Hi,
Registration for this collaboration event at the British Library has opened today and has yet to be promoted to the general public. Sign up early if you would like to take advantage of full access to the English and Drama unique collections (some of the archives suggested have yet to be officially catalogued) with supporting advice from the UK's leading curators and researchers who are eager to help improve Wikipedia's (and sister projects) depth of coverage. Details at http://uk.wikimedia.org/wiki/Editathon,_British_Library
The event runs from 10am-5pm on Saturday 4th June and registration will be limited to a maximum of 30. The event has been organized in partnership with Wikimedia UK as part of our UK GLAM initiative. Your comments for improvements or suggestions for alternative British Library events are welcome on the registration talk page.
A long term Wikipedia collaboration page can be found at http://en.wikipedia.org/wiki/Wikipedia:GLAM/BL
