Metadata Games, the National Standard open source crowdsourcing game platform, was used with over 45 Collections represented at 11 Institutions. It included tens of thousands of media items (images, audio, video) that have generated over 315,000 tags, with even outlier images garnering over 200 tags each.
 
Past collaborations included the British Library, Boston Public Library, The Open Parks Network, Digital Public Library of America, and the American Antiquarian Society, among others.
