Correlation structure of the Burrell and Cane mixed Poisson model for library loans with aging is presented and illustrated by data from University of Sussex. The approach is compared and contrasted with that originally formulated by Morse and recently reevaluated by Beheshti and Tague. Directions for future investigations are suggested. (Author)

A survey at the University of Port Harcourt (Nigeria) examined faculty attitudes toward returning overdue library books. Results were analyzed using the cluster method of factor analysis, and forgetfulness of library obligation and personalization of resources were identified as the primary factors influencing faculty to retain books. The…

Statistics on book budgets, population served, and collection size of individual public libraries in New York State were correlated with their circulation data to examine efficiency of scale for mid-size libraries. Findings show that circulation increases erratically with increased book budgets and size of population, but consistently with…

Utilizing 11 years of University of Saskatchewan circulation transactions, it is shown that P. M. Morse's Markov model of book use fits approximately 99 percent of data for whole collection and for three subject areas; contrary to his assumptions, one of the model's parameters is time dependent. Thirteen references are included. (EJS)

This study of 50 pairs of popular (written for layman) and technical (designed for those having specialized knowledge in particular discipline) monographs matched by subject, date of publication, and date of acquisition indicates that although technical works circulated more than popular, difference was not statistically significant. Seven…

A theoretical model proposed by Paul Kantor for determining shelf availability for library materials by checking a small sample of items drawn from the checklist against the stacks and circulation records is applied to a working environment, and the following considerations are examined: (1) time required to apply the model to a working library…

This article describes study of the relative effectiveness of classroom faculty and librarians as book selection agents in a small urban commuter college located in Chicago, Illinois. Use of history section of collection, hypotheses tested, data collection and analysis, circulation activity, and comparative data are highlighted. Eight references…

Library circulation records for five years in one Hawaiian elementary school were analyzed to discover patterns according to sex and grade level; identify titles, subjects, and types of books circulated; and determine circulation of Hawaiiana and books about Asia. Bibliography of 129 titles mentioned in text is included. (11 references) (EJS)

Resulting from the Association of Research Libraries' (ARL) 1975 survey on user services, this kit presents documentation on and discusses developments in physical access services--services which facilitate the actual delivery of information sources to the user--including circulation, interlibrary loan, book delivery, and new media services. As…

This report describes a study of the use of science and technology books and journals in an academic library which was conducted to ascertain whether journal use can be predicted by book circulation figures. The study background and significance are discussed, terms are defined, study limitations are considered, and basic assumptions are…

Describes a circulation model for academic research libraries which uses the mixed Poisson model, incorporating ageing of library materials, to predict future use of monographs and to suggest weeding procedures based on frequency of circulation. Longitudinal studies are examined and statistical details are appended. (Author/LRW)
