    Abstract
    The authors conducted a six-week queueing study of public catalogs in the Iowa State University library system. Data gathered are analyzed primarily to determine if routinely gathered library statistics can validly be used to predict catalog usage, to discover the ratio between the usage of the card catalog and the serials catalog, and to pinpoint the time of peak card catalog usage in order to measure more closely the rate of use. This measurement, then, provides one factor in a simulation model that can be constructed to predict accurately the number of devices needed for an alternative catalog format
