This feasibility study was conducted to collect financial, operational, and other data concerning the alternatives of continuing with the University of Toronto Library Automation System (UTLAS), the present supplier of catalog support to the British Columbia Union Catalogue (BCUC) participating libraries, or of replicating the Washington Library Network (WLN) system. Specifically, the study examined the economic feasibility of replicating the WLN system; produced a comparative feature analysis of WLN and UTLAS; produced cost projections for both systems; provided comprehensive data on the best systems for meeting anticipated needs for support of other functions including acquisitions, serials, circulation, and public access; provided recommendations on the alternatives; and provided recommendations on the next steps to be considered. Tables display the data gathered. An additional paper, "BCUC Governance and Management: A Background Paper for the BCUC Replication Study," by Paul E. Baldwin, is included. (Author/FM)
