A friend recently told me about a place he goes to often on the web: http://librivox.org/.This site is a great place to listen to audio books! There is a vast collection of public domain literary works, read by volunteers. You can volunteer to read a work, or you can listen to one of the books read by others. The site has been up for three years, and is entirely free. Next time you are thinking of purchasing an audio book, try looking it up here first!
