Cultural heritage professionals-museum curators, museum professionals, archivists, and librarians- use their specialized knowledge to prioritize the needs of their collections. Preservation managers and collections care specialists draw from experts in climate control, fire safety, pest management, and more in assessing a collection and its needs. And all the special materials within the collections have their experts too. This revised second edition contains a wide range of topic-specific expertise that comprises both an enduring text for preservation and collections care students, as well as an essential one-stop reference for cultural heritage professionals-particularly those in small- to medium sized organizations where resources are limited and professional help, is not always accessible. In addition to updated and expanded existing content, a new chapter on digital prints has been added to the Media and Material. Also new is Expanded information on disaster planning; A quick guide to good, better, and best preservation practices to help institutions strive to improve their own activities; A comparative terminology guide to assist in greater understanding between LAMs; and two quick references for temperature and relative humidity preferences for a wide range of collection materials.
