Public domain audiobooks from LibriVox.org, what a great idea! From their site:

LibriVox volunteers record chapters of books in the public domain and publish the audio files on the Internet. Our goal is to record all the books inthe public domain.

Kevin Kelly’s website has a great description of it given from contributor Paul Goessling:

Last year I took a cross-country road trip with my 10-year-old daughter, and we were greatly entertained by the free public domain audio books available from LibriVox, an online forum which connects readers (as in those who voice the text) to books, then makes the resulting audio files freely available to all. The library is strictly public domain material, but is very extensive. Most of the books we listened to were read by just one person (”going solo”), but readers can volunteer for individual chapters of books in progress. We listened to The Prince and the Pauper, The Mysterious Island, The Wind in the Willows, Five Children and It, and several selected poems and short stories. (Kudos to Timothy Smith for The Mysterious Island — a tour de force!). Online coordinators organize the readings, which are generally excellent. Some readers provide wonderful voices for each character; some simply read the text. The books are available for download from the website, or can be downloaded via iTunes, which we did and then listened to from the iPod in the car

In case you want to contribute to the community, here’s where to get started.
