We're holding an edit-a-thon in Copenhagen on the 8th of June, hoping to gather some ten Wikipedians and a similar number of GLAM professionals.
On the subject
1864 was 149 years ago, so we assume that a number of GLAM institutions will have anniversary exhibitions next year. This (hopefully) means that we can feed into their process now rather than going with the finished product next year. The year 1864 was chosen very much from a Danish perspective, as neither 1914 nor 1814 seem to gather much attention here.
Location and participants
The edit-a-thon will take place at the National Archives in Copenhagen. We have invited a wide spread of institutions. There will be a list here.
The event has been announced on Facebook and on Google+, and we hope to have people all over the world help with creating content in their respective languages - and to see local events.
