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)

A survey collected recorded library circulation statistics for 241 four-year liberal arts colleges and universities. While the survey identified several libraries with comparatively high circulation averages, it also indicated that for a great many institutions the per student rate of circulation books remains about the same as it was over 35…

A study to be made with computer-based circulation data of the non-use and use of a large academic library is discussed. A search of the literature reveals that computer-based circulation systems can be, but have not been, utilized to provide data bases for systematic analyses of library users and resources. The data gathered in the circulation…

A study of the reserve materials collection at the Main Library from a usage and cost analysis perspective revealed that 93.7% of all items that circulated could have been circulated an equal number of times through the standard circulation procedure which allows material to be used for seven days. The remaining 6.3% of the material which…

Computer-based circulation systems, it is widely believed, can be utilized to provide data for library use studies. The study described in this report involves using such a data base to analyze aspects of library use and non-use and types of users. Another major objective of this research was the testing of machine-readable circulation data…

The research reported in this paper examined data related to the characteristics of interlibrary loan borrowers, the material borrowed, the question of cost and time it takes to acquire the material, and staff information and procedures. The variables were coded onto computer cards and then tabulated into frequency tables by the computer. There…

Analysis of circulation records for maps at a university library show that borrowers are widely distributed throughout many departments of the university, with heaviest use by graduate students for research purposes. Geographical emphasis is on the local area and aerial photographs and topographic maps are the most popular types. (Author)

A theoretical foundation is provided for a method of identifying those books in a library's stack that determine any given percentage of the current circulation. Basic components and requirements of the technique are described, and the theory is applied in an example that manipulates data from a university library. (Author/MBR)

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)

A method of estimating the number of duplicate copies of books needed based on a computer simulation which takes into account number of copies available, number of loans, total underlying demand, satisfaction level, percentage time on shelf. (LS)

After increasing for a decade, circulation of books at Brooklyn College reached a peak and then declined. A staff member sought circulation data from libraries whose parent institutions were members of the Association of Urban Libraries. These showed a similar phenomenon and a wider sample was sought, including public and private four-year…

Undertaken to determine if the pattern of use of library reserve collections found at other college libraries continues to exist at DePauw, this study found that approximately 40 percent of all the reserve collection items never circulated during the entire semester, and that 33 percent of the collection circulated only one to five times during…

The use of overdue notices or threat of encumbrance (the withholding of students' grades until library books are returned) is a common practice in academic libraries. Yet the effectiveness of such policies has seldom been investigated. This study examined a circulation overdue policy, comparing selected variations in that policy. Three levels of…

The validity of the assumption that those documents which are requested from a University of California (UC) library by the California State University and Colleges (CSUC) campuses through interlibrary loan are the "low use" items, according to the in-house circulation statistics of the lending institution, was tested. This was one of…
