LibriVox [Audiobook, Online Resource]
LibriVox is a free source of public domain audiobooks read by volunteers from around the world. Most of the books are in English, but other languages are available as well with many titles in French and German and a not insignificant number of recordings in Ancient Greek. Titles for children and adults are available. I recommend starting with the Adventures of Sherlock Holmes and Alice’s Adventures in Wonderland, both of which are available in variety of version by different readers.
