Share All sharing options for: The war to free science

The 27,500 scientists who work for the University of California generate 10 percent of all the academic research papers published in the United States.

Their university recently put them in a strange position: Starting July 10, these scientists will not be able to directly access much of the world’s published research they’re not involved in.

That’s because in February , the UC system — one of the country’s largest academic institutions, encompassing Berkeley, Los Angeles, Davis, and several other campuses — dropped its nearly $11 million annual subscription to Elsevier, the world’s largest publisher of academic journals.

On the face of it, this seemed like an odd move. Why cut off students and researchers from academic research?

In fact, it was a principled stance that may herald a revolution in the way science is shared around the world.

The University of California decided it doesn’t want scientific knowledge locked behind paywalls, and thinks the cost of academic publishing has gotten out of control.

Elsevier owns around 3,000 academic journals, and its articles account for some 18 percent of all the world’s research output. “They’re a monopolist, and they act like a monopolist,” says Jeffrey MacKie-Mason , head of the campus libraries at UC Berkeley and co-chair of the team that negotiated with the publisher. Elsevier makes huge profits on its journals , generating billions of dollars a year for its parent company RELX.

This is a story about more than subscription fees. It’s about how a private industry has come to dominate the institutions of science, and how librarians, academics, and even pirates are trying to regain control.

The University of California is not the only institution fighting back. “There are thousands of Davids in this story,” says the head of campus libraries at the University of California Davis MacKenzie Smith, who, like other librarians around the world, has been pushing for more open access to science. “But only a few big Goliaths.”

Will the Davids prevail?

The academic publishing industry, explained

Imagine your tax dollars have gone to build a new road in your neighborhood.

Now imagine that the company overseeing the road work charged its workers a fee rather than paying them a salary.

The overseers in charge of making sure the road was up to standard also weren’t paid. And if you, the taxpayer, want to access the road today, you need to buy a seven-figure annual subscription or pay high fees for one-off trips.

We’re not talking about roads — this is the state of scientific research, and how it’s distributed today through academic publishing.

Indeed, the industry built to publish and disseminate scientific articles — companies such as Elsevier and Springer Nature — has managed to become incredibly profitable by getting a lot of taxpayer-funded, highly skilled labor for free and affixing a premium price tag to its goods.

Academics are not paid for their article contributions to journals. They often have to pay fees to submit articles to journals and to publish. Peer reviewers, the overseers tasked with making sure the science published in the journals is up to standard, typically aren’t paid either.

And there’s more: Academic institutions have to purchase exorbitant subscriptions priced at hundreds of thousands of dollars each year so they can download and read their own and other scientists’ work from beyond the paywall. The same goes for members of the public who want to access the science they’ve funded with their tax dollars. A single research paper in Science can set you back $30 . Elsevier’s journals can cost, individually, thousands of dollars a year for a subscription .

Publishers and journal editors say there are steep costs associated with digital publishing, and that they add value at every step: They oversee and manage peer reviewers and editors, act as quality gatekeepers, and publish an ever-larger number of articles each year.

We spoke with executives at both Elsevier and Springer Nature, and they maintain their companies still provide a lot of value in ensuring the quality of academic research. It’s true these companies are not predatory journals , businesses that will publish just about any paper — without any scientific vetting — for a fee.

In 2018, Elsevier’s revenue grew by 2 percent , to a total of $3.2 billion. Gemma Hersh, a senior vice president for global policy at Elsevier, says the company’s net profit margin was 19 percent (more than double the net profit of Netflix ).

But critics, including open access crusaders, think the business model is due for a change. “I think we’re nearing the tipping point, and the industry is going to change, just like the industry for recorded music has changed, the industry for movies has changed,” MacKie-Mason says. “[The publishers] know it’s going to happen. They just want to protect their profits and their business model as long as they can.”

It’s a business model as convoluted as the road you paid for but can’t use. And it grows more expensive for universities every year.

Now the status quo is slowly shifting. There is a small army of people who aren’t putting up with the gouging any longer.

This disparate band of revolutionaries is waging war on the scientific publishing industrial complex on three fronts:

• Librarians and science funders are playing hardball to negotiate lower subscription fees to scientific journals.
• Scientists, increasingly, are realizing they don’t need paywalled academic journals to act as gatekeepers anymore. They’re finding clever workarounds, making the services that journals provide free.
• Open access crusaders, including science pirates, have created alternatives that free up journal articles and pressure publishers to expand access.

If they succeed, the cloistered, paywalled way that science has been disseminated for the past century could undergo a massive transformation. The walls, in other words, could fall.

If paywalls fall, the impact would reverberate globally. When science is locked behind paywalls, it means cancer patients can’t easily access and read the research on their conditions (even though research is often taxpayer-funded). When scholars can’t read the latest research, “that hinders the research they can do, and slows down the progress of humanity,” MacKie-Mason says.

But there’s a big thing getting in the way of a revolution: prestige-obsessed scientists who continue to publish in closed-access journals. They’re like the road workers who keep paying fees to build infrastructure they can’t freely access. Until that changes, the walls will remain firmly intact.

How academic journals became so unaffordable

Scientific journals, published mainly by small scientific societies, sprouted up alongside the printing industry in the 17th century as a way to disseminate science and information about scientific meetings.

The first scientific journals, the Journal des sçavans and the Philosophical Transactions of the Royal Society of London , were distributed via mail. Like all pre-internet publishing models, early journals sold subscriptions. It wasn’t the hugely profitable industry it is today.

After World War II, the business changed dramatically. The journals — which were mostly based in Europe — focused on selling subscriptions internationally, targeting American universities flush with Cold-War era research funding. “They realized you can charge a library a lot more than an individual scholar,” says Aileen Fyfe , a historian specializing in academic publishing at the University of St. Andrews.

As more and more journals popped up, publishing companies began consolidating. In the 1950s, major publishers started to purchase journals, transforming a once diffuse business into what’s been called an oligopoly : a market controlled by a tiny number of producers.

By the early 1970s, just five companies — Reed-Elsevier, Wiley-Blackwell, Springer, and Taylor & Francis — published one-fifth of all natural and medical scientific articles, according to an analysis in PLOS One . By 2013, their share rose to 53 percent.

No single publisher embodies the consolidation, and the increase of costs, more than Elsevier, the biggest and most powerful scientific publisher in the world. The Dutch company now publishes nearly half a million articles in its 3,000 journals, including the influential Cell , Current Biology , and The Lancet .

And the consolidation, the lack of competition, means publishers can get away with charging very high prices.

When the internet arrived, electronic PDFs became the main medium through which articles were disseminated. At that point, “librarians were optimistic this was going to be the solution; at last, journals are going to become much, much cheaper,” Fyfe says.

But instead of adopting a new business and pricing model to match the new means of no-cost dissemination, consolidation gave academic publishers the freedom to raise prices. Starting in the late 1990s, publishers increasingly pushed sales of their subscriptions into large bundled deals. In this model, universities pay a hefty price to get a huge subset of a publisher’s journals, instead of purchasing individual titles.

The publishers argue the new mode of digital delivery has come with an array of additional costs. “We’re continuing to invest significantly in digital infrastructure, which has a lot of fixed costs that repeat each year. We’re employing thousands of technologists,” said Elsevier’s Gemma Hersh. “So it’s not the case that digital is cheaper.”

The publishers also say that the volume of articles they publish every year increases costs, and that libraries ought to be funded to pay for them. “The libraries are treated by the senior academics at these institutions as a fixed cost; they’re not a fixed cost,” says Steven Inchcoombe, the chief publishing officer at Springer Nature, which publishes the prestigious Nature family of journals.

In a July 10 statement , Hersh said of Elsevier’s battle with the UC system “this stalemate was avoidable” and that the company hopes “we can find a pragmatic way forward if there is will and engagement from both sides.”

The librarians beg to differ. For universities, the most frustrating development is that cost of access keeps rising at a very steep rate.

Take a look at this graph from the Association of Research Libraries. It shows the percent change in spending at university libraries. The category “ongoing resources expenditures” includes spending on academic journals, and it rose 521 percent between 1986 and 2014. Over that time, the consumer price index — the average increase of costs of common household goods — rose 118 percent.

Librarians at the breaking point

The University of Virginia has a website where you can see how much money its library is spending on journals. From 2016 to 2018, the costs for Elsevier journals increased by $118,000 for the university, from $1.716 million a year to $1.834 million.

The data shows that the university is also spending a lot of money for journals that no one who uses their library system reads. In 2018, the university paid Springer Nature $672,000 for nearly 4,000 journals — 1,400 of which no one ever accessed. No one at UVA read the Moscow University Chemistry Bulletin , or Lithology and Mineral Resources , for example.

Why are universities paying for journals that no one reads? “It’s a lot like the cable bundle — they tell you you’re getting 250 channels, but if you look inside your heart, you know all you want is ESPN and AMC,” says Brandon Butler , director of information policy at the University of Virginia Library. An individual journal subscription can cost a university thousands of dollars. “UVA is absolutely considering cutting these bundles,” he says. “It’s quite likely we will, unless the price and other terms change radically.”

As the University of North Carolina Chapel Hill librarian, Elaine Westbrooks is facing what she and so many other academic librarians call the “serials crisis”: “If we buy the exact same journals every year, I have to pay at least $500,000 more just for inflation,” she says. “I can’t afford it.”

In her ongoing negotiations with Elsevier, Westbrooks is considering “the nuclear option,” as she puts it. That is, canceling the subscription that gives UNC Chapel Hill students and faculty access to thousands of Elsevier journals.

“It felt very much in 2017 the librarians felt beaten by the system and they couldn’t afford it,” says David Stuart, the researcher behind a yearly survey on the academic publishing industry. “Whereas in 2018, you could feel there was a bit more strength and power emerging, and they had the ability to push back on the publishers a bit.”

Science funders increasingly are calling for open access

It’s not only librarians waking up to the fact that the costs of accessing science are unsustainable — so are science funders. A lot of the money that fuels this system comes from government grants. In the US, taxpayers spend $140 billion every year supporting research, a huge percentage of which they cannot access for free. When scientists do want to make their work open access (meaning published without a paywall), they’re charged an extra fee for that as well.

This year, a consortium of public research institutions in Norway canceled its Elsevier contract, a move that followed a research consortium in Hungary breaking ties with the Dutch giant. In Germany , nearly 700 libraries and research institutes made a deal with the publisher Wiley: For about 25 million euros, they’re paying to access journal content — but also demanding the work of their researchers, published in Wiley journals, be made open access for all at no additional cost.

These institutions and funders are also banding together as part of Coalition S : The agreement says all scientific publications that have sprung from publicly funded research grants must be published on open access journals or platforms by 2020.

“The ambition is if the University of California does this deal, Germany does this deal — we eventually get to the point where [all science is] open access. The libraries are no longer paying to subscribe, they’re paying to publish,” said Robert Kiley, the head of open research at the UK’s Wellcome Trust.

But open access doesn’t necessarily mean cheap. Currently, publishers typically charge academics to publish that way too. If you want your article to be open access in an Elsevier journal, you could pay anywhere from $500 — the fee to publish in Chemical Data Collections — up to $5,000, the fee to publish in European Urology.

“Open access is absolutely in the best interest of the research process,” Inchcoombe, the chief publishing officer at Springer Nature, says. “If you can pay once and then it’s free for everybody, you eliminate a lot of the friction from the system of access and entitlement.” He hopes publishing will transition, over time, to open access.

But he stresses that open access won’t change “the fact that if you do more research, and you want to communicate it to more people, then there is a cost of doing that that rises with volume.”

Put another way: Publishers are still going to get paid. Open access just means the paychecks come at the front end.

This brings us to another band of revolutionaries in the fight against the status quo: the scientists who want to find ways to circumvent the behemoth publishers.

Some scientists are saying no to the big publishers and spinning off open access journals of their own

The structure of academic publishing isn’t just a pain for librarians and funders; it’s a bad deal for academics too. Basically, scientists trade in their hard work, their results for their toils in the lab, for free, to a private industry that makes tons of money off their work, in return for prestige.

Some researchers have been waking up to this and spinning off freely accessible journals of their own. One of those scholars is a University of Cambridge mathematician named Timothy Gowers . In 2012, he wrote a post bemoaning the exorbitant prices that journals charge for access to research and vowed to stop sending his papers to any journal from Elsevier .

To his surprise, the post went viral — and spurred a boycott of Elsevier by researchers around the world. Within days , hundreds of researchers left comments commiserating with Gowers, a winner of the prestigious Fields Medal. Encouraged by that response, in 2016, Gowers launched a new online mathematics journal called Discrete Analysis . The nonprofit venture is owned and published by a team of scholars. With no publisher middlemen, access is completely free for all.

University of Montreal professor and open access researcher Vincent Larivière has helped take the Elsevier boycott another step further. In January 2019, the entire editorial board of the Elsevier-owned Journal of Informetrics (including Larivière) resigned , and moved to MIT Press to start another open access journal, Quantitative Science Studies .

Again, the move was a principled one. “There’s a universalistic aspect to science, where you want it to be available to everyone,” Larivière said.

Even in the absence of starting open access journals, though, some scientists have been taking quieter, but equally principled, stands. One paleontologist took his name off a paper because his co-authors wouldn’t publish in an open access journal.

One key reason scientists, librarians, and funders can fight back is because other crusaders have made research more accessible. Enter the pirates.

Pirating and preprints are also pressuring the publishing industry to increase access

Over the past decade, it’s been getting easier and easier to circumvent the paywalls and find free research online. One big reason: pirates, including Kazakh neuroscientist Alexandra Elbakyan. Her (illegal) website Sci-Hub sees more than 500,000 visitors daily, and hosts more than 50 million academic papers.

But Sci-Hub is just one tool to get around paywalls. Scientists are also increasingly publishing prepublication versions of their studies (often called preprints). These study drafts are free to access.

The problem is that often, these studies have not yet been peer-reviewed. But advocates of preprints say they’re a net benefit to science: They allow for the public discussion of papers before they’re set in a finalized form — a type of peer review. And there are more preprints than ever before. (Some of the preprint servers are owned by the big publishers too.)

To find these preprints, all it takes is a single click: Unpaywall , a browser extension, helps users find the preprints associated with paywalled journal articles.

These mounting pressures on the academic publishing industry aren’t so different from the pressures on the music industry in the late ’90s. If you recall, in the late ’90s, music pirating was suddenly everywhere. You could log in to Napster and Limewire and illegally download any song you wanted for free.

“Piracy seems to come in when there’s a market failure,” UVA’s Butler says, “and people aren’t getting what they need at a price that makes sense for them.”

But as Larivière points out, Sci-Hub isn’t a long-term solution, and eventually, it may not even be needed: “Once there’s no paywalls, there’s no Sci-Hub anymore.”

What’s standing in the way of a full-on revolution? The culture of science.

For now, the paywalls mostly stand. Elsevier’s profits have actually increased in recent years. And as Elsevier’s Hersh told us, while the volume of open access research published by the company has been growing, so has the volume of paywalled papers.

Even with the growing pressure from the open science crusaders, the publishers remain in an extremely strong and nimble position. More and more, Elsevier’s business is not in the publication of journal articles, but in data-mining its enormous library. That means it’s using analytics to report on research trends, recommend articles scientists ought to be reading, and suggest co-authors to collaborate with based on shared interests.

Even if the publishers lose ground on selling subscriptions, they’ll still offer a profitable service based on control of the content. Still, it’s not hard to imagine a future where more and more institutions of science simply ignore, or circumvent, the major publishers.

The growing popularity of preprints is giving them one avenue to escape. One could imagine a system where researchers upload their drafts to preprint servers and then other academics choose to peer-review the articles. After peer review and revision, that preprint paper could be given a stamp of approval and added to a digital journal. This system is called an overlay journal (in that the editing and journal gatekeeping is overlain on top of preprints), and it already exists to a small extent . (Gowers’s Discrete Analysis is an overlay journal.)

So it’s not technology or innovation holding science back from a revolution. “The biggest elephant in the room is how researchers are rewarded for the work they do,” said Theodora Bloom , the executive editor at BMJ .

At the moment, researchers’ careers — the grants they’re given, the promotions they attain — rise or fall based on the number of publications they have in high-profile (or high-impact) journals.

“If an academic has a paper in Nature or Science, that’s seen as their passport to their next grant or promotion,” said Bloom.

As long as those incentives exist, and scientists continue to accept that status quo, open access journals won’t be able to compete. In fact, many academics still don’t publish in open access journals . One big reason: Some feel they’re less prestigious and lower quality , and that they push the publishing costs on the scientists.

“I’m also waiting to see change within academic culture,” says Fyfe, the historian. “Until we have enough academics who are willing to do something different, then I don’t see a big change happening.”

So for now, the revolution is just beginning. “Everyone agrees, in some way, the future is open access,” UVA’s Butler says. “Now the question is, in that future, how much control do the big publishers retain over every step in the scientific process? They’ve been working for over a decade to ensure the answer is the most possible control.”

Academic publishing isn’t a hot-button political topic. But it could be. “If citizens really cared, they could talk to their representatives and senators and tell them open access matters,” MacKie-Mason says, “and the government should get involved in changing this.“

How to get past paywalls and read scientific studies

No need to fly the Jolly Roger, either.

By Whitson Gordon | Published Oct 23, 2019 9:37 PM EDT

Popular Science stories often link directly to scientific studies. You can get all the information you need from the articles themselves, and even more from these links, but if you get the urge to investigate further—perhaps to see the data for yourself—you’ll want to read the study firsthand. Unfortunately, many academic papers are hidden behind expensive paywalls.

There’s a lot to say about the academic research industry, but many believe scientific studies should be freely available to the public . Even if you find a paper that’s hidden behind a paid subscription, there are ways to get it for free—and we’re not talking about piracy. Often, the study you’re looking for may be freely, legally available elsewhere, if you know how to find it.

Google (Scholar) it

Don’t get discouraged just because one database says you need to pay for a specific study. Search for the title of the study (or a portion of the title with an author’s last name) on Google Scholar , the Google-powered search engine for academic literature. If you’re lucky, you’ll see a result with an [html] or [pdf] link on the right-hand side of the page, which should link you to the full text of the study.

If for some reason the right sidebar link doesn’t work, you can also click the “All 11 versions” link at the bottom of each result block to see more sites that offer the paper. You could also try searching regular ol’ Google for the paper’s title, perhaps with the filetype:PDF operator as part of your search terms. This may help you find it on sites that aren’t crawled by Google Scholar.

Use browser extensions to your advantage

If you’re a journalist, student, or science nerd who finds yourself regularly hunting for full-text articles, you can streamline the process a bit with a browser extension called Unpaywall . It works with Google Chrome and Mozilla Firefox, and displays a small padlock icon on the right side of your browser window whenever you visit a page dedicated to a scholarly article. If there’s a paywall and the padlock is green, that means Unpaywall found a free version somewhere on the web, and you can click the icon to visit it immediately. In my experience, this doesn’t find much more beyond a Google Scholar search, but it’s a lot easier than performing manual searches all the time. Heck, even if a site isn’t paywalled, Unpaywall’s green icon is still easier than hunting for the “Download PDF” button on a given page.

A tool called Open Access Button does something similar. It’s browser-agnostic and has been around for a bit longer, so try both tools and see which you like better. I think Unpaywall feels a bit smoother, but Open Access Button’s maturity may help you find things Unpaywall doesn’t know about yet.

Check your local library

Many public libraries subscribe to academic databases and share those subscriptions with their constituents. You may have to head to the library’s physical location to get a library card, if you don’t have one already, but those are usually free or cheap. And from then on, you should be able to access a lot of your library’s resources right from your computer at home, including scholarly journals (not to mention other paywalled magazines like Consumer Reports). If your library doesn’t have access to the publication you’re looking for, they may even be able to get it through an inter-library loan . If you ever feel lost, don’t hesitate to ask a librarian—they probably know the process like the back of their hand, and will do their best to help you find what you’re looking for.

If you’re a student, your school or university likely has access to more databases than you can shake a stick at (not to mention hordes of physical journals you can hunt through). If you aren’t a student but have a college nearby, ask them if they offer fee-based library cards—you may be able to pay for in-house access to their vast resources.

Email the study’s author

Finally, if you can’t find a paper anywhere online, you might be able to get it directly from one of the people who wrote it. The money earned by those paywalls doesn’t go to the researchers—it goes to the publisher, so authors are often happy to give you a copy of their paper for free (provided they’re allowed to do so).

Finding their current email address is the hard part. Papers will often contain an email address you can contact for questions, but if this becomes out of date, you’ll have to do a little hunting. Find the university or organization the researcher currently works for, not the one they worked for when the study was first published. A little Googling can usually point you in the right direction, but sites like ResearchGate and LinkedIn can also help. Some researchers have a personal website that may be up to date, as well, and in some cases, may even have their previous work available to download. But if not, shoot them a message, ask politely if they’d be willing to send you a copy, and thank them for their hard work.

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.

Introduction

Without access to subscriptions provided by a university library, many journal publications will be locked behind a paywall. Luckily Open Access Publishing and  self archiving  practices have lead to an increasing percentage of these articles being freely readable, published either as Gold Open Access, as preprints or in repositories through Green Open Access.

Preprint articles will not include peer review corrections, so if you are planning to cite an article it is important to refer to the final published version. 

Google Scholar can be the best place to start when looking for an article, as it automatically provides links to many Open Access articles, institutional and subject repositories, preprint servers and academic social networks, as you can see in the example on this page.

Browser extensions

If you come across a specific article which is behind a paywall, you can try to find an Open Access version by searching in Google Scholar or use browser extensions which give an alternate route.

All three examples below are designed to link to an Open Access PDF of an article directly from the publishers website. Each has a different interface and will produce slightly different results.

• Unpaywall Harvests Open Access content from over 50,000 publishers and repositories, and makes it easy to find, track, and use. Just install the extension to the Chrome browser for easy access to over 28 million open access articles.
• Open Access Button Free, legal research articles delivered instantly or automatically requested from authors.
• CORE discovery Backed by the CORE dataset of Open Access papers Core Discovery gives one click access to full texts from Institutional Repositories and other sources.

Your local library

Many public libraries in the UK can help you access journal articles through the Access to Research service. Free access is available to academic articles from most large publishers through library computers. This is a "walk-in" service, so you'll have to visit your local library in person and ask your librarian. A map of participating locations is available through the link below.

• Access to research

University repositories

Universities usually mandate that their authors deposit a copy of any articles they publish into their institutional repository. This will either be the final published version of the article, or an "accepted manuscript" (the peer reviewed text and author's final draft, without a publisher's typesetting). 

Many repositories are indexed by Google Scholar, so a PDF will appear available to download in the search results. If not, the 'all versions' button can provide links to other options. Here you can see an example of a PDF provided by the University of Reading's repository, CentAUR.

You can search across many repositories using search engines such as Google, Google Scholar or specialist Open Access tools such as CORE. You can also search a university’s repository directly if you are interested in the research of a particular author or a research department.

If you are struggling to find a specific repository try browsing OpenDOAR, the global directory of Open Access Repositories.

• CORE Aggregates open access research papers worldwide. Offers seamless access to millions of open access research papers, enriches the collected data for text-mining and provides unique services to the research community.
• OpenDOAR OpenDOAR is a directory of Open Access repositories with Global coverage. You can search the directory by name or browse geographically.

Pre-print servers

In some disciplines it is common to share research on a pre-print server before it is published in a journal. These are a particularly important source when you want to access the most recent research in a fast moving area. 

These papers have not yet been through peer review and so if you are using these as part of your studies, you need to be aware of this. Often fellow researchers may comment on the articles and, as a result, the paper may be modified and also later published in a fully peer reviewed form in a journal. Pre-print servers tend to be organised along subject lines and have become a significant communication outlet for new research for several subject areas. Items from pre-print servers are now included in bibliographic databases such as Scopus but should be clearly identifiable as non-peer reviewed. 

• ArXiv Large collection of free downloadable non-peer reviewed scholarly articles in Physics, Mathematics, Computer Science, Quantitative Biology, Quantitative Finance and Statistics.
• AgriRxiv Free, open access source of unpublished (non-peer reviewed) preprints across the agricultural and allied sciences. It is hosted and managed by CABI, an international, inter-governmental, not-for-profit organization. As well as agriculture, it covers soil science, water resources and environmental science.
• bioRxiv A free online archive for unpublished and non-peer reviewed pre-prints in the life sciences
• EarthArXiv A pre-print server containing non-peer reviewed papers in the earth sciences
• SSRN (Social Science Research Network) Leading social science online library of free full-text and abstracted scholarly research papers deposited by academics.

Researchers sharing their own articles

Researchers are usually keen to share their own articles. It's common for them to do this either on academic social networks (Academia.edu and Researchgate are the most common) or on their own personal websites. If you've exhausted all other options in this guide, consider contacting an author directly. They may well be happy to share it with you by email.

• ResearchGate ResearchGate is a commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators.
• Academia.edu Academia.edu is a for-profit American social networking website for academics. The platform can be used to share papers, monitor their impact, and follow the research in a particular field.

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

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

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

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

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

Search Engines and Databases

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

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

Search Engines

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

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

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

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

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

Selected Databases

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

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

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

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

Preprint and Data Repositories

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

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

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

Reach Out Yourself?

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

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

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