/sci/ - Science & Math

Hello. I come from r9k, where a polite and helpful anon directed me here to inquire about a certain Google Docs location. s/he says you have many textbooks which may help me with my ballooning student debt problem.

This seems like the most logical board to ask this question. Poorfag here, does anyone know of any sites that have torrents of textbooks? Not just piratebay, but a whole site dedicated to textbooks? I found the books for my classes this fall quarter and they are going to be around 800-900 dollars. It seems with astronomical rising of textbook prices, the only logical thing to do is to put them on the internet. Anyways, any info would be great, thanks.

where can I find math & science textbooks online for free (torrents, pdfs, etc)? I don't care much for solutions...

I'm looking for intro courses, but recent editions, as in 2010. I am needing linear algebra, probability, statistics, and biology. I honestly don't have $400 to shell out for these textbooks.
