What is "librivox"

LibriVox is a group of worldwide volunteers who read and record public domain texts creating free public domain audiobooks for download from their website and other digital library hosting sites on the internet. It was founded in 2005 by Hugh McGuire to provide "Acoustical liberation of books in the public domain." As of April 2015 it had 8,664 items in its collection. Most releases are in the English language, but many non-English works are also available. There are multiple affiliated projects that are providing additional content. LibriVox is closely affiliated with Project Gutenberg, and the Internet Archive that hosts their offerings.

The LibriVox objective is "To make all books in the public domain available, for free, in audio format on the internet".
