Book excerpt: Historic preservation, which started as a grassroots movement, now represents the cutting edge in a cultural revolution focused on “green” architecture and sustainability. This is the only book to cover the gamut of preservation issues in layman’s language: 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. It is an ideal introduction to the field for students, historians, preservationists, property owners, local officials, and community leaders. Updated throughout, this revised edition addresses new subjects, including heritage tourism and partnering with the environmental community.
