Includes a report on a use study of the Excerpta Medica system. (PF)

Describes a study that examined whether increased usage of computer based information systems (CBIS) results in improved end-user satisfaction. The results indicate that both the frequency of CBIS use and the proportion of total time spent using CBIS are positively correlated with end-user satisfaction. The implications for designing measures of…

Examines organizational information management and the notion of information richness--that phenomena by which certain individuals are better able to acquire, process, and utilize information than others. Based on an analysis of research findings, some tentative hypotheses relating management and organizational information richness are suggested…

The traditional concern with relevance or nonrelevance of unexamined documents is misplaced, and traditional measures of effectiveness should be replaced by estimates of direct utility of examined documents. (Author)

Analyzes the half-life of book use through analysis of over 10,000 regional and statewide interlibrary loan requests. Correcting for the growth of the literature, this study indicated that the half-lives of monographs may increase from lower to higher levels of the hierarchy in a library network. (CWM)

Presents results from study of mathematical models (Cobb-Douglas model, mixture of Poissons, inverse effects of distance, weighted entropy) relating to usage of information systems, and notes papers developed during study which provide three types of analysis--literature reviews, analytical studies, and tests of models. Six references are…

This study used multiple regression analysis to relate computer user satisfaction to communication monitor (CM) variables. Results indicate the variables of user expectations, manufacturers, and vendors are most significant in affecting overall satisfaction, whereas number of systems represented and not using communication monitors have least…

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 framework for analyzing the value of information, information products, and services from the viewpoint of information use, and analyzes the practical values of different types of information to study the problems involved in assessing their value-in-use and exchange value. Existing research studies are analyzed using this approach.…

Presents the state-of-the-art of information systems monitoring, addressing historical and current approaches and manual and automated techniques; develops the concept of automated monitoring into a well-defined methodology; formulates methodologies/techniques/theoretical foundations for analyzing monitored data; and discusses computer based…

The U.S. Department of Energy (DOE) software research and development project described explores information seeking behavior of end-user energy experts and develops software offering tutorials on front-end use of DOE/RECON databases and active help in performing online searches. Software development is described and results of prototype testing…

Summarizes the literature on users studies from the perspective that variation in type of search may be considered central to providing a rational explanation and justification of the variations in resource allocation in different types of libraries. (CWM)

This general exposition of information consolidation and primer on information consolidation processes defines information consolidation; discusses the concept's evolution; summarizes its objectives, audiences, value, and benefits; discusses information consolidation processes including selection, evaluation, analysis, synthesis, restructuring,…

Reports on a study of how 13 chief executives in the Canadian publishing and telecommunications industries scan their environments for information and use it in decision making. Critical incidents of information use were analyzed according to their environmental sectors, information sources, and their use in decision making. (Contains 27…

Presents a performance analysis of Egyptian National Scientific and Technical Information Network's retrospective database search service. Statistics regarding service demand, trends, characteristics of searches, search results, U.S. database usage, service turn-around time, and costs are tabulated to profile the evolution and performance of a…
