The LibriVox Free Audiobook Collection (Internet Archive).Why Public Domain and not a Creative Commons license?.Community service / volunteering for credit.We are a totally volunteer, open source, free content, public domain project. LibriVox volunteers record chapters of books in the public domain, and then we release the audio files back onto the net. LibriVox is a hope, an experiment, and a question: can the net harness a bunch of volunteers to help bring books in the public domain to life through podcasting? 3.3.3 Recording Resources: Non-Technical.
