DENVER — Women gathered at Leon Art Gallery Saturday afternoon to shrink an online gender gap.

Wikipedia, which bills itself as the "free encyclopedia that anyone can edit", is primarily edited by men. An entry on the website says they make up 90 percent of its volunteer editors.

"Wikipedia for one is just one of the most visible and publicly accessible ways for people to learn about any topic," Kate Crowe said.

She's President of the Board for ArtHyve, a local art archive group.

"So if you're not on Wikipedia, you're less visible inherently," she said.

To address that problem, ArtHyve followed the lead of Art and Feminism, an international campaign to close the Wikipedia gap between men and women. Every March, they bring women together for edit-a-thons and teach them how to become wiki-editors.

"Having more women in the community writing and supporting women artists... that all matters," Crowe said.

It's not easy.

"It's a little complicated as far as the user interface," Araceli Torres said.

She's always used the site as a reference, but never added anything to it until the edit-a-thon.Torres focused on women of color and LGBTQ artists.

"Documenting those spaces is very important," she said. "A lot of that history is lost. It's intentionally destroyed or it's just overlooked."

Creating an article from scratch can be tough, because physical encyclopedias and other reference books have a gender gap, too. Wikipedia typically requires at least three published sources about someone before they're considered notable enough for an entry.

"Having more editors who are women who are deciding who is sufficiently notable is another way of addressing that imbalance," Crowe said.

Saturday's edit-a-thon didn't wipe out that imbalance in one swing, but Crowe says it's a step in the right direction.

"It's an uphill battle, but it's not an unwinnable uphill battle," she said.
