Book excerpt: Provides an international history of urban development, from its origins to the industrial revolution. This well established book maintains the high standard of information found in the previous two editions, describing the physical results of some 5000 years of urban activity. It explains and develops the concept of 'unplanned' cities that grow organically, in contrast with 'planned' cities that were shaped in response to urban form determinants. Spread throughout the texts are copious illustrations from a wealth of sources, including cartographic urban records, aerial and other photographs, original drawings and the author's numerous analytical line drawings.
