Predicting that a large component of the library of the not so distant future will be an electronic network of file servers where information is stored for access by personal computer workstations in remote locations as well as the library, this paper discusses innovative computer technologies--particularly CD-ROM (Compact Disk-Read Only Memory)…

Discussion of image-based information retrieval systems focuses on indexing. Highlights include computerized information retrieval; multimedia optical systems; optical mass storage and personal computers; and a case study that describes an optical disk system which was developed to preserve, access, and disseminate military documents. (19…

Describes compression methods for components of full-text systems such as text databases on CD-ROM. Topics discussed include storage media; structures for full-text retrieval, including indexes, inverted files, and bitmaps; compression tools; memory requirements during retrieval; and ranking and information retrieval. (Contains 53 references.)…

Describes problems encountered during early attempts at library automation in China, including the slow development of telecommunications systems and the high cost of international online retrieval. The successful use of imported databases on CD-ROM to overcome these problems is discussed, focusing on applications in library technical services and…

Discusses the need for knowledge gateway systems to provide access to scattered information and the use of technologies in gateway building, including artificial intelligence and expert systems, networking, online retrieval systems, optical storage, and natural language processing. The status of four existing gateways is described. (20 references)…

This study examined the effectiveness of a simple browse search strategy and a more complex analytical strategy with 25 high school students, using an electronic full-text encyclopedia. Captured keystrokes and student essays were analyzed for retrieval performance and information application. No significant differences between types of search…

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…

The second of two articles discusses topics relating to the development of CD-ROM technology: (1) new applications; (2) the image of what CD-ROM will become; (3) the properties of information, including timeliness, risk, and the relationship between message and medium; and (4) growth issues such as production, pricing, and user training and…

Describes a microcomputer-based multimedia system that enables videotape presentations to be created by assembling still or moving data, with sound and in color, from a variety of sources. Source media include Macintosh storage of text and graphics, and various types of videotape and disc players. (18 references) (CLB)

Discusses the use of optical disk technology in online searching and compares three versions of the ERIC database currently available on optical disk in terms of hardware requirements, ease of installation, scope and cost of the system, search procedures, displaying and printing results, and documentation and user support. (CLB)

Discusses the extent to which online use of databases is affected by a foreign language barrier. Topics discussed include the effects in western Europe on establishing a uniform information market; database distribution by language; retrieval software; contracts, documentation, and training; and databases that try to overcome the language barrier.…

Discusses factors that should be considered by buyers and producers of databases on CD-ROM (compact disc-read only memory). The advantages and disadvantages of CD-ROM are also discussed and compared with those of magnetic and print media, and market projections are provided. (CLB)

Traces the development of database production and the online industry in Australia, focusing on recent trends, problems and prospects for future online and CD-ROM use. Argues that new pricing arrangements can provide growth in a market fragmented by increases in specialization and government information, and in numbers of vendors, databases, end…

Discusses the human-computer interface as it relates to information technology and retrieval. Principles of interface design are examined, including visual display features and help messages; information retrieval applications are described, including online searching, CD-ROM, online public access catalogs (OPACs), and full-text databases; and…

This review of new developments and products in online services discusses trends in travel related services; full text databases; statistical source databases; an emphasis on regional and international business news; and user friendly systems. (Author/CLB)
