I rethought the "violate copyright laws" assertion: I really don't know. It's been removed from my original post. Who knows... maybe the site is selling copies obtained by used bookstores, where they buy books by the pound, and get what they can out of them. I know the "computers" section of the bulk used bookstore I used to see in LA had a lot of outdated programming books, many still crated up waiting for shelf space. Doesn't seem unreasonable that some of those crates would make their way to India in search of a market.
