The Open Access Button is a browser bookmarklet which registers when people hit a paywall to an academic article and cannot access it. It is supported by Medsin UK and the Right to Research Coalition. A prototype was built at a BMJ Hack Weekend. All code is openly available online at GitHub. A beta version of the Open Access Button was officially launched on 18 November 2013 at the Berlin 11 Satellite Conference for Students & Early Stage Researchers. It records instances of hitting a paywall, and also provides options to try to locate an open access version of the article. In April 2014 a crowdfunding campaign was started to build a second version. More information...
