Best Websites to Download Research Papers for Free

Today, the average cost of downloading a research paper is roughly around $30. This is because of the present model, which has publicly funded research locked behind paywalls established by publishers, who don’t really add much extra value by themselves. As a result, many researchers and other people who are aware of this issue have been looking for a better alternative to this existing system.

In fact, some people even go to the length of claiming that this model is one of the greatest hindrances on the path of human progress today.

However, discussing that is not the purpose of this article. Rather, I intend to show you how to avoid paywalls and download research papers for free. Please be warned that accessing these sites is illegal in many countries, so be sure to conceal your identity by using a VPN like NordVPN.

Returning to the good part, in this article, I will feature the 11 (not just 10) best websites that allow you to download quality peer-reviewed research papers without paying the exorbitant fees charged by the most prominent publishers today.

TL;DR

Start with Unpaywall (browser extension, 100% legal). If you can’t find what you need, try OA.mg or CORE. For hard-to-find papers behind paywalls, Sci-Hub has 85M+ papers but requires a VPN in most countries. For books and textbooks, Library Genesis is the go-to.

Best Websites to Download Research Papers for Free (Legally)

Disclaimer: Before we begin, I should mention that #1 & #2 websites listed here are technically illegal in some countries. However, thousands of academicians and researchers have praised these websites and believe that their services are not only justified but also important for the betterment of our world.

At the end of the day, it’s up to you to decide what’s right and wrong. Let’s now take a look at my choices for the best websites to download research papers for free.

Sci-Hub

You can download almost 99% of all scientific papers and articles in existence on Sci-Hub.

Sci-hub allows you to download research papers for free

Note: Using Sci-Hub may not be legal in your country. Also, you will require a VPN to use this website. I recommend using NordVPN for the purpose.

Sci-Hub was originally launched by Alexandra Elbakyan, a Kazakhstani graduate student, in 2011. It is a website known for providing access to various academic articles and papers using educational institution access and its own collection of downloaded articles and papers. In fact, you can download almost 99% of all scientific papers and articles in existence on Sci-Hub.

Needless to say, Sci-Hub is one of the most incredibly controversial websites in existence. On numerous occasions, people have targeted it for copyright infringement. Many internet service providers (especially in developed countries) have blocked it at present.  Sci-Hub’s own statistics show that the chances of a request for download being successful are 99%. It processes more than 200,000 requests every day.

Sci-Hub works in a notably different way than most other platforms listed here: students, researchers, and other academicians donate their institutional login to Sci-Hub. When you search for a paper, Sci-Hub downloads it through that account and stores a copy of it on its own servers.

Research Paper Paywall Problem - Cost and Statistics Infographic

You can download research papers from Sci-Hub by following the steps below:

  • Visit Sci-Hub’s webpage. (Use a VPN to access it if blocked.)
  • Type the full name, DOI, or URL of the research paper you are looking for.
  • Click the red “open” button.
Important

Both Sci-Hub and Library Genesis operate in a legal gray area. Many ISPs block these sites. If you choose to access them, use a VPN like NordVPN to protect your privacy. Always check your country’s laws regarding academic paper access before proceeding.

Library Genesis

Library Genesis or LibGen is a vast database harboring a whopping 58 million science magazine files and more than 5 million free papers, complete journals, articles, and non-fiction books.

Library Genesis homepage for free research paper downloads

Note: You may require a VPN to use this website too. I recommend using NordVPN or AtlasVPN for this purpose.

In 2015, it was sued by Elsevier – one of the world’s most well-known publishers of medical, technical, and scientific research papers. However, that hasn’t led to anything as of now.

At present, many internet service providers have blocked Library Genesis. However, it is still accessible by virtue of its numerous mirrors.

You can find a research paper or book on Library Genesis by following the steps given below:

  • Visit Library Genesis’ official website.
  • Type the name of whatever you’re looking for into the search field, and click the “search!” button.
  • Click on the name of a book or research paper in the list of results, and choose one of the available mirrors.
  • Proceed to download the book or research paper and save it to your device.

OA.mg

OA.mg aims to make research more open and discoverable by providing direct download links to over 200 million research papers.

OA.mg research paper search engine

Its key mission is to help everyone become more productive at every stage of their academic work — from research to bibliography generation. By aggregating and combining all Open Access databases, they are able to guide you to the latest open access research as well as the research behind paywalls. If there isn’t a direct link, they’ll help you find a way to download it. 

You can find research papers using OA.mg by following the following steps:

  • Visit the following link: https://oa.mg
  • Enter your keywords or DOI number in the search field available over there.
  • Click the “search” button and wait for the results to turn up.
  • In the list of results, download any research paper you need by clicking the download link.

Unpaywall

21 million academic articles from more than 50,000 content repositories and publishers.

Unpaywall browser extension for free research papers

This is a colossal database that harbors over 21 million academic articles from more than 50,000 content repositories and publishers. The articles in database are mirrored from government resources and hence downloading those is legal.

The developers claim that they have around 80-85% of all scientific articles available in their archive. They are also supported by grants from the Alfred P. Sloan Foundation and the National Science Foundation.

You can use the Chrome extension to easily access them anytime. For that, you just need to follow the steps given below:

  • Visit https://unpaywall.org/products/extension.
  • Click the “Add to Chrome” button.
  • Click “Add to Chrome” on the Chrome Web Store page as well.
  • Wait while the extension gets installed.
  • Once you install it, the extension works automatically and turns up whenever you visit a paywalled research paper listed in Unpaywall’s open database. All you need to do is click the green Unpaywall button for the paper to open up immediately.

Unlike many other websites listed here, the services offered by Unpaywall are totally legal because it points to legal, author-posted manuscripts hosted on government and university web servers (generally known as Green Open Access manuscripts).

As a matter of fact, Unpaywall is integrated into several search platforms, library systems, and other information products all across the world. It has been helping make scholarship more readily accessible to people around the globe.

Pro Tip

Install both the Unpaywall and Open Access Button Chrome extensions together. Unpaywall checks for free versions automatically, while Open Access Button lets you request papers directly from authors when no free version exists. They complement each other perfectly.

Citationsy Archives

Citationsy Archives allows you to search for journal articles and papers, download them, and (obviously) cite them in your projects.

Citationsy Archives research paper search and citation tool

Citationsy is a free to use tool but there are some limitations with the free plan. For just $9.99 per month ($4.99 if you are a student), you can get unlimited citations, references, bibliographies, word export and more. Citationsy Archives offers only 3-days trial but if you use promotion code GAURAVTIWARI , you can get premium version for free for a whole month.

Citationsy institutional code input for free premium access
To use the code, just create an account and paste GAURAVTIWARI under “Institutional code” box.

Note that you can use Citationsy Archives with or without an account.

All you need is to enter a query, it will search for the same through all the research papers in the world and present the relevant matches to you. You can click on any of the results to see more details, and promptly site it from there itself.

This platform also enables you to download the paper through a few different, and completely legal, open access services.

Use Citationsy Archives from https://citationsy.com/archives/ 

Directory of Open Access Journals

Community-curated website that features several peer-reviewed, high-quality open access journals.

Directory of Open Access Journals homepage

The Directory of Open Access Journals (DOAJ) is a community-curated website that features several peer-reviewed, high-quality open access journals. It was launched in 2003 with about 300 journals in its possession. Ever since, it has grown to harbor more than 10,000 open access journals spanning all areas of science, social science, medicine, humanities, and technology. The number of free articles featured on this platform is growing every day.

The DOAJ is maintained by Infrastructure Services for Open Access (IS4OA) – a non-profit charitable organization that wishes to offer the benefit of openly accessible publications and data to the global community of users. It asserts that open and wide distribution and dissemination of knowledge wil greatly benefit the human society all across the world.

Similar to Unpaywall, DOAJ is completely legal and its website is funded by sponsors, publishers, and non-publisher members. In order to find and download free research papers, follow the steps given below:

  • Visit DOAJ’s official website.
  • Enter your keywords into the search field in there, and press Enter.
  • Choose the research paper you need to download
  • Just above the abstract, you’ll see the “full text” button. Click it.

Open Access Button

Leverages public repositories of research papers to make publicly funded research freely accessible to one and all.

Open Access Button browser extension

Open Access Button was founded in November 2013 by a group of students who were fed up of running into paywalls. It leverages public repositories of research papers to make publicly funded research freely accessible to one and all.

Open Access Button is quite similar to Unpaywall in terms of functioning. However, the two of them differ in one significant aspect: whenever Open Access Button notices that an article is not freely available, it automatically notifies the authors to share it by putting it into a repository. The more people try to find an article via this platform, the more requests an author gets.

You can use Open Access Button by downloading their browser extension. For that, simply follow the steps given below:

Don’t worry if you are not a Google Chrome user. You can still use the online version of Open Access Button by visiting the following link: https://openaccessbutton.org

Quick Poll

How do you usually access research papers?

PaperPanda

This free browser extension for Chrome grants you one-click access to various journal articles and papers in PDF format.

PaperPanda Chrome extension for free research PDFs

Basically, when you activate this tool, it finds the DOI of the paper from the present page and then proceeds to search for it. It begins by querying various Open Access repositories like OaDoi, SemanticScholar, ArXiV, and the Internet Archive.

The developers are working on a soon-to-be-released feature that allows you to set your university libraries domain in the settings. PaperPanda will then automatically search for the required paper through your library. If needed, you will be able to set a different custom domain in the settings.

I’ve included instructions for using this tool below:

  • Install the PaperPanda extension for Google Chrome.
  • Pin PaperPanda to your browser’s toolbar.
  • While visiting a page for a research paper, click the tiny panda icon in the toolbar.
  • PaperPanda will now find the PDF file for you. If needed, you can open “settings” and adjust the domain it uses to find your papers.
Legal Alternatives First

Always try legal platforms first: Unpaywall, DOAJ, CORE, and Open Access Button are all 100% legal and free. You can also email the author directly. Most researchers are happy to share their work. Only consider gray-area platforms as a last resort.

Education Resources Information Center (ERIC)

Contains not only journal publications but book sources and gray literature as well.

ERIC is a part of the United States Department of Education. It serves as a comprehensive archive of publications and is widely regarded as an excellent way of downloading research papers without paying a fee. It contains not only journal publications but book sources and gray literature as well.

Both the journal and non-journal material you’ll find over at ERIC are peer-reviewed and reliable. It adds new research publications sources to its index database system twice a year.

You can access ERIC by visiting its official website: https://eric.ed.gov/

Before submitting any research paper, run it through Sapling. It catches grammar mistakes, improves clarity, and suggests better phrasing. The AI-powered writing assistant works directly in your browser, so you can polish your paper as you write.

Frequently Asked Questions

Here are the most common questions I get about downloading research papers for free:

Is it legal to download research papers for free?

It depends on the platform. Websites like Unpaywall, DOAJ, CORE, and Open Access Button provide completely legal access to open access papers. Sci-Hub and Library Genesis operate in a legal gray area and are blocked in many countries. Always check your local laws before using any platform.

What is the best free alternative to Sci-Hub?

For legal alternatives, Unpaywall is the best option. It automatically finds free versions of papers as you browse. OA.mg aggregates over 200 million papers from open access databases. You can also try emailing the author directly, as most researchers are happy to share their work.

Do I need a VPN to access Sci-Hub?

In most countries, yes. Many ISPs block Sci-Hub due to copyright complaints from publishers. A VPN like NordVPN will let you access the site by routing your connection through a different country. It also protects your privacy while browsing.

Can I access research papers through my university for free?

Yes, most universities subscribe to major journal databases like JSTOR, IEEE, Elsevier, and Springer. If you are a current student or faculty member, you can access these through your institution’s library portal. Some universities also offer alumni access to certain databases.

What is Open Access and why does it matter?

Open Access means research papers are freely available online without subscription fees. It matters because most research is publicly funded through taxes, so many argue the results should be freely available to everyone. The Open Access movement has grown significantly, with many funders now requiring researchers to publish in open access journals.

How do I find a specific research paper if I only have the title?

Start with Google Scholar to find the paper’s DOI (Digital Object Identifier). Then paste the DOI into Sci-Hub, Unpaywall, or OA.mg. You can also search directly on platforms like ScienceOpen or CORE using the paper title. The PaperPanda Chrome extension automates this process.

Are the papers on these free websites peer-reviewed?

Most papers on these platforms were originally published in peer-reviewed journals. Sci-Hub mirrors papers from publishers like Elsevier, Springer, and Wiley. DOAJ specifically indexes only peer-reviewed open access journals. However, always verify the source and check for retractions before citing any paper.

Can I download textbooks for free using these websites?

Library Genesis (LibGen) is the most popular platform for free textbooks, with over 58 million files including textbooks, monographs, and reference books. For legal alternatives, check OpenStax for free peer-reviewed textbooks, or look for older editions that authors have made freely available on their personal websites.

Conclusion

It is common knowledge that research publication is an expensive field – both for researchers and readers. Most scientific studies are behind the paywall when the researcher refuses to pay the open-access publication fee. The average cost of downloading a research paper is about $30 – something not everyone might be able to afford. However, that’s what the websites listed in this article are meant to help you with.

However, before using any of these websites for downloading research papers for free, you must keep in mind that bypassing paywalls put up by paywalls is illegal in many parts of the world. Thus, you should consider using a VPN to protect your identity. Doing so extends a private network across a public network and allows you to send and receive data privately and securely.

Note that these are free research tools that allow access to many resources. But their content is not unique. It may not meet academic standards or individual needs. If you need original, high-quality work, consider hiring a professional academic writing service or working with a tutor at your university.

Disclaimer: This site is reader-supported. If you buy through some links, I may earn a small commission at no extra cost to you. I only recommend tools I trust and would use myself. Your support helps keep gauravtiwari.org free and focused on real-world advice. Thanks. - Gaurav Tiwari
