Mendeley now has an open access search filter check-box for its catalogue search. Although unfortunately it currently considers JSTOR articles to be open access. For most of us they’re not, beyond the first page.


Europeana has the same problem, containing linked records pages for JSTOR content which isn’t open and public (e.g: “History of the churches of India” – Europeana links to it, it’s public domain, but JSTOR has the only copy and wants $10 to access it).
