Open Access Button
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.
The second version of the button was launched on 21 October 2014 as part of open access week.
In February 2015 the Open Access Button and its co-founders, David Carroll and Joseph McArthur, were awarded a SPARC Innovator Award by the Scholarly Publishing and Academic Resources Coalition.
The third version of the button was launched on 28 October 2016, again, as part of open access week.
