P In a feminist bookstore in Madrid, 17 women gathered in the back room, engrossed in their laptops, sharing snacks, chatting, and laughing. The room was filled with the sounds of typing, periodically interrupted by enthusiastic applause marking milestones in the group’s mission to close one of the world’s most persistent gender gaps.

Only about 15 percent of Wikipedia’s content, including biographies, focuses on women, explains Patricia Horrillo, who has dedicated the past decade to cultivating a community of Wikipedia editors committed to creating content that highlights women.

Groups like Spain’s WikiSfera, Italy’s Wikidonne, and Switzerland’s Les Sans Pages have emerged globally to address this gender gap issue on Wikipedia.

The Wikimedia Foundation acknowledges the historical biases within Wikipedia and the need for more diverse contributions to address these gaps. Organizations like Horrillo’s Wikiesfera have received support to help bridge this divide and give visibility to women’s achievements.

Encina Villanueva participated in a Wikipedia content creation workshop at La Fabulosa bookstore, where she emphasized the importance of recognizing women’s accomplishments beyond their appearances or associations. She has seen the impact of her work reverberate across the internet, amplifying women’s stories.

Celia Hernandez-Garcia, a middle school teacher, joined Wikiesfera to highlight women’s achievements often overlooked in textbooks. With no prior tech skills, she embraced the opportunity to elevate women’s narratives through Wikipedia, impacting her students’ understanding of history.

Horrillo’s vision for Wikiesfera began a decade ago, aiming to empower individuals to contribute to Wikipedia by addressing barriers beyond technical knowledge. Despite challenges, the group continues its efforts to increase female representation on the platform.

Though obstacles such as a lack of sources documenting women’s achievements persist, Wikiesfera remains committed to bridging the gender gap on Wikipedia. Each article added during their sessions represents a step towards rectifying the systemic invisibility of women in historical narratives.
