Not sure if anyone's heard about it yet. I think there might have been a thread at .net.
Anyways, Project Gutenberg is a project where they collect books whose copyright has expired. You can download the ebooks (and sometimes the audiobooks) for free.
I myself recently downloaded a bunch of stuff including Aesop's Fables, alot of Mythology (greek, roman, norse) and alot of Jack London's works. I also downloaded Bram Stroker's Dracula.
Check it out, it's worth a shot.
