The Video PATSEARCH system consists of a microcomputer with a special keyboard and two display screens which accesses the PATSEARCH database of United States government patents on the Bibliographic Retrieval Services (BRS) search system. The microcomputer retrieves text from BRS and matching graphics from an analog optical videodisc. (Author/JJD)

Presents a theoretical framework for navigation in information retrieval systems and describes a prototype retrieval system that was developed to investigate navigation. The use of a visual interface in a spatial representation scheme is described, and results of a user-based evaluation of the system are reported. User questionnaires are appended.…

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

Discusses ways to locate information on the Internet. Highlights include LISTSERVs; files to download, including text, graphics, software, sounds, and animations through Archie; locating files on a Gopher via Veronica; the World Wide Web; and electronic mail addresses. (LRW)

Describes current developments in microcomputer technology, including CD-ROM, the 80386 microprocessor, and the graphic user interface. It is argued that, as the information handling capacity of microcomputers increases, the microcomputer industry will increasingly market information to end users, and the library will be challenged to provide the…

Reviews the current status of satellite remote sensing data, including problems with efficient storage and rapid retrieval of the data, and appropriate computer graphics to process images. Areas of research concerned with overcoming these problems are described. (16 references) (CLB)

This four-section paper begins with a brief description of videotex and the paths its development has followed during its short lifespan. The second section examines how videotex systems should present and display information, and how such information should be internally organized so that it is maximally useful for the reader/user. The analysis,…

Consumers and producers of educational software must make decisions about what kind of software to buy and create. Both groups must base these decisions on criteria that consider what it is important to learn in our technological era, what is workable, and what is currently practical and cost-effective. Five criteria that are central to these…

Issues concerning the implementation of standard user interfaces for CD-ROMs are discussed, including differing perceptions of the ideal interface, graphical user interfaces, user needs, and the standard protocols. It is suggested users should be able to select from a variety of user interfaces on each CD-ROM. (EA)

This essay discusses technological developments that are likely to have an impact on information science in next few years: microcomputers, satellite telecommunications, graphic information, online developments. Implications for the information profession, implications for information science courses, educational practice in 2001, and information…

Discusses the problem of access in managing image collections and describes a prototype system for the University of California Berkeley which would include the University Art Museum, Architectural Slide Library, Geography Department's Map Library and Lowie Museum of Anthropology photographs. The system combines an online public access catalog…

Discussion of graphical user interfaces for online public access catalogs (OPACs) covers the history of OPACs; OPAC front-end design, including examples from Indiana University and the University of Illinois; and planning and implementation of a user interface. (10 references) (EA)
