Since the early 1980s the evolution of computer mediated communications (CMC) systems designed to support collaborative work has been characterized by two trends. One is the proliferation of new systems to take advantage of technological changes; the second is the incorporation of functionality into highly specialized or tailored application…

Discussion of users and information retrieval systems highlights a study that investigated the representation of users' knowledge by examining their names for objects and concepts, agreement on names, the Library of Congress Subject Headings representation for similar objects and concepts, and measurement of the similarity between these…

Eleven articles introduce expert systems applications in library and information science, and present design and implementation issues of system development for reference services. Topics covered include knowledge based systems, prototype development, the use of artificial intelligence to remedy current system inadequacies, and an expert system to…

Describes an image storage system for contract documentation in the Engineering Directorate of Thames Water Utilities (England) which uses optical disc storage and a relational database for indexing and retrieval of nearly 500,000 pages in compressed image format, and provides end user access through 7 workstations. Requirements, feasibility…

This paper uses a hypothetical application entitled "VAPORTRAILS" to examine how an integrated application can be used to solve the problems of search and retrieval from a range of qualitatively different databases, and the organization of the resulting information into a personal database resource. In addition, four general classes of databases…

Provides detailed instructions for setting up general purpose CD-ROM workstations using IBM compatible microcomputers and tells how to make CD-ROM disks available to the general user. Use of standardized hardware and software, utility programs, DOS batch files, a shell program, and a hypertext program at the University of Idaho Library are…

Discusses methodological issues in empirical studies of information-related behavior in six specific research areas: information needs and uses; information seeking; relevance judgment; online searching (including online public access catalog, online database, and the Web); human-system interactions; and reference transactions. (Contains 191…

Describes the redesign of a CD-ROM database interface by the Congressional Information Service (CIS) that addressed the needs of novice, casual, and expert searchers in academic libraries. Topics discussed include the user profile, the task profile, redesign goals, interaction style, menu design and implementation, system structure and the search…

This continuation of an earlier article discusses online vendors' responses to users' concerns as well as the future of online services. Maxwell Online, Dialog, Mead Data, Data-Star, and Dow Jones News/Retrieval address user needs, search strategies, databases, document retrieval and display, user interface, and cost and economic issues. (LRW)

This study investigated the usefulness of end user systems to library and information science students. Seventeen volunteers were offered free searching on BRS/After Dark and DIALOG's Knowledge Index. The search itself, postsearch questionnaire, and completed research papers were analyzed for databases used, cost and time online, and precision.…

Highlights the changes that have occurred from 1987-93 in database access systems. Topics addressed include types of databases, including CD-ROMs; enduser interface; database selection; database access management, including library instruction and use of primary literature; economic issues; database users; the search process; and improving…

Describes a study that investigated the effects of cognitive style (field dependent and field independent) and online database search experience (novice and experienced) on undergraduate World Wide Web search performance. Considers user factors to predict search efficiency and discusses implications for Web interface design and user training…

Describes a specialist bibliographic database of literature in the field of artificial intelligence created by the Turing Institute (Glasgow, Scotland) using the BRS/Search information retrieval software. The subscription method for end-users--i.e., annual fee entitles user to unlimited access to database, document provision, and printed awareness…

Discussion of search strategy formulation focuses on a study at the University of North Carolina at Chapel Hill that analyzed how medical students developed and revised search strategies for microbiology database searches. Implications for future research on search behavior, for system interface design, and for end user training are suggested. (16…

This report presents the objectives, methodology, and results of a study which assessed the selection and utilization of four MEDLINE search systems by faculty and medical residents at the George Washington University Medical Center. The four systems, which were provided or sponsored by the Himmelfarb Health Sciences Library, offer a wide range of…
