Two sophisticated--autoregressive integrated moving average (ARIMA), straight-line regression--and two naive--simple average, monthly average--forecasting techniques were used to forecast monthly circulation totals of 34 public libraries. Comparisons of forecasts and actual totals revealed that ARIMA and monthly average methods had smallest mean…

An evaluation of 275 titles of adult individual biography selected at random reveals no essential correlation between a quality estimate and any of several measures of circulation. The titles were evaluated for their quality by determining whether or not each title was found listed in eight reviewing journals, five book selection tools, and five…

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…

Describes methodology for the gathering of useful collection management data and reports results of study which analyzed circulation data and sampled in-library use at a Government Printing Office depository to explore circulation and in-library use frequency distributions, circulation and in-library use, and age of publications used in the…

Circulated library books classified according to academic subject areas and student majors were used to determine relative subject similarities in 40 academic departments. Use of multidimensional scaling to compute similarities in undergraduate and graduate circulation and implications for library collection development and storage are described.…

University of Oklahoma Libraries conducted a cost study of circulation service-desk operations. Using percentages of staff time occupied in particular tasks, pay rates, indirect costs, and overhead, total costs were computed on task-by-task basis. Information served as basis for reorganization of work assignments and revision of staff scheduling.…

Proposes and investigates feasibility of using three new variables in addition to simple activity counts in measuring reference services: (1) user questioning regardless of where activity occurs; (2) treating individual user and question as unit of analysis; and (3) examination of questioning in context of other library use.

Circulation statistics for 198 books randomly selected from nonjuvenile collection at Allerton Public Library were ascertained. Comparison of experimental group (all related catalog entries withdrawn from card catalog) and control group (all catalog entries left intact) showed no statistically significant influence of removal of cards on…

Data gathered in application of Paul Kantor's demand-adjusted shelf availability model to medium-sized academic library indicate significant differences in shelf availability when data are analyzed by last circulation date, acquisition date, and imprint date, and when they are gathered during periods of low and high use. Ten references are cited.…

Tests assumption of Markovity in library circulation data using data obtained from Ohio State University Libraries (1975-78) and Rodda's "An Analysis System for Statistical Analysis of Markov Chains" as test instrument. Implications of Markov properties, constraints of data, and testing are discussed. Explanation of transition frequency…

A number of sample inventories were conducted to measure the effectiveness of the Tattle-Tape book detection systems used in the Moffitt Undergraduate Library and the General Reference Services area of Doe Library, and to establish baseline data for missing materials in four branch libraries (Education-Psychology, Engineering, Environmental…

Circulation time-series data from 50 midwest academic libraries were used to test 110 variants of 8 smoothing forecasting methods. Data and methodologies and illustrations of two recommended methods--the single exponential smoothing method and Brown's one-parameter linear exponential smoothing method--are given. Eight references are cited. (EJS)

Comparison of return rates of materials from Ohio State University Libraries to other home loan studies for academic staff and students indicates that due date may be less important than previously thought, and publicity should be tested as means to encourage students to return materials at earlier date.

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…
