Weyeneth (history, the University of South Carolina-Columbia) charts the changing philosophy of the American preservation movement during the last 50 years. He traces the Historic Charleston Foundation's pathbreaking approach to preservation, from the organization's establishment to its current wide-ranging concern with the conservation of rural spaces in the surrounding region. He argues that the foundation has been a leader in broadening the field of historic preservation to its current scope as a form of urban planning. Includes b&w historical and contemporary photos.
