Gender Bias is a well-known and documented issue on Wikipedia, both in content and editorship (due to the larger issue of Systemic Bias).
The Art+Feminism organization is a leader in the online activist community that aims to address representation issues in the arts related to gender, race, LGBTQ, and more in the public knowledge realm.
According to Wikipedia's only study of its user community, less than 10% of Wikipedia's editors identify as cis or trans women.

You (along with everyone else) have the ability to edit Wikipedia! You may do this on your own, from the comfort of your home or by attending Wikipedia Edit-a-Thons in your area. Cline Library will host our 3rd annual Art+Feminism Wikipedia Edit-a-Thon on April 27, 2019 (more info will be posted to this guide), in partnership with NAU's Associated Students for Intersectional Feminism.
