This report describes a study which used computer analyses of the center's film booking records for fiscal year 1981 to identify those subject areas in the collection for which holdings did not seem to accurately reflect the clientele's levels of interest, as indicated by their use of the collection. Results identified 60 subject areas which met operationally defined conditions for overuse, and ranked them in order of need for strengthening with new titles. A high denial-to-booking ratio was found in 74 subjects, in which no more than 75 percent of the requests were filled, and 22 subject areas met conditions for underuse. The intended use of this information was to assist management in deciding in which subject areas to concentrate acquisitions and weeding efforts, in order to have the greatest impact on overall collection quality. The appendix includes the PL/I program used in analyzing the use data and the tables generated by running the program. Seven references are listed. (Author/LMM)
