The gender gap just got a little smaller. Thanks to the fourth annualArt+Feminism Wikipedia Edit-a-Thon, over 6,500 women artists have new or expanded Wikipedia entries. Across over 200 events held around the world in March, Women’s History Month, 2,500 participants did their part to fight the Wikipedia gender gap by improving online resources about women artists.

The edit-a-thon was founded in part to increase female editorship on the site, in response to a 2011 survey that found that that less than 10 percent of contributors were women. According to the event organizers and Art+Feminism, this year’s initiative nearly doubled the impact of the 2016 iteration.

“We were heartened by the response to our call to arms to fight against disinformation and fake news with facts,” said Art+Feminism organizers Siân Evans, Jacqueline Mabey, McKensie Mack, and Michael Mandiberg. “We continue to be inspired by all the dedicated folks who make room in their busy schedules to share skills and improve a collectively held resource like Wikipedia.”

Edit-a-thon events were held at some of the world’s biggest art institutions, including New York’s Museum of Modern Art; the Smithsonian American Art Museum in Washington, DC; and the Uffizi Gallery in Florence. Alternative organizations such as the Open Foundation West Africa in Accra and Transgender Europe in Berlin also took part.
