Most people have. Project Gutenberg (which I also love) gets all the press. I heard about LibriVox from my brother, when he found out that I like audio books.Margret , thank you for the tip on LibriVox. Somehow, I had overlooked that site. I just got Huckleberry Finn to listen to.
Incidentally, there's a free LibriVox app you can get for your smartphone; it will let you listen to the books online or download them to your phone. It will also link to some books that are still in copyright and give you the option to buy, as well as some free books that aren't available on the LibriVox website. I listened to a dramatization (not a reading/dramatization, just a dramatization) of Isaac Asimov's third (I think) Foundation novel that had been done by the BBC and made available for free.
