Online Audio Books
I may be a little bit behind. I just discovered through one of my many geek resources an online provider for public domain audio books -- LibriVox. With mature search capabilities and a growing selection of books, they cover a wide range of topics. Each book contains a link to the e-text as provided by Gutenberg. The even provide an RSS feed of New Releases.
I am currently downloading The Imitation of Christ, by Thomas a Kempis. Other interesting finds include P.G. Wodehouse, Geoffrey Chaucer, and William Shakespeare.
This site is a very nice distraction from the rest of the stuff that I normally look at online.
