I found this via Lifehacker:
” Want a little (legally) free audio reading for your commute? Barnes & Noble is giving away nine free audiobooks in unrestricted MP3 format, so you can play or convert them for any use. Kurt Vonnegut, Jonathan Lethem, and even Mark Twain’s full “The Adventures of Tom Sawyer” are represented in the collection. Add them to your shopping cart (even though they’re listed at $0.01, they’re free at checkout), provide a credit card number or select to pay by PayPal acount (whether or not you really have one), and you’re on your way. It’s like a fire sale on the net this month! [Audiobook Free Downloads at B&N via The Cheapskate] ”
Personally I listen to these more for the voice over artist’s technique and delivery.
