*Wikipedia Academy: Research and Free Knowledge.* *June 29 - July 1 2012, Berlin.* http://wikipedia-academy.de/2012/wiki/Main_Page The free online Encyclopedia Wikipedia answers questions of millions of users every day. Wikipedia's mere existence, growth, (social and technical) functioning and quality also raises an enormous number of research questions. The "Wikipedia Academy 2012: Research and Free Knowledge" provides a platform for the research community and the Wikipedia community to connect, present, discuss and advance research on Wikipedia in particular and on free knowledge in general. The Wikipedia Academy 2012 is organized by Wikimedia Deutschland e.V. in collaboration with the Alexander von Humboldt Institute for Internet and Society and Freie Universität Berlin. The conference will take place in Berlin, June 29 to July 1, 2012. The event will be open to all interested parties and features a variety of session formats, ranging from panel discussions and tracks with traditional paper presentations to break-out sessions, lightning talks, poster presentations and a science fair.
