Stewart Green, Falcon Guides
Rock Climbing Europe is the perfect starting point for Americans on their way to Europe. The book is far from comprehensive, so ensure that your destination is included before laying out $40 or so. If your destination is included, expect explicit, robust, American-style route descriptions (a rarity in European guides) & photo-topos, all prefaced with a good deal of "Lonely Planet"-style traveler information. The book also follows the Falcon Guide system of providing tips on lodging/camping and where to find amenities in the local area. The book is encyclopedic is size, so you may want to xerox the key sections if you're going for a short trip.
