I am a huge fan of Frommer's Day by Day guides and I have previously bought and used the New York, Boston, San Francisco and Rome books. The book gives you trips which you can do over each day, so if you are visiting the place for a day it makes sure that you visit all the main points. It gives you lists of the top attractions to see, restaurants to visit and things to do. There are also lots of pictures so you can see what looks good before you visit it. Also the maps within the book cover help you to find your way around and a seperate pull out map is included. A must have for any traveller!
