Introduction to use of compact disk technology for storing digital data highlights history, background, and developments; technical features; standardization issues; current CD ROM applications; and the market for CD products. A production diagram, a sampling of CD manufacturers and disk replicators, and performance comparison of three storage…

Survey of recent developments in microcomputer technology, mass-storage technology, and telecommunications technology shows how these new technologies are driving the development of a new generation of information systems. Major changes in the information industry precipitated by arrival of new information systems and telecommunication…

Describes imaging technology, which allows huge numbers of words and illustrations to be reduced to tiny fraction of space required by originals and discusses current applications. Highlights include image processing system at National Archives; use by banks for high-speed check processing; engineering document management systems (EDMS); folder…

This article defines three separate categories of microcomputers--personal, desk-top, multi-user devices--and relates storage capabilities (expandability, floppy disks) to library applications. Highlghts include de facto standards, operating systems, database management systems, applications software, circulation control systems, dumb and…

Discusses various optical disk formats, including 5 1/4 inch and smaller, 12-inch, and 14-inch. Typical applications and factors to be considered in format selection are covered. (MES)

Reviews several noncyclical, nonrepetitive hypotheses that try to predict broad spectrum maturational stages of overall information technology growth. Based on the areas of convergence among the hypotheses, several predictions are offered, and it is suggested that we are at a major transition point entering the third stage of computerized…

Examines the present and future capabilities of microcomputers for personal use, and discusses the requirements for such individualized systems, including software and hardware considerations. A glossary is provided, and 31 references are cited. (FM)

Designed to help the correctional administrator meet external demands for information, this detailed analysis of the demand information problem identifies the sources of requests for and the nature of the information required from correctional institutions and discusses the kinds of analytic capabilities required to satisfy most demand information…

Details distinction between digital and analog data, advantages of analog storage, and optical disc use to store analog data. Configuration and potential of three levels of laser disc systems are explained. Selection of display devices for use with laser disc systems and accessing audio data are addressed. (Continued in next issue.) (EJS)

This report describes approaches to database translation (i.e., transferring data and data definitions from a source, either a database management system (DBMS) or a batch file, to a target DBMS), and recommends a method for representing the data structures of newly-proposed network and relational data models in a form suitable for database…

Emphasizes facets of micrographics (field of information processing concerned with making and use of microforms) which influence reference activity and professional responsibilities of reference librarians. Micropublishing, available micropublications, bibliographic control, information storage and retrieval, and microform equipment are noted.…

Examines two primary roles played by natural language processing in storage and retrieval of information and outlines organization of natural language interface for data retrieval (question-answering system) and approaches being taken to text analysis. Research issues in computational linguistics and interactive knowledge acquisition are…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

Brief discussion of state-of-the-art of modeling complex information systems distinguishes between macrolevel and microlevel modeling of such systems. Network layout and hierarchical system models, simulation, information acquisition and dissemination, databases and information storage, and operating systems are described and assessed. Thirty-four…

Describes applications of new technology to information handling on the basis of two trends--the miniaturization of electronic circuits and the shift from analog to digital modes of communication. Information technologies discussed are microcomputers, word processors, telecommunications, storage technologies, databases, videotex, and teletext.…
