The University of Alaska Southeast Egan Library has been analyzing circulation data for several years using reports from the Sirsi-Dynix ILS and freely available online tag cloud generating tools. Librarians use these tools to produce lists of most highly circulating items and subjects. These lists are used to guide collection development. In 2015, the library purchased a subscription to OCLC’s Collection Evaluation tool. The library does not use any other OCLC Worldshare Management Services. The library uploaded circulation data into OCLC Collection Evaluation and created reports available in that system. This poster session will compare the type of reports generated using locally-created methods with the reports generated using OCLC Collection Evaluation and look how each can contribute to effective collection assessment, collection development, and weeding.
