Unpaywall Browser extension11 April 2017
Unpaywall is a browser extension which adds an icon to your screen that lets you know if the full text of the article you are trying to view is available Open Access. You can add the extension to Google Chrome or Firefox and click on the icon to check for a link to an Open Access version – it’ll add an open padlock icon to the right of the screen, which will take you to the full text.
The extension works using DOI’s – so if there is no DOI- the plugin won’t work.
