Patron-Driven Acquisitions (PDA) is a new model used for e-book acquisition by academic libraries. A key component of this model is to make records of ebooks available in a library catalog and let actual patron usage decide whether or not an item is purchased. However, there has been a lack of research examining the role of the library catalog as…

This article details an open card sort study administered to undergraduate students, graduate students, and librarians at the University of Colorado at Boulder in order to reveal perceptions of library research guides. The study identifies user group preferences for organization and content of research guides, as well as themes emerging from the…

The contributions in this volume represent a decade of OCLC's user behavior research findings that articulate the need for the design of future library services to be all about the user. Highlights include: (1) People associate the library with books and do not consider the library in relation to online resources or reference services; (2) People…

The University of Westminster began collecting and analyzing vendor usage reports since starting their e-book collections in 2004. They have used the results both to monitor the use of the collections and to calculate basic cost-per-use metrics that have informed decisions on whether to renew particular resources. In 2008, they sought to extend…

The first of two parts, this article discusses concepts of value and establishes a theory of use-oriented value for information and information services. Examines the notion of value in philosophy, economics, and library and information services; explores the connection between value and relevance; and develops models of information use and…

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…

In order to develop guidelines for the selection of journals by the Center for Research Libraries, a study was done of the use made of the Center's Journal Access Services (JAS), which supplies photocopies of journal articles to member institutions from the Center's collections and from the British Library Lending Division (BLLD). Based on a…

Reviews studies of historical and current trends in the library location theory; the relationship between distance and library users and variables, including available transportation, use motivation, and community awareness; and public facility location models such as central place theory and elastic demand. Extensive references, four figures, and…

A sample of library-output statistics measuring circulation, reference, and in-library use was collected from 76 libraries and tested for redundancy, correlation, and variation using time-series analysis to test the Relative Fidelity of Measurement Model (RFM). The 275 sample statistics correlated in an unpredicted pattern. Twenty-three sources…

Library usage study of OCLC network-provided software and services indicates most users make local modifications to standard practices. Findings are discussed in terms of network models for decision making in software use; methodology of software user studies; and diffusion of innovation processes in postimplementation stages of transaction…

Develops a conceptual model which places public library use in the context of a series of interrelated decisions made by consumer about allocating time to various activities based on relative costs and benefits, and tests the model against available data on the characteristics of public library users. Seventeen references are included. (EJS)

Explores the potential impact of imposed query, a new model of information-seeking behavior, on current approaches to library service and system evaluation. Discusses reference service evaluation, user studies, output measures, and relevance as an evaluation tool. Argues that imposed query broadens understanding of the user and of the role that…

This report describes a 1980/81 project concerned with the formulation and validation of a model for determining whether cancellation and/or consolidation of serial subscriptions and holdings should be recommended to maximize the cost-effective use of combined collections and staff resources in the Boston Library Consortium (BLC). The publication…

Through utilization of effective sampling procedures, libraries may obtain substantial savings in terms of data collection costs. A theoretical statistical sampling model is presented and two types of random sampling techniques are empirically compared as to their effectiveness in estimating a library usage parameter. Implications are drawn for…

Discussion of methods for gathering journal use information in academic libraries (for retention decisions) highlights an 8.4-year time-series of weekly library journal pickup data. Use of the autocorrelation function, spectral analysis, and intervention analysis is described.(LRW)
