Ebooks

So I have to pay for some course literature. Concepts of Programming Languages and Java Programming: Advanced Topics. The former seems ok, but the latter seems like a waste of money. It also costs about $92, where the former costs about $66. So what do you do when faced with the forced purchase of ENTERPRISE literature? I was hoping to find a place to download CS ebooks, but none of the trackers I've searched have any of the stuff I need.

With the exception of graphics extensions (OpenGL, DirectX) and rare languages, there's really nothing programming-related you can find in a book that you can't easily find online.  Books are helpful, but not $50 helpful.  Get a torrent or google java tutorial.
