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.
First paywall breaker that actually worked for me, thanks!
No funciono con The Economist
An incredible asset this past semester for me. I was able to access way more research than I would have been on my own and it definitely reflected in my grades!
Amazing
It actually works… So far it’s 1 for 1. Even if it doesn’t work for any other scholarly articles it was still worth the download. Fantastic!
I would like it to open unpaywalled article ajacent to the current tab. Not after the rightmost tab.
super!
I downloaded to try to unlock Wall Street Journal. Doesn’t work. Also doesn’t work on any psychology articles I looked for.
It’s awesome, no need to spend time trying to find a free pdf. It even find stuff I’m not able to find when I take the time. Very impressive. Thank you so much for sharing your time and talents!
I’ve installed less than an hour ago, and I’m in love with it already!!
This even outperforms Sci-Hub sometimes! Excellent tool.
Not working for nytimes.com
Love it! It worked on all the papers I tried today. Victory for the non-medical-professional amateur-armchair-scientist geeks. Thanks so much!
Ottima estensione per trovare facilmente i PDF durante l’uso normale, in qualunque sito ci si trovi. Non devo più lanciare una caccia al tesoro ogni volta che visito un editore o archivio istituzionale per capire dove sia il pulsante che porta all’eventuale PDF! Il 50 % delle pubblicazioni scientifiche recenti è disponibile e facilissimo da scaricare grazie a tutte le università che hanno messo a disposizione le opere in accesso aperto verde.
Doesn’t work….
A simple Google Scholar search revealed free instances of a semi-popular article referenced in a tech news outlet that the extension did not locate. This extension is not worth downloading.
Great Extension!
Keep fighting the struggle for freedom of free information!
Not working. Nothing shows.
Utilissimo per trovare copia degli articoli pubblicati, in giro per il mondo.
seems like scihub is down for me. what to do?!?!?!?
before despair could set in, installed unpaywall and had access to the document i desired instantaneously!
works as advertised!
open everything!
哪些网站可以用呢，我咋至今没见到一个绿色按钮呢
A must have app ahead of any scientific review.
Fantastic! I love it – it makes me happy. A happy little nerd-ling.
要是插件支持中文就更好了
Easy to use extension, giving access to many paywalled journal articles.
