Open knowledge as it relates to questions of justice and collective action is about more than access. Communities seeking to share and publish with effectiveness in mind can take many different forms and modes, based on their goals, material, and readership. The microcosm of open knowledge communities currently operating on PubPub, an open access publishing platform developed by Knowledge Futures, is an excellent example of this. Join us during OA Week 2022 for a fun, informative, and inspirational Pub Crawl! This one-hour event will feature 5-minute talks from seven PubPub communities publishing on topics related to climate change and climate justice with time for questions and discussion at the end. Participating Communities will take attendees on a brief tour of their publishing spaces, discussing their goals, motivations for sharing openly, and any insights about their processes and collaborations toward the end of learning from one another and promoting greater open sharing in this space.
