Describes document image management systems that are used for optical storage to facilitate information retrieval. Document image management applications are described, considerations in evaluating system features and functions are presented, and criteria for evaluating vendors of document image management systems are suggested. (two references)…

The deterioration of printed materials is a problem which is plaguing libraries worldwide. Preservation of these millions of volumes is a daunting task--many of the materials are so brittle that the lightest touch may damage them irrevocably. This paper explores the issues of maintaining preservation efficiency without infringing upon copyright…

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…

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…

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.…

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)

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…

Examines and explains Anglo American Cataloging Rules, 2d edition, chapter 9, and ALA Committee on Cataloging: Description and Access for catalogers not familiar with microcomputers. Seven full descriptive cataloging examples of microcomputer software using these guidelines are included. (Author/CDD)

Discusses the following microcomputer storage devices: floppy discs, cassette tapes, and cartridge drives; and notes the potential of magnetic bubble and charge coupled device memories. (RAO)

Expert operative information is a prerequisite for any form of surgical training. However, the shortening of working hours has reduced surgical training time and learning opportunities. As a potential solution to this problem, multimedia programs have been designed to provide computer-based assistance to surgical trainees outside of the operating…

This publication introduces electronic document imaging systems and provides guidance for local governments in New York in deciding whether such systems should be adopted for their own records and information management purposes. It advises local governments on how to develop plans for using such technology by discussing its advantages and…

The rapid growth and distribution of scholarly research in the middle and late twentieth century, the limited supply of old books and other paper-based materials, and the deterioration of items printed on acidic paper since the mid-1800s have meant that many libraries lack suitable copies of printed sources that their users would like to read. For…

This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

The Air Force has developed a data bank which classifies job descriptions into occupational clusters. A retrieval system, also recently developed computes and publishes a consolidated description of the work being performed by any group which can be defined in terms of the background information. Other retrieval programs are available which enable…
