[Air-L] finding appropriate literature

Hi all I need help in finding appropriate literature (German or English). I have been teaching a course in "power structures on the internet" (digital culture, beginner's level), and promised the students help in finding literature for their assignments (which they could choose freely). There are two projects were I would still need to find something to give them. 1. Theoretical philosophy. The student wants to write about ontology in online communities. 2. The impact of becoming an administrator/moderator/gamemaster (online forums/games) on IRL behavior: The connection between (possibly anonymous) being powerful online and having a (possibly different) personality offline. Thanks a lot! - Daniel
