients such as citric acid, ethanol and hydrogen peroxide, said Sarah Evans , an assistant professor of environmental medicine and climate science at the Icahn School of Medicine at Mount Sinai in New York.

If you’re concerned about the active ingredients in a disinfectant you’re using, open a window, and don’t spray or wipe with the product around children or pregnant people, Evans said. “Regular soap and water will kill most bacteria,” Evans said. “You don’t need a soap that has an added antibacterial chemical.”

Martin Wolf, director of sustainability for Seventh Generation, a maker of detergents and other cleaning products, said in an email that the company doesn’t use quats in its disinfecting products. The chemicals “have long been associated with respiratory irritation,” Wolf said.

Wolf said that, because the study was conducted on cultured cells in a lab, it’s not clear how it applies to the real-world use of cleaning products that contain quats. “It would be improper to dismiss the study out-of-hand,” Wolf said. “Rather, this should be seen as a caution to avoid use of the substances studied and to seek alternatives.”
