Since lazyness is a virtue, I doubt anyone will scan a complete book (and OCR it) if they can get it from some russian warez site. Camel3 has over 1000 pages, if anyone is strong enough to scan & OCR every single page and image, they probably better spent their time earning money so they can buy the bookshelf. Believe it or not but most Perl ORA books are worth buying... :) (*checking ORA stock rate*)
