Announcing Unpaywall: unlocking #openaccess versions of paywalled research articles as you browse | Everything open | Scoop.it
Today marks the official launch of Unpaywall, a web browser extension that links users directly to free full-text versions of research articles. Heather Piwowar and Jason Priem of Impactstory, the team behind Unpaywall, report on the successful pre-release phase, and explain how two decades of investment, a slew of new tools, and a flurry of new government mandates have helped build a powerful momentum behind green open access.

Today we’re launching a new tool to help people read research literature, instead of getting stuck behind paywalls. It’s an extension for Chrome and Firefox that links you to free full-text as you browse research articles. Hit a paywall? No problem: click the green tab and read it free!
