LibriVox: free audiobooks
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.
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?
To make all books in the public domain available, for free, in audio format on the internet.
Our Fundamental Principles
- Librivox is a non-commercial, non-profit and ad-free project
- Librivox donates its recordings to the public domain
- Librivox is powered by volunteers
- Librivox maintains a loose and open structure
- Librivox welcomes all volunteers from across the globe "
