I've always liked Frommer's best for European destinations. Rick Steves' "Mona Winks" is a streamlined guide to major museums and very good. I always cut up books into chapters and staple each, then can easily carry info around in my purse. Steves will replace Mona Winks for you if you cut it up to use! I also like the new Dorling Kindersley Eyewitness Guides---the London and Paris ones are very good. Look for them at Costco. Do sample the books at a bookstore or library. Have fun on your trip.
