The third Great Wikimarathon will occur on Saturday, July 26. The Wikimarathon is a one-day event that unites art lovers around the world in an attempt to collectively fill in the gaps of contemporary art knowledge found on Wikipedia. The Wikimarathon is a recurrent and uncentralized happening that takes place on the 26th of a month, since marathons are 26 miles long.

Participants gather locally, at house parties and coffee shops in their neighborhoods, to brainstorm and create content on contemporary and new media artists and programs. These small local groups then gather online in an open chat to streamline productivity and help each other edit their Wikipedia posts.

Organized, in part, by senior fellow Steve Lambert, R&D OpenLab fellow Michael Mandiberg, and Eyebeam alumni.
