Describes the use of microcomputer database management systems to facilitate the instructional uses of learning strategies relating to information processing skills, especially recall. Two learning strategies, cross-classification matrixing and node acquisition and integration, are highlighted. (Author/LRW)

Discusses databases and database management systems and explains how they can be used to organize and provide access to information. Highlights include relational models, database design considerations (particularly normalization), query languages used in programming, screen displays, data integrity and security, and effects of the organizational…

Discusses the results of a survey of commercial CD-ROM databases and compares them with previous annual surveys. Topics discussed include the rapid growth in number of available titles; types of databases; subject areas; hardware requirements; frequency of updates; prices; and CD-ROM's potential as a publishing medium. (seven references) (LRW)

Integrating machine-readable data files and microcomputer software (combined as MRDF) into traditional library and information services by incorporating a MARC format for them into the bibliographic networks will increase access to those materials. Standards for their bibliographic control have been developed and progress is being made in their…

Survey of currently available CD-ROM products discusses: (1) subject orientation; (2) database type; (3) update frequency; (4) price structure; (5) hardware configuration; (6) retrieval software; and (7) publisher/marketer. Several graphs depict data in these areas. (five references) (MES)

Discussion of issues surrounding the microcomputer's capability to download online search results covers types of downloading; scope of downloading; legal issues (copyright and database contract provisions and policies); and effects of downloading (widespread pricing changes, and provision of database subsets by database producers). (MBR)

Discusses the effects of microcomputers on online services and products from the perspectives of the major participants in the online industry--database creators and providers; service or network operators; libraries and information brokers; and end users.
