Ive found a really useful IRC channel for locating just about any book. Its located at irc.undernet.org #bookz. To use simply type @seek or @find , a bunch of windows will pop up, with any results matching your search terms. Then simply copy the filename and paste it back into the #bookz window. This will initiate a p2p transfer of the book (.doc, .pdf, .txt etc). It can also be used for mp3s.
I think I did a pretty poor job of explaining it, but its relatively easy to pick up.
now if only we had a convenient way to read electronic books that didn't cost hundreds of dollars.
