Fourth installment of a directory published in four parts in "Database" (June and August) and "Online" (July and September) provides descriptions of 12 laserdisk products together with information on the producer, compatibility, type of laserdisk, search and retrieval software, interface with magnetic media, conditions of usage, price, and status.…

The objectives of this project were to assist the National Archives and Records Administration (NARA) in developing a policy for the representation, transfer, access, and preservation of electronic records of permanent value. A lack of attention to the management, retention, and selective preservation of these machine-readable records will result…

Seven experts in system planning offer their views on how optical disk systems will affect library participation in online networks, and discuss opportunities presented by these new products. (CLB)

Reviews requirements for a data archive system and describes storage media alternatives that are currently available. Topics discussed include data storage; data distribution; hierarchical storage architecture, including inline storage, online storage, nearline storage, and offline storage; magnetic disks; optical disks; conventional magnetic…

Examines the current development of computer compact disk storage devices (CD-ROM). Describes the basics of how the CD-ROM operates and identifies educational uses. Lists companies currently providing CD-ROM software and producing CD-ROM players. (MVL)

Discusses the importance of the next article in this issue, which deals with the acceptance of electronic or optical forms of data as evidence during litigation. The collection and storage of data in new formats is described, and the need for technological knowledge for attorneys acting as general counsel to agencies is discussed. (LRW)

Presents guidelines prepared by Department of Justice Management Division staff to provide an understanding of the rules of evidence as they apply to electronically filed records and ensure that appropriate agency procedures are instituted in creating and maintaining such records. Hearsay, authentication, and the laying of a proper foundation are…

Classifies and briefly describes several types of optical storage media available today--read-only and write-once analog disks, read-only and write-once digital disks and erasable disks. The appropriateness of CD-ROM (compact disk read-only memory) for use in libraries of developing nations is discussed in terms of users' information needs and…

This continuation of the previously published four part directory reports information on several additional laserdisk databases and provides updates on some of those included in the original listing. Included in the product descriptions are producers; compatibility; type of laserdisk; software; interface with magnetic media; conditions of usage;…

Explores the use of analog optical disks as a practical, cost effective means of building picture databases. Questions that should be asked to determine whether optical disk is a suitable picture storage alternative for a particular application are identified and three implementation issues--imaging, indexing, and integrating--are discussed. (CLB)

This annotated bibliography contains citations for over 70 recently published journal articles, reports, and monographs on the subject of optical disks. Items are arranged alphabetically by author with annotations plus additional notes where appropriate. (CLB)

This current overview of optical disk technology describes the evolving marketplace for optical products, the use of libraries as test sites for prototype CD-ROM (compact disk read-only-memory) products, CD-ROM developments, new optical technologies, and advances in magnetics. A list of some compact disk manufacturers and a glossary of terms are…

Examines factors which may affect the receptivity of librarians to the use of optical disk technologies, including hardware and software issues, the content of currently available databases, and the integration of optical technologies into existing library services. (CLB)

Recognizing that the fast-developing optical storage technologies provide a new dimension in publishing and information storage, retrieval, and distribution, this report examines the technical characteristics and capabilities of video and optical systems and the implications of this technology. The following aspects of optical disk systems are…

The components and features of ERIC on CD-ROM are discussed. Search techniques and the value of this resource are described. Different systems available are noted. (CW)
