And while talking about other lives, those interested in thinking more about Second Life in an educational setting can follow the discussion on the Eduserv Foundation blog (second life on eFoundations) where this is a particular interest. They held a dual-world symposium (rl-sl does not quite have the ring about it that ac-dc does) recently around the theme Virtual worlds, real learning? See the debriefing and follow blog commentary via Technorati.
Andy Powell (aka Art Fossett) has a short video briefly describing Eduserv, the Foundation and its Second Life activities. Watch out for the discussion of, ahem, slashups (i.e. second life mashups), and the description of the recent Eduserv Foundation grants to projects exploring educational uses of Second Life.
Libraries are not ends in themselves, but serve the interests of the organizations of which they are a part. As university emphasis varies around research, education and career poles, we can expect to see libraries evolve to support those emphases more strongly.
