The analysis of the four historic sites featured in this publication - Grosse Ile and the Irish Memorial National Historic Site in Canada, Chaco Culture National Historical Park in the United States, Port Arthur Historic Site in Australia, and Hadrian's Wall World Heritage Site in the United Kingdom - provides valuable insight into the creation and management of heritage values. Each case study articulates how values are identified and assessed by the governing bodies; where (and with whom) the values reside; how the values are implemented into management policies and objectives; and the impact that these decisions have on the sites themselves. This book will be a vital tool for institutions and individuals engaged in the study or practice of site management, conservation planning, and/or historic preservation. Also included is a CD-ROM that contains supplemental management and planning documents created and used by the site-management authorities.
