Reports on the state of currently available digital storage and retrieval systems and describes in detail one-sided optical videodisc LaserData and the Mnemos system, which stores graphic images on microfiche discs. Video Patsearch, Matrox, Philips Megadoc, DEMAND, and Digital Recording Corporation's optical digital records and future videodisc…

Discusses problems resulting from incompatible computer systems. Outlines how to make interchange of data possible between systems. Concludes that with the popularity of microcomputers increasing, learning how to make information compatible between systems is essential. (BSR)

Introduces this issue, which contains papers from the 1991 Data Compression Conference, and defines data compression. The two primary functions of data compression are described, i.e., storage and communications; types of data using compression technology are discussed; compression methods are explained; and current areas of research are…

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)

American copyright law provides a means of stimulating intellectual development and protecting the ownership interests of the authors of copyrighted works. Over the years, U.S. copyright law has evolved in order to respond to societal and technological changes. Under the copyright statute certain uses of a copyrighted work are permitted under the…

Provides specific information on varying photographic materials and processes to aid archivists and curators in preserving photograph collections. Preservation problems related to major types of silver prints on paper (salt, albumen, collodion, gelatin) and to the silver image (oxidation, silver sulfide) are covered. Twenty references are cited.…

Reviews the state of information technologies involving teletext, viewdata, interactive graphics, videodisc, audio synthesis, and holography, and discusses the current understanding of access schemes and cognitive processing. Sixteen suggested readings and nine references are cited. (FM)

Considers systems for the classification of handwriting features, discusses computer storage of information about handwriting features, and summarizes recent studies that give an idea of the range of forensic handwriting research. (GT)

This document discusses the importance of data-quality and presents three simple steps that can help lay the framework for an over all data-quality strategy. The first step is to ask some rather simple questions, such as: (1) How much data does the organization have, how fast is it creating new data, and how many redundant copies are there?; and…

Description of new applications of digital optical disc storage technologies focuses on CD-ROM (Compact Disc--Read Only Memory); CD-I (Compact Disc--Interactive); and DV-I (Digital Video--Interactive). Features of each technology are described in the context of instructional design and educational technology, and the role of educational research…

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)

Explores the information storage potential of videodiscs through comparisons of several videodisc sytems now on the market or under development. A table shows compared costs and storage capacities for microfiche, floppy discs, and three types of videodisc systems. (SW)

Describes recent attempts to make explicit connections between the indexing process and the use of the index or information retrieval system, particularly the utility-theoretic and automatic indexing models of William Cooper and Stephen Harter. Theory and performance, information storage and retrieval, search stage feedback, and indexing are also…

Discusses library applications of several specific CD-ROM products, including library catalogs, book reviews, databases, encyclopedias, and interactive video programs. Such factors as cost effectiveness, ease of use, and user satisfaction are discussed, and a bibliography of books about CD-ROM is provided. (CLB)
