An existing experimental document and reference retrieval system operating in batch processing, tape oriented mode was converted to an on-line mode with user interaction. Objectives were faster response time, integration of functions, and system accessibility at user location. Effects on file organization, addressing techniques, file maintenance,…

Response time in large, inverted file document retrieval systems is determined by time required to access files of document identifiers on disk and process a Boolean search request. A specialized computer system has been devised that can perform a complicated sample search involving 70 terms and over 60,000 document references 12 to 60 times…

This paper briefly describes the organization of a "data bank" containing research on communication networks, specifies the kinds of information compiled about various network properties, discusses some specific results of the work done to date, and presents some general conclusions about the overall project and its potential advantages to…

Outlined in this pamphlet are basic activities to teach students flowcharting techniques, logic principles, machine description, various memory storage devices, binary arithmetic, and input/output devices. Data processing principles are reviewed. The course objective is to prepare students for advanced courses in data processing. Course goals,…

A bulk data input processor which is available for the Rapidly Extensible Language (REL) English versions is described. In REL English versions, statements that declare names of data items and their interrelationships normally are lines from a terminal or cards in a batch input stream. These statements provide a convenient means of declaring some…

Describes the National Agricultural Library's microcomputer-based expert system, which is designed to help users obtain answers to simple reference questions. Building of the system and its linking to external programs and systems are explained, and building of a total information system is proposed. Samples of the program are provided. (CDD)

Identifies questions that should be asked, problems that may arise, and sources of information for library media specialists choosing hard disk computer systems. (CLB)

Reviews definitions and the scope, history, technological capabilities, and other significant issues of electronic publishing. Advantages and disadvantages of electronic publishing are compared to those of traditional publishing, and possible future impacts of electronic publishing on books and libraries are considered. (CDD)

This article presents a brief history of the videodisc and describes three major current manifestations of this storage medium--read-only, write-once, erasable. The current status of write-once technology, major corporations involved in the field, potential uses for various types of storage media, and software and market trends are highlighted.…

Describes a product--BiblioFile, Library Corporation's catalog production system--and a service--reproduction of public domain software on CD-ROM for sale to those interested--which revolve around the ultra-high-density storage capacity of CD-ROM discs. Criteria for selecting microcomputers are briefly reviewed. (MBR)

Discusses technological research efforts by the Research and Development Department of the British Library in the areas of videotex, videodisc, and teleconferencing, noting the videotex service known as Prestel and the department's network project, called BLEND (Birmingham and Loughborough Electronic Network Development). (EJS)

Discusses trends in computer technology and their use for library catalogs, noting the concept of bandwidth (describes quantity of information transmitted per given unit of time); computer hardware differences (micros, minis, maxis); distributed processing systems and databases; optical disk storage; networks; transmission media; and terminals.…

Presents a technical description of Radio Shack's TRS-80 microcomputer system. Storage and memory are discussed, as well as limitations of the system and a sample program for coding and scoring true-false questions is given. (RAO)

Presents two storage models and several other associated models for the presentation of multimedia documents. Analysis of these models reveals their capacity to synchronize various temporal scenarios while allowing users simultaneous and secure access to multimedia systems. Discusses theoretical foundations, information processing, multimedia…

This summary of the literature on document image processing from 1988-90 focuses on WORM (write once read many) technology and on rewritable (i.e., erasable) optical discs, and excludes CD-ROM. Highlights include vendors and products, standards, comparisons of storage media, software, legal issues, records management, indexing, and computer…
