I came upon this great blog by a computer whiz who's explaining to less wired-up reading teachers how we can use ipods in class. I'm sure all manner of adaptations are feasible and intend to try some.
A site you can join to download audiobooks onto your ipod, or onto your computer for direct listening or downloading in segments onto your ipod, is www.audible.com. It costs around $14 a month with a cheaper rate for the first 3 months. Advantage=you can get all the latest titles.
For loaning CDs and DVDs don't forget your library. They have catalogues and you can order titles that aren't currently on their shelves. Advantage= it's free.
