This study to determine the hardware and computing facility costs of establishing and operating a British Columbia Library Network (BCLN) for current members of the B. C. Union Catalogue used empirical data regarding their performance of the DOBIS system and estimates of workload, and compared those data with the costs of obtaining current computer-utility services from the University of Toronto's UTLAS system. Hardware and computing facilities requirements, including teleprocessing network evaluation criteria and software support evaluation criteria, are explored. Request for proposal (RFP) information is provided. (FM)
