With roughly half the world’s population, it follows that the world’s collective source of basic information known as Wikipedia should derive more than 10% of their information from women. Clearly, that is not the case. The international editorial movement Art+Feminism aims to change that by hosting an annual edit-a-thon to teach aspiring editors to the world’s online encyclopedia how to edit, update and add to the content on the site. Locally, the UNM Art Museum, in conjunction with UNM Libraries, the Tamarind Institute and The Necessarian will host an edit-a-thon this Saturday from 10am to 2pm at the UNM Art Museum on the University of New Mexico Albuquerque campus. This event is free and open to the public.
