This report addresses the objectives of a national survey of users and non-users of online catalogs (OPAC's) as they apply to MELVYL and its implementation in the University of California (UC) Libraries on nine campuses. These objectives were to collect information to enable libraries to improve implementation of support services for public access…

The trend toward on-line utilization of computers in recent years has included the emergence of computer support systems to fill the information processing needs of individuals engaged in scientific research. In this study, a new approach to document description is applied to the design of a personal information storage and retrieval system,…

A description of the system used by Space Documentation Service (SDS) to disseminate combined and accumulated knowledge, as widely as possible, throughout Europe is given. The RECON network, with the full support of NASA, has gradually been extended so that centers in Member States, may, by installing their own terminals, have direct access to the…

A new computer-assisted instruction (CAI) system for college teaching is being tested in two locations by the MITRE Corporation. The system, called TICCIT (Time-Share Interactive Computer-Controlled Information Television), now interacts with more than 100 students, each moving at his own pace, for four semesters of community college math and…

Investigation of end-user searching at National Library of Medicine reveals that volume of searching is related to convenient placement of terminal; slightly fewer than half of potential searchers search for themselves; practices of pharmacists and pathologists do not differ in important ways; end-user searchers perform simple searches. (86…

Summarizes four options for libraries that want to offer end user searching: end user systems (Bibliographic Retrieval Service's Afterdark, DIALOG's Knowledge Index); front-end microcomputer software (Sci-Mate Searcher, Pro-Search, WILSEARCH); gateway services (EASYNET); and local databases (now available on floppy and compact discs). Advantages…

Reports on the Online Catalog Public Access Project, a survey of users and nonusers in 31 U.S. libraries conducted for the Council on Library Resources. Characteristics of users, tasks, library setting, and system interface that affect user satisfaction are identified. A 25-item bibliography and user questionnaire are appended. (7 references) (EJS)

Discusses impact of three selected command language facilities (positional or free text operations, crossfile searching, term frequency analysis--ZOOM) on the man-system interface in relation to operational online information retrieval (IR). A cognitive IR model, searchers' knowledge structures, and searching with different types of command…

Digital libraries are moving from research and development into commercial use. If they are to realize their full potential, however, the experiences of end users need to be taken into account from the earliest stages of design. Those end users are typically individuals who have no particular skills in information retrieval, and are accessing…

This update covers the approximate time period from mid-1980 through late 1981, contains 640 references, and includes books, state of the art reviews, program descriptions, use studies, periodical articles, and the proceedings of four conferences on information retrieval. (Author/JL)

Presents the background, database, user instructions, design criteria, hardware, and commands of the online catalog system at the University of New Brunswick (Canada) library, as well as self-instructional features of the system. Evaluation of systems use and potential applications are discussed, and sample displays are provided. (RBF)

Outlines the technological evolution and the use of computers and telecommunications in information transactions and data storage. (CWM)

Presents a stratified model of information retrieval interaction that views interaction as a dialog between participants (user and computer) through an interface. Discusses traditional and interaction models, and extension to relevance, user modeling, search term selection, and types of feedback in information retrieval. (AEF)

Describes the development of learning companion systems and their contributions to the class of social learning systems that integrate artificial intelligence agents and use machine learning to tutor and interact with students. Outlines initial social learning projects, their programming languages, and weakness. Future improvements will include…

Describes research and development of the Mercury Electronic Library Project, which was developed at Carnegie Mellon University Libraries to design an advanced retrieval system. Topics discussed include system architecture; security; performance, including automated and manual assessments; enhanced retrieval, including available databases;…
