There is a bookshelf in the CS Projects Lab, EB 2029, where faculty will be putting books, mags, and journals for anyone who wishes to take them.
I'll be putting Wired, PC World, Communications of the ACM, and a few others on the shelves.
On a similar note. You can visit this (http://www.tcfb.com/freetechbooks/index.html) website to download some free books. Check it out.
