Edit-a-thon

Wikipedia edit-a-thons have taken place at Wikimedia chapter headquarters; accredited educational institutions, including Sonoma State University, Arizona State University, Middlebury College,^[1] and the University of Victoria; scientific research institutions such as the Salk Institute for Biological Sciences;^[2] and cultural institutions, such as museums or archives.

Several Wikipedia edit-a-thons have been held during the COVID-19 pandemic adhering to social distancing measures.^{[citation needed]} These events have been held online using synchronous voice and video chat as well as through asynchronous message boards and forums.^{[citation needed]}

The events have included topics such as cultural heritage sites, museum collections, women's history, art, feminism, narrowing Wikipedia's gender gap, and social justice issues.^{[3][4][5][6][7][8]}

Women, African Americans, and members of the LGBT community are using edit-a-thons to bridge the gap in Wikipedia's sexual and racial makeup^[9] and to challenge the under-representation of Africa-related topics.^[10]

Some Wikipedia edit-a-thons have been organized by Wikipedians in residence. The OpenStreetMap community has also hosted several edit-a-thons.^[11][12]

• The "Wiki loves SDGs" initiative held a week-long online edit-a-thon on topics around the Sustainable Development Goals. The event took place online in September 2020 during Global Goals Week. It was organized by Project Everyone, an NGO in the UK, and had around 300 registered participants, 108 active contributors and 64 new editors. Most of the participants were from developing countries and seven out of the nine prize winners were from Africa. The event focused on improving SDG-related content on the English Wikipedia (some improvements were also made to the Spanish, Macedonian,^[13] Catalan and Portuguese Wikipedias). About 500 articles were improved.^{[14][circular reference]} Jimmy Wales attended the closing ceremony and presented the nine awards to the most engaged volunteers.^[15]

• Since 2014, Art+Feminism has held world-wide edit-a-thons annually to expand the histories of women, feminism, and arts found on Wikipedia, and to dismantle the biases on how women are represented online. 2019 marks the expansion of the movement to include "gender non-binary activists and artists".^[18]
• The global Ada Lovelace Day Edit-a-thon, an initiative to improve the diversity of Wikipedia articles, was co-created by Carol Ann Whitehead and Google Expert, Susan Dolan. It took place on October 9, 2019,^[19] in Manchester at The Pankhurst Centre.^[20][21][22]
