Two methods are presented by which the librarian can forecast book circulation by subject. The shelflist model treats the number of library books as a control variable, while the other defines the dependent variable as the proportion of the shelflist circulated. (FM)

Reports experiments with a term weighting model incorporating relevance information in which it is assumed that index terms are distributed dependently. It is argued that, if high recall searches are required, relevance feedback based on the modified dependence model may be superior to the Boolean search. (Author/VT)

This study develops a three-stage model of the question-answering process and investigates several potential sources of extraneous variability. Discussion includes implications of findings concerning what it means to "use" library materials and services, adverbs used as response category labels, and subject's responses as predictors of…

Reviews meaning and theory of library collections and structure and enumerates ways that data on collections can be organized to reveal underlying global structure (links and connections between collections, parts of collections, and users of collections). Definitions of terms applying to eight models described in text are appended. (53…

Describes the development of a gravity model based upon principles of spatial interaction to predict the circulation of libraries in the Indianapolis-Marion County Public Library (Indiana). The model effectively predicted past circulation figures and was tested by predicting future library circulation, particularly for a new branch library.…

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.…

The potential for using a computerized communication system to facilitate resource sharing in New England has been investigated by the staff of the New England Information Network (NELINET). The central purpose of their research was to determine whether a strategy for load leveling of interlibrary loan (ILL) requests could be implemented online as…

Based on a series of six field experiments conducted from 1978 through 1981 at Northeast Louisiana University's Sandel Library, this report examines user preferences related to library carrel arrangement in the context of personal space theory. A brief review of research on personal space requirements and a description of Sandel Library and its…

Study of New Zealand public library effectiveness duplicates research by Childers and Van House which examined the multiple constituencies model of organizational effectiveness. Librarians, users, and councillors rated performance indicators identified from the literature, and similarities and differences between the two studies are reported. A…

Describes a study that investigated the quality of interlibrary loan services in Canadian public libraries from the library's and the user's perspectives and then compared results. Measures of interlibrary loan performance are reviewed; an alternative conceptualization of service quality is discussed; and SERVQUAL, a measure of service quality, is…

Reports on studies conducted to provide an in-depth picture of online catalog use in three aspects of library research: (1) as part of the reference process; (2) as used by unassisted users; (3) as a step in obtaining documents. The research methodology is offered as a model for surveying other library services or products. (14 references) (KRN)

Describes a user-oriented model for setting priorities for services in a medium-size scientific/technical research library. A survey of the research staffs of three organizations regarding their conception of library priorities is compared with the budgets and opinions of the three library directors. The questionnaire used is included. (Author/JD)

Book condition surveys have been conducted in several large research libraries in the United States to determine the extent of book deterioration in those libraries. This paper outlines the steps for conducting a brittle book survey adapted from more comprehensive surveys to assess the extent of paper brittleness of the book collections in a small…

Describes a circulation model for academic research libraries which uses the mixed Poisson model, incorporating ageing of library materials, to predict future use of monographs and to suggest weeding procedures based on frequency of circulation. Longitudinal studies are examined and statistical details are appended. (Author/LRW)

This paper describes the use of a microcomputer model program to predict library collection growth at Cornell University, particularly in Olin Library, which is Cornell's central research facility. The possible effects of increased online information retrieval and microform or videodisc usage on library storage needs are also briefly discussed. A…
