I don't really believe books should be free, but I found this AWESOME site with FREE audiobooks. Mostly it's classics and nonfiction, but I found things I've been wanting to read that I just haven't had time for. (Yes, I really do want to read all six volumes of THE HISTORY OF THE DECLINE AND FALL OF THE ROMAN EMPIRE.) All of the books appear to be in the public domain.
Because it's all done on a volunteer basis, some of the books are not as successful as others. (RAT CATCHER sounds like it's read in an electronic voice, with the reader joining sentences together and putting inflections in all the wrong places.) Pay attention to the starred books - those are usually keepers. I've downloaded more than I should, really.
The best thing about the site, though, is how easy it is to download the mp3 files. All you have to do is click on the book of your choice and then the link for the zip file and voila! you have your audiobook. (Hint: Dickens's OUR MUTUAL FRIEND is read by a wonderful reader.) For someone who can't afford audiobooks and has a ton of classics to read, this is a godsend.
This makes my trip that much more exciting!
