LibriVox - founded in 2005 - is a community of volunteers from all over the world who record public domain texts: poetry, short stories, whole books, even dramatic works, in many different languages. All LibriVox recordings are in the public domain in the USA and available as free downloads on the internet. If you are not in the USA, please check your country's copyright law before downloading.
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?
LibriVox volunteers record chapters of books in the public domain, and then we release the audio files back onto the net. They are a totally volunteer, open source, free content, public domain project.
