I found this site at the recommendation of a friend. It is kinda like an internet library. It is an attempt to make public domain materials available free of charge. They have lots of out of print books that have been scanned, and also access to lots of free audio books. not all of the audio books are of good quality. Some are read by a computer, ghhhplt! But some others are well read by volunteers. There is lots of other stuff too, it is a good resource. lots of good quality FREE stuff.
