I found a cr4p load of e-books on rapidshare.com. You need to get an account though (inexpensively - couple of Euro) and you can download unlimited stuff. Then Google for a rapidshare explorer / search engine and search for the book you looking for or "stocks" or such like. The search enginge will give you file links to rapidshare. I found about 2 gigs worth of stuff covering all sorts of trading / investing topics.
the file that i am referring to is the one that has all the trading books and is about 2 gigs, ive tried downloading it on several torrent sites but i get the same result, dead links or empty folders named after the books, have you downloaded it successfully ?
