I'm going to start with a disclaimer - I'm not 100% sure what's going on here.
This is the ACTUAL dummies book, which is not a free book, and one you wouldn't normally associate with being posted free on the internet legally, but it's on a super respected site. I'm not sure if they worked a deal or they're doing something wrong or what. In short, this may or may not be legit, but here you go.

I'll make it sticky in the meantime. If it ever goes away, someone let me know.
