I bought two Kindles (one DX, one regular) for preloading content and circulating. Also, I'm sort of experimenting with something else -- cheap netbooks with preloaded content (library tutorials, bookmarked pages, etc.). I'm going to theme both types of technologies -- for Kindles, perhaps one will be psychotherapy and diversity, the second mythology and religious studies. Also, the netbooks will be themed to start -- general research, advanced research, copyright, course development (for faculty only). I have to get IT on board for the netbooks, which has been tricky as they're short staffed. Basically the netbooks have to be reset-able so that when they are returned we can wipe out anything that may have been downloaded; setting restore points, perhaps? Not sure, still working on it.
Will add a Sony ereader if the Kindles do well and may add cheap mp3s loaded with faculty lectures. There will be release forms/agreements that patrons will have to sign for all tech checkouts. Basically a catch all for each type of technology that explicitly states how expensive replacement costs are. Working on that too.
Thoughts?
