Manifesto Site: <https://manifesto.wiki> Big Data & Society Commentary: < https://journals.sagepub.com/doi/pdf/10.1177/20539517251357292> In association with the Wikihistories project led by Heather Ford, we are pleased to announce the launch of the Manifesto for Wikipedia Research (< https://manifesto.wiki/>). This manifesto is the result of a collaboration between academics interested in furthering a research approach to Wikipedia and Wikimedia that draws on the humanist tradition, takes Wikipedia's importance seriously, and is responsive to Wikipedia's changing role as public knowledge infrastructure. We have also co-authored a commentary in Big Data & Society called "Uniting and reigniting critical Wikimedia research" < https://journals.sagepub.com/doi/pdf/10.1177/20539517251357292>. It explains each of the 10 calls-to-action and provides a bibliography and research questions of recent work to help others get started on critical Wikimedia research. Please get in contact with me (Steve Jankowski s.jankowski@uva.nl) if you have questions or would like to be part of a research network that is being set up to support the work of this manifesto. Sincerely, Steve Jankowski Assistant Professor in New Media Histories University of Amsterdam
