This collection of readings examines the interaction of economy, culture, politics, policy and space within the United States and the United Kingdom. For the second edition, more than half of the readings are new and the introduction and section prefaces have been revised. A section on the city and "the new urbanism" has been added, and there is increased emphasis on design, tourism, sustainability and culture.
