Get full text of scholarly articles as you browse. When you view a research article, Unpaywall automatically looks for a copy in our index of 20 million free, legal fulltext PDFs. If we find one, click the green tab to read the article.
Unpaywall points you to legal, author-posted manuscripts that are hosted on university and government web servers. We are pointing to versions that have been posted with the full and explicit authorization of the publishers themselves.
These free, author-posted manuscripts are often called "Green Open Access" and are a longstanding and completely legal part of the scholarly communications ecosystem. The majority of scholarly journals permit authors to "self-archive" their papers on university and government web servers. It's these legally self-archived papers that Unpaywall helps users find. Any papers posted outside of publisher permissions are NOT included in our index.

Works like a charm!
Works really well. Of course, it doesn't always find a free version of the article but it often does Very helpful!
It doesn't work; it doesn't show at all.
Didn't work for me.
It generally works nicely and is very convenient! However, Google Scholar can often find papers not found by this extension.
Doesn't check for all free papers Often Google Scholar + ResearchGate yields better results for free legal papers.
Incredibly simple. Vastly better than the alternative. I've saved hours in avoiding manual searches in the few months I've had this.
Science needs to get more centralized.
Works suprisingly often. Free research to free your mind!
