Free Resources: eAudiobooks
There are a number of sites that offer free eaudiobooks. Many of these eaudiobooks are of works that are in the public domain. In other words, you probably won't find the hottest best sellers or many new books on these lists, but some of them do have fairly extensive collections, often in multiple languages. Also, most of them offer downloads in multiple formats, so should work on most devices including iPods.
