If you attended the recent Gaming, Learning and Libraries Symposium, you probably saw someone running around between sessions starting and stopping recordings. That was me. Almost all of the sessions were recorded and will eventually be available online for your listening pleasure.
The first recording, Henry Jenkins' excellent keynote talk "What Librarians Need To Know About Games, Media Literacy and Participatory Culture", is now online. His slides are available on the wiki page as well. Follow along at home!
The recordings were done through the PA system for each room with iPods and Belkin TuneTalk. Jenny Levine is editing them, most likely with Audacity. The first one came out pretty well, if I do say so myself. I read the little tag at the end too.
Keep an eye (or an ear) out for more session recordings in the future.
