An inspiring example of collaborative OER creation is provided in this article [https://www.simonsfoundation.org/features/foundation-news/marathon-editing-brings-new-rigor-to-wikipedia-physics/]. At an American Physical Society meeting in June in Columbus, OH (The Ohio State University) the APS and the Simons Foundation brought together experts for an edit-a-thon to create new articles and make existing Wikipedia physics articles better. In a 3-hour session, 24 physicists joined three group leaders who were expert Wikipedia editors. Examples of articles edited or created in this intense session are, Speed of Light and Quantum Feedback. The article notes that the editors found The Wikipedia Adventure to be a useful tutorial for editing Wikipedia articles.
