Describes the findings of the Committee on Preservation of the National Archives and Record Service, which compared the effectiveness of machine readable records and microfilm as storage media for archives. Discussion of the disadvantages of machine readable records focuses primarily on the rapid changes in technology. (4 references) (CLB)

The Library of Congress has embarked on a three-year pilot program in image preservation and retrieval using optical disk technology. Print materials (text, maps, music) will be captured on digital optical disks, and nonprint materials (motion pictures, slides, drawings) on analog optical disks, or videodisks. (EJS)

Six articles provide an overview of map librarianship in the United States and highlight the following areas: microphotography, cartography's photographic revolution; major sources for map acquisitions; preservation (processes, equipment, and supply dealers); map collections in public libraries; and suggestions for improvement in map…

Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

The MARC (Machine-Readable Cataloging) format allows the capability of accessing library catalog records by any piece of information found in the catalog record. A library's MARC database is its most expensive investment in library automation, and the most crucial factor in the success of the library's automation. Intended for librarians or…

The Educational Resources Information Center (ERIC) system, which provides access to a wide variety of information concerned with education, is discussed. The process of acquiring, selecting, retrieving, and disseminating documents is described. (Author/PHR)

Outlines the technological evolution and the use of computers and telecommunications in information transactions and data storage. (CWM)

Discusses five different shifts that characterize the transitional nature of today's libraries and examines the extent to which college students agree in interpreting the term, "library use." Findings suggest that the notion of the library as a "space" is better agreed upon than the notion of the library as a "store" or "service." (Author/AEF)

Describes JSTOR (Journal Storage), a not-for-profit organization located in New York City, established to use digital technology to preserve and make accessible core journal literature. Highlights include publisher participation and license agreements; scanning and optical character recognition; missing information; systems design; project goals;…

Describes the nature of computerized data bases. Provides an activity using a data base and designing a data base. (YP)

Presents a guide for selecting an optional disc system. Highlights include storage hierarchy; standards; data life cycles; security; implementing an optical jukebox system; optimizing the system; performance; quality and reliability; software; cost of online versus near-line; and growing opportunities. Sidebars provide additional information on…

Discusses some technical and nontechnical aspects of using electronic portfolios in the classroom; provides examples from Learning Quest's software for the Macintosh computer. Highlights include selecting student work samples, methods of saving samples on the computer, minimizing storage requirements, media storage devices, and suggestions for…

Discusses accessing online electronic documents at the European Telecommunications Satellite Organization (EUTELSAT). Highlights include off-site paper document storage, the document management system, benefits, the EUTELSAT Standard IBM Access software, implementation, the development process, and future enhancements.

Authors, publishers, libraries, and individual consumers have different, sometimes conflicting, needs for scientific and technical information that are met in varying degrees by different publishing media. A number of print and nonprint formats (full-text journals, synopsis journals, microform, CD-ROM, online, etc.) are compared, and combinations…

Describes an approximate document ranking process that uses a compact array of in-memory, low-precision approximations for document length. Combined with another rule for reducing the memory required by partial similarity accumulators, the approximation heuristic allows the ranking of large document collections using less than one byte of memory…
