InformIT: FREE Safari Library Pass
“For three days gain unlimited access to thousands of books and video from leading technology publishers, including Addison-Wesley, Cisco Press, Exam Cram, IBM Press, Prentice Hall, Que, and Sams Publishing. For something to read over the holidays.” Be careful however, they enroll you as a paid subscriber if you don’t cancel.
If you don’t know about Safari, it is worth checking out. I’ve often considered a subscription for me.
