A guide book is a book for tourists or travelers that provides details about a geographic location, tourist destination, or itinerary. It is the written equivalent of a tour guide. Many travel guides now take the form of travel websites rather than printed books.
It will usually include details such as phone numbers, addresses, prices and reviews of hotels and other lodgings, restaurants, and activities. Maps of varying detail are often included. Sometimes historical and cultural information is also provided. Guide books are generally intended to be used in conjunction with actual travel, although simply enjoying a guide book with little or no intention of visiting may be referred to as "armchair tourism".
