This study compares the three versions of DOBIS (Dartmunder Bibliothekssystem) that are currently running in Canada and the Washington Library Network (WLN) systems in order to determine which one is the most appropriate to replicate in support of the British Columbia Library Network (BCLN). Comparisons of systems costs and operating features, the availability of desired cataloging information, time required to use the systems, and the relative impact of the two systems upon cataloging operations are presented. Figures display the data in detail. An additional report, "A Summary Analysis of the Impact on Cataloguing of DOBIS and WLN," by Ann Turner, Carolyn A. Hoffman, and Shirley Ward, is included. (FM)
