lterrat's bookmarks 2017-04-27
From Google Translate: "Unpaywall is a new tool available to Internet users that allows them to find the open access version of the scientific articles. This is an extension available for Chrome and Firefox browsers that uses the oaDOI API . It indexes 90 million articles and identifies the versions of open access articles thanks in particular to DOAJ, CrossRef and DataCite, to open archives and to BASE. Simply copy and paste the DOI of a document and oaDOI looks for a possible open source version.
Unpaywall and oaDOI are developed by Impactstory , a non-profit organization supported by the National Science Foundation and the Alfred P. Sloan Foundation.
A number of tools are listed in the article Open Access: tools to help you."
