Harris County Public Library has ebooks and audiobooks available online as well as ordering DVD's, books, and tapes for pickup at your favorite branch library. My brother uses this as a cheaper Netflix.

I haven't figured out how to download the audiobooks which was discussed at the last Houston Inner Loop SF Book group meeting but I can listen to books like the Time Traveler's Wife online. (You can also record it as it is playing with some free software you can find. That is built into Windows Media Player as well.)
