Describes a computer simulation model developed to provide information on the number of terminals or readers needed in the advent of microfilm or computerized catalogs in libraries. Systems with two to 14 terminals are simulated, and decision variables include average patron waiting time, number of patrons lost, and average terminal utilization.…

Analyzes queueing statistics to determine their utility in predicting catalog usage and the relationships between card and serials catalogs and to pinpoint peak catalog usage. This measurement should provide one factor in a simulation model to accurately predict the number of catalog devices needed for alternative catalog formats. Eight references…

Proposes that the concept of the traditional reference desk as the center of reference services in academic libraries is a tradition that should be examined in light of new technologies and changes in the way people find and use information. An alternative or supplementary model is delineated. (Author/CDD)

Compares, contrasts, and critiques predictions that have been made about the future of research libraries, focusing on the impact of technology on the library's role and users' needs. The discussion includes models for the adaptation of new technologies that may assist in library planning and change. (38 references) (CLB)
