Description
Open Access Button helps you download the PDFs of the papers you need.
One Button. Every Paper.™
Open Access Button finds free, legal versions of academic papers when paywalls get in the way. If the research exists open, the OAB will find it for you.
When you view a scientific paper, OAB detects its DOI (Digital Object Identifier) and checks whether there is available legal open access version.
Click the orange Open Access Button extension to download the PDF.
Knowledge yearns to be free.

The extension can be slow and unresponsive at times, taking too long to search for open access versions before giving up.
