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…

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…

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…

Reports on output measures that can give children's librarians additional information to better control collections and make better selection and weeding decisions. Statistical comparisons utilizing circulation data (comparing circulation year to year, circulation to patrons served, circulation to number of materials owned) and availability of…

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)

Describes study of manual and experimental automated circulation systems in a university library in Nigeria. Data were collected for eight circulation activities in order to calculate the direct labor costs of circulating a book on each system. Automated system's book circulation costs were higher although direct labor costs were less. (MBR)

Reviews the literature of government document use from mid-1977 through December 1989. The literature is identified and analyzed in terms of 6 library surveys, 3 citation studies, and 13 user surveys. Research findings indicate that social scientists are the heaviest users of documents. (Author/MAB)
