This analysis of the circulation records of books added to a psychiatric library from July 1983 through May 1985 reports the total number of books circulated, their number and percentage in specific subject areas, missing titles, and usage by in-house and off-site borrowers. Implications for future collection development are explained. (Author/EM)

Storage and financial considerations prompted a reshelving study of 300 scientific review titles which found that about half of all titles at Pennsylvania State University were used at least once and that periodicals were used more often than monograph series. As a result, periodical titles were incorporated into the journal collection and series…

Discusses the need for statistics for librarians to measure the performance, use, and value of electronic scholarly journals to make the best purchasing decisions for their institutions. Reports on two reporting mechanisms, one of which uses the library's log files, and describes other current projects to determine usage measures. (LRW)

Describes a study conducted at Columbia-Greene Community College's library to determine whether a book's previous non-use is indicative of future non-use; whether books are progressively less likely to be used with time; the circulation costs of weeding previously unused books; and the circulation rates of old and new books. (DMM)

Reviews survey responses from 127 nonmedical academic libraries in Nebraska, Iowa, and Kansas regarding their vertical files (e.g., acquisitions, weeding, size, nature, collection management, frequency of use, maintenance of statistics, types of users, circulation, and security), reporting that 109 had vertical files, with most emphasizing topics…

Describes two use studies of the microforms collection at the University of North Carolina at Chapel Hill, one conducted in 1982 and the other in 1987. Collection profiles are presented, use study methodology is discussed, and results of the two studies are analyzed and compared. (Five references) (LRW)

Discusses the concept of information value and presents major findings of user studies and collection evaluations. A case study describing the implementation of networks for information in the areas of biomedicine and agronomy in Brazil in the late 1960s is presented. (35 references) (MES)

This study examined circulation and inhouse use of 13,029 randomly selected volumes--both serials and monographs in all subject areas--in a university library over a 7-year period. Results challenged inference of internal use from circulation figures and the appropriateness of weeding based on lack of circulation alone. A 26-item chronological…

To improve its service, the Offa (Nigeria) township library conducted a user study. The investigation found that 51% of users were students ages 19 and below and that 78% were males. Most users wanted extended hours, improved newspaper collections, more accurate shelving, and a consistent lending policy for all materials and users. (PEN)

Proposes a model for technical journal deselection based on the Bradford law of distribution. The model's operational prescriptives, characteristics of the Bradford distribution in the field of pediatrics, and relevance to collection management are discussed. (42 references) (KRN)

An auxiliary study of the direct observation method for counting periodical usage in Evans Library at Texas A&M University found that student observations contain substantial error and that aggregation problems and cost issues are fundamental constraints to this method. Concludes direct observation may be useful in calibrating the results of…

Presents preliminary results of Clearwater Public Library's study of the usefulness of "Output Measures for Public Libraries" as an indicator of reference performance, and the impact of collection development choices on reference output measures. Data on turnover rate, in-library use, reference fill rate, and reference transactions per…

Examines the short-term effects of online availability on the use of print chemistry journals based on a study at Duke University Chemistry Library. Discusses results that showed a diminished use of the print collection and considers implications for collection management in scientific and technical libraries. (Author/LRW)

Discussion of methods for gathering journal use information in academic libraries (for retention decisions) highlights an 8.4-year time-series of weekly library journal pickup data. Use of the autocorrelation function, spectral analysis, and intervention analysis is described.(LRW)

An investigation of books reviewed (1989-95) in Choice Reviews, the CD-ROM version of Choice, determined all titles mentioned (n44,950) were received or purchased by California State University Dominguez Hills and other academic libraries in the Online Union Catalog (OLUC). Findings were further tested to see how they could be incorporated into an…
