Tools to easily access Open Access fulltext articles

These tools are extremely useful to discover and access Open Access articles in full-text

Why do researchers use EndNote Click?

Researchers are able to access millions of research paper PDFs in one click on Web of Science, Meta, PubMed, arXiv, Scopus and thousands more academic websites. Save time navigating paywalls, logins and redirects. 

EndNote Click helps you get to your full-text PDFs faster by securely connecting you to your library’s journal subscriptions and open access content.


Once you have the PDF, you can easily export it to your favourite reference management tool or download it to your desktop. EndNote Click integrates with Mendeley, EndNote, Dropbox and Zotero

What is the Open Access Button?

The Open Access Button is a browser-based tool that lets users track when they are denied access to research, then search for alternative access to the article.

How and why would you use the Open Access Button?

Each time a user encounters a paywall, he simply clicks the button in his bookmark bar, fills out an optional dialogue box, and his experience is added to a map alongside other users. Then, the user receives a link to search for free access to the article using resources such as Google Scholar. 

The Open Access Button initiative hopes to create a worldwide map showing the impact of denied access to research. Every person who uses the Open Access Button brings us closer to changing the system.

Unpaywall finds the kind of articles you'd see in peer-reviewed scholarly journals like Science or PLOS One, plus pre-publication versions of similar work from preprint repositories like arXiv. Specifically, it looks for articles with a kind of identifier called a DOI

Unpaywall harvests Open Access content from over 50,000 publishers and repositories, and make it easy to find, track, and use.

Is unpaywall legal?

Yes! We harvest content from legal sources including repositories run by universities, governments, and scholarly societies, as well as open content hosted by publishers themselves. We do not harvest from sources of dubious legality like ResearchGate or Sci-Hub. If you ever encounter content indexed by Unpaywall that is posted in violation of copyright, let us know and we'll remove it immediately.
