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.

This extension does NOTHING on sites like New York Times, or Washington Post that all use paywalls.
not working.
Won't work on vast majority of articles unless they're already open-access, which defeats the purpose of this extension. Basically does little more than being a PDF downloader.
No sirve en un articulo de la Universidad de Cambridge desinstalando
Ikke hvad jeg forventede - men fint koncept.
It just sends you to pdfs
It doesn't work for all paywalled articles. If you're lucky you'll get some of them. Still worth a try if you're a student and looking for secondary sources for your assignment or paper.
Does not work on news articles. Useless. Don't care for research papers which are ALREADY FREE.
bei mehreren Seiten getestet und kein ging
looks like no longer work in 2022
