Collection mapping - An Evolving Tool for Better Resources and Better Access.

Collection evaluation techniques have evolved as a result of technological changes in libraries but their purpose and benefits have remained the same: the ability to understand the specific strengths and weaknesses of information resources with statistical data as well as impressionistic judgments based on experience and knowledge of the discipline area under consideration. Librarians have adjusted the tools to evaluate the state of information resources in specific subject and format collections according to the technology available. Whatever the tool, the "picture" of resources that results enables libraries to adjust their holdings to better meet their missions, while also enabling us to streamline access to information without being tied to strictly bibliographic tags with subject and discipline gateways. Whatever the tool, however, its usefulness is dependent upon the thoughtful and appropriate application by the practitioner. [ABSTRACT FROM AUTHOR]
