Today’s Open Access news is about the Unpaywall browser extension for Firefox and Chrome.
These nifty browser extensions make use of the Unpaywall database of over 24 million free, legal, scholarly articles. Metadata from over 50,000 publishers and institutional repositories is harvested to the database.
The extension sits in your browser and shows you a green tab indicating that an OA version is available when you visit sites that have paywalled content.
Note: LibKey Nomad uses the Unpaywall database too, but also provides links to full text via Bond Library’s subscriptions. We recommend LibKey Nomad if you are a Chrome user, but if you prefer Firefox, then Unpaywall will still help you out.
