Preservation Information Dissemination: Information relating to preservation needs can be assembled through research efforts, case studies, and technology transfer initiatives. This information must then be readily accessible to those charged with making CRM decisions. Computer based systems capable of multitasking and the manipulation and combination of data layers can be adapted to create powerful preservation data acquisition and retrieval systems. These systems will be capable of accommodating an extensive information base and a variety of data types. Similarly, information storage systems using optical disk technologies can be readily adapted to CRM needs. The skillful utilization of these technologies will place the information necessary to shape cost effective cultural resource management strategies at the rapid disposal of decision makers. While destruction by natural forces or intentional demolition by man are significant threats to the integrity of our cultural heritage, the uninformed action of the well-intentioned preservationist represents the most tragic degradation of historic resources. A well-informed community of preservationists is fundamentally the most cost effective way to achieve resource protection objectives, and efficient information acquisition, processing, and retrieval are the linchpins of sound preservation practices.
