How about "the pirate bookstore".
As to sharing your own scanned, proofed and formatted version of a book, I would not share it either, other than family and close friends (In my case that's about as many as I have fingers on my left hand [yes, 5]).
A thought just occurred to me ... would it be possible to send that file to the original publisher, or copyright holder, or whoever, and offer it to them so that they can then sell it legitimately? Maybe ask for compensation?
Is that advisable?
