I was looking for a book tonight on Open GL. I found on Apress site for $35. I then searched to see if it was some place else cheaper and I found this site http://it-ebooks.info/ and it was at no cost? It does not seem to be illegal? I did a search to find out if this was a shady company and nothing came up that I could find. I found the book I was looking for and I was able to download the eBook without a problem. They seem to have 100's of programming eBooks for free? It's not a bit-torrent or anything else that seems to be illegal. How can this be, am I missing something?
