Symposium. Part of the activist archival event: "We Can [Edit] Copenhagen: Feminist Wikipedia edit-a-thon" (March 8-9, 2015). Women make up an estimated 16% of Wikipedia editors worldwide. While the reasons for the gender gap are up for debate, the practical effect of this disparity, however, is not. Content seems to be skewed by the lack of female participation. That means that while Wikipedia is essentially the most radically open encyclopaedia the world has ever seen, voices and perspectives are still being left out. This symposium seeks to engage with, and respond to, the wide range of questions that the Wikipedia gender gap example provokes, from archival literacy and labour issues to archival power distribution and critical potential. Organized by Nanna Bonde Thylstrup (KU) and Kristin Veel (KU) in cooperation with Maibritt Borgen (Yale University) and Renegade Runners with support from: "The Past's Future: Digital Transformations and Cultural Heritage Institutions”; "Uncertain Archives: Adapting Cultural Theories of the Archive to Understand the Risks and Potentials of Big Data" (VELUX); Wikipedia Gender Campaign (YDUN). Speakers: Keynotes: Jonathan D. Katz (Buffalo University), Joanna Zylinska (Goldsmiths) Sarah Kember (Goldsmiths). Plenary speakers: Mathias Danbolt (Department of Art and Cultural Science, University of Copenhagen) Marianne Ping Huang (Arts, Aarhus University) Rikke Frank Jørgensen (The Danish Institute for Human Rights) Jens-Erik Mai (Royal School of Library and Information Science, University of Copenhagen) Anders Søgaard (Centre for Language Technology, University of Copenhagen).
