At one point or another, I think I've bought every guide book to WDW in print! The ones I choose to keep buying are the Unofficial Guide (every year, whether I'm planning a trip or not!) and the Passporter (for specific trip planning). DS 8 likes the Birnbaum's For Kids, By Kids as well. Birnbaum's is nice for a quicker, more "surface-facts" treatment of WDW, but I love the in-depth information of the other two.
