My favorite reference book is "Desk Ref", which is the larger fatter version of "Pocket Ref". Obviously everything in it can be looked up online, but I just don't like being tied to having an internet connection. I don't have the greatest memory in the world, and am happy to outsource my knowledge to an outboard secondary brain, so actual physical reference books are quite reassuring to me.
