This document discusses Wikimedia residencies at the British Library and other UK cultural institutions. It provides examples of projects conducted by Wikimedia residents including algorithmically extracting illustrations from digitized books to upload to Flickr and crowdsourcing tags, hosting Wikithons to contribute information to Wikipedia articles, and supporting an exhibition on imaginary cities by uploading images of artifacts to Wikimedia Commons. The residencies aimed to increase contributions to Wikimedia projects from cultural collections and support open collaboration between institutions and online communities.
