The Bradford distribution is introduced and explained; its ambiguity, and relationship to the Zipf distribution are discussed. The general situation that might yield such a distribution is described and shown to fit the interaction between book users and books available. (Author)

A reduction of the loan period to one week for high use items increased student circulation by 20 percent. (LS)

Out-of-library circulation totals were found to be reliable indicators of in-library use. For predicting in-library use (and thus total use) two methods are cited: simple ratio of out to in, and the regression equation. (4 references) (Author/NH)

Reports the findings of a six-year West Virginia University study that tested the "direct access" debate in its main library after undergoing the transition from closed to open stacks. Circulation, book availability, and search and library-use statistics are provided, and their implications are discussed. (Author/JD)

Library collection weeding criteria based upon unequal distribution of demand require that distribution remain stable over time. A mathematical expression is derived that tests that stability. Verification is not inordinately time consuming and is facilitated by the use of automated circulation systems. (Author/RAA)

At Georgia Tech faculty are provided remote bibliographic access to the library through microfiche copies of the card catalog and remote physical access through a delivery system. (Author/PF)

To examine relationship between strength of book reviews in "Choice" and subsequent circulation of titles reviewed, authors drew sample of reviews from "Choice," ranked reviews according to reviewer's opinion of book, determined frequency of circulation in Purdue General Library, and correlated frequency with strength of…

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…

The findings of statistical surveys taken at Loretto Heights College indicate that a person-oriented approach concerned with psychological factors produces better circulation control at lower cost than the object-oriented approach which is conventional. (Author/JN)

Examines data on circulation and in-house use of academic library collections to assess differences according to use, measurement technique, and time period. The discussion examines differences in current periodical use and other kinds of uses, differences between circulation and in-house use, and the reliability of short sampling periods. (13…

Describes a study that measured the benefits of an automated catalog and automated circulation system from the library user's point of view in terms of the value of time saved. Topics discussed include patterns of use, access time, availability of information, search behaviors, and the effectiveness of the measures used. (seven references)…

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…

Describes survey of 500 academic business libraries undertaken to gather information on practices in acquisition, use, retention, and storage of domestic and foreign corporate annual reports, and policies related to their circulation and cataloging. Options for libraries collecting these materials are proposed. Institutions in subset are listed.…

Describes methodology for analyzing MARC (machine-readable cataloging) records of highly circulating titles to document common characteristics for collection development purposes. Application of the methodology in a university library is discussed, and data are presented on commonality of subject heading, author, language, and imprint date for…

Reports measures of the gains in search time and likelihood of success in known-item searches with the Acorn automated catalog at Vanderbilt University. User time and search success are valued in dollar terms to make the measures meaningful for system design choices. (Author/CLB)
