Every Dorling Kindersley Guide has been a great and interesting book... and delightful to have and use, even if you are not traveling to that location, but are only interested in learning more!
The Guides are well organized in a logical and easy to follow manner. They are beautifully illustrated, well developed with accurate information (it is unusual for hotel and restaurant information to be that accurate), have enough history to help the reader understand the people and cultural background, and have a lot of useful travel information and useable maps in the appendixes.
