The A to Z is an absolutely invaluable map for anyone who intends to do any extended travelling in London. Travelers should be aware that this is purely a map. It is not a guidebook. But it is most certainly an amazing map and a valuable resource. The A to Z maps all of London, from the outer edges to the center of the city, in 152 pages. Each of the maps offers a remarkably precise level of detail. It includes streets- everything from major motorways to tiny alleys. The book's cover claims to map over 69,000 streets, and it's easy to believe when you see the level of detail that these maps capture. The maps also include post offices, churches, schools, hospitals, shopping centers, tube and train stations, even walking paths in parks and greens. Streets, hospitals, and neighborhoods are also helpfully indexed in the back. Because the A to Z breaks the London map down into a series of smaller sections, it fits nicely into compact book form, which makes it easy to throw into your bag for a day of sightseeing or travel. For those intending to spend time in central London, one of the most valuable features is a 16-page superscale map of central London, allowing even greater detail, and clearly marking numerous points of historical and general interest. This is an invaluable resource for anyone walking, driving, or traveling in London.
