According the website, “LibriVox volunteers record chapters of books in the public domain and release the audio files back onto the net. Our goal is to make all public domain books available as free audio books. We are a totally volunteer, open source, free content, public domain project.” So far, the following Booth Tarkington titles are available:

1. Alice Adams
2. Penrod
3. Penrod and Sam
4. The Turmoil

The following titles are in the works:

1. The Magnificent Ambersons
2. Seventeen

I can’t vouch for the quality of any of these recordings, but the site sounds like a cool idea!
