I do not know where this might go, so here it is posted. I just came across a blog that talks about going to delicious and doing a search for any books that you might want. there is a lot of stuff that is not protected on the download page and you can pick it up there for a really great price. FREE! I think they charge way way too much for this stuff any way. If you go the book store and get a Real book you usually do not even pay near as much and you get to take it home. there is an investment in the making of that book. BUT these digital things have no cost associated with it beyond the compiling and marketing. the knowledge is no more valuable than the bookstore brand. And we usually have the added cost of printing it ourselves if we really want to read it and digest it. So go and make the best deal you can with these Rips.
