Historic preservation, which started as a grassroots movement, now represents the cutting edge in a cultural revolution focused on "green" architecture and sustainability. This book provides comprehensive coverage of the many facets of historic preservation: the philosophy and history of the movement, the role of government, the documentation and designation of historic properties, sensitive architectural designs and planning, preservation technology, and heritage tourism, plus a survey of architectural styles. An ideal introduction to the field for students, historians, preservationists, property owners, local officials, and community leaders, this thoroughly revised edition addresses new subjects, including heritage tourism and partnering with the environmental community. It also includes updated case studies to reflect the most important historic preservation issues of today; and brings the conversation into the twenty-first century.
