I, too, am a library borrower. I use some iTunes AppleScripts to convert them into m4b's or whatever it is that lets you bookmark them. I just started doing it this way (used to use MP3 at about 32kbs/mono as I have a CD based MP3 player in my car) so that I would have an excuse to buy an iPod. (Shuffle or refurb 1G mini, not sure yet).
