We’ve highlighted free audiobooks before, but Books Should be Free is worth mentioning since their site is especially well organized and easy to use. While browsing, I found Tom Sawyer, Price & Prejudice, The Art of War, Sherlock Holmes and many other great books for homeschoolers & other students.
The books are read by volunteers, so accent and voice will vary. You may download the audios in different formats, such as via iTunes or by mp3 download. You may also listen to the audios on the website.
