Free Audio Books
Fortunately, there are a few sites that offer free audio books for your iphone, ipad and computer.
Most of these books are available in the free domain, meaning there is no copyright keeping you from downloading a free copy of the book, or a free audio version of the book.
Remember, current trending authors are not going to be in this group.
However, if you like classics, historical texts and enjoy discovering new books from the past, then you might just like to take a look at the list of providers.
About.com has compiled a list of nine... you can see them here.
