John Kirriemuir sent me a link to his presentation on gaming and on gaming and libraries, given at the Ticer summer school: Digital libraries a la Carte: new choices for the future. John spends more time on this stuff more than most, so his presentation is a nice overview [ppt].
There are other presentations of interest available on the website (I liked Ian Dolphin's overview of portal stuff [pdf], have done a separate entry on the FAST search presentation, and have updated my e-science post of yesterday with a note of a couple of relevant pieces.)
The Ticer Summer School has become a longstanding feature of the library landscape and has an international flavor. I have been surprised over the years not to see it replicated elsewhere.
