TRLN funded an initial subscription year (2005-06) to the OCLC product for both individual library and group use. The Task Group will participate in training; learn how to analyze the collections of an individual library, a group of campus libraries, and how to compare collections to an individual library or group of libraries. The group will provide an overview of the capabilities of the service to the Committee on Information Resources, determine how to save and archive reports for future use, and coordinate the TRLN report on the findings.
