- An Operations Research Study of the Pacific Northwest Bibliographic Center: Final Report. Taylor, David W. And Others Citations (References) College Libraries Information Centers Information Services Interlibrary Loans Library Cooperation Library Services Operations Research Reports This report describes the operations of the Pacific Northwest Bibliographic Center (PNBC) which is located at the University of Washington's Library in Seattle. The Center's Union Catalog contains bibliographic citations for 1,778,000 different titles held by 45 libraries in the Pacific Northwest. The Union Catalog is supplemented by microfilm files and several book catalogs, as well as the University of Washington Library's card catalog. These resources are estimated to describe and provide locations to approximately 2.75 million different titles. The filing and searching operations of PNBC are described in detail and costed. Flow-charts are provided. The characteristics of requests received, processed and those for which locations were not provided are described. PNBC's success rate in providing locations for requests is 83.11%. Of the requests forwarded by PNBC to potential lending libraries, 83.69% result in materials being delivered to the requesting library. A determination was made of the elapsed times for component elements in the sequence from a library requesting material, through processing within PNBC to the library receiving the material. Processing time within PNBC was found to be 13.01% of the total "turn-around" mean time of 19.75 days, and about 6% of the total mode time of 10.5 days. (Author)
