Based on the concept that library use measurement should have as its basic starting point the individual patron, a method of data collection and analysis has been developed that explores individual patterns of borrowing over time. The method accounts for the number of visits on which borrowing takes place, number of items borrowed per visit, and…

Reports on research undertaken to develop model for planning and evaluating regional multitype library networks that engage in resource sharing. Identification and interdependence of eight organizational variables (planning, governance, funding, communication and delivery, configuration, administration, evaluation, and success) based upon members'…

Describes a study which investigated plans of Association of Research Libraries members in New England for total automated library systems, whether compatibility of microcomputers with existing or proposed equipment is a factor in microcomputer selection, plans for microcomputer use, and how appropriate microcomputer tasks are identified and…

Four methods were used to forecast monthly circulation totals in 15 midwestern academic libraries: dummy time-series regression, lagged time-series regression, simple average (straight-line forecasting), monthly average (naive forecasting). In tests of forecasting accuracy, dummy regression method and monthly mean method exhibited smallest average…

Describes steps in survey project that supplied information for contemplated merger of two libraries by estimating number of volumes and titles and duplication between John Crerar Library collections and University of Chicago Library science collections. Survey's findings for volume duplication are analyzed by subject groupings and by books and…

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)

Reports results of study measuring stack capacity at seven University of California medical and science libraries. Data collection, size of library collections, sample shelf measurements and volume widths, overall results, differences among libraries, time differences between old and new materials, and stack capacity estimates are highlighted.…

A survey of heads of collection development in 104 academic libraries was conducted to determine usefulness of information sources on curriculum change for selectors and extent of library involvement in planning such changes. Procedures developed at University of New Mexico and other universities are highlighted. Questionnaire is appended. (24…

Discusses issues relating to the reliability, validity, utility, and information value of unobtrusive testing of library reference services; provides suggestions for practical applications of these criteria; applies study findings to library decision making and planning; and identifies topics for further methodological refinement.
