Libby is your mobile assistant for the online Librivox free audiobook library. You can listen any public book in the LibriVox system (yes it plays even in the background). LibriVox volunteers record chapters of books in the public domain, and then Librivox releases the audio files back onto the net for free. All Librivox audio is in the public domain, so you may use it for whatever purpose you wish. Bug fixes, supporting next/previous tracks, automatically switching to next track... This update still does not support offline listening. It will be supported in the next major version update.
