This microcomputer-based turnkey system offers databases built by librarians providing information such as use of library, book reviews,…

Three separate articles describe the online union catalog developed and implemented at the University of California to enhance public access. Planning for library automation, development and production of the database, access points to the catalog, the patron interface, standardizing input data, and merging records are discussed. References are…

Redesign of human-computer interface for users of computerized information systems can make substantial difference in training time, performance speed, error rates, and user satisfaction. Information and computer scientists are using controlled psychologically oriented experimentation, and evaluations during system development and active use to…

The model presented identifies three basic needs which must be met in order to increase our understanding of the user interface in computerized information systems: empirical studies of users' attitudes; systematic summaries and critical analyses of these studies; and an interim set of guidelines for user interface design. (EJS)

Offers suggestions for developing interactive language programs for classroom use using a microcomputer, and cites educational principles involved: concern is production of language; children learn language by modeling; computer is motivating factor; and student should not be passive receiver of computer program. A program entitled "Writing…

Provides a method for estimating precision without examining individual database documents, which requires knowledge of only the query or expressed information need and a set of database parameters constant for all queries. Concepts of historic and expected precision are examined, and applications of precision-document graphs are assessed. (36…

Reports results from a study exploring the information retrieval (IR) and types of interactive feedback during mediated IR. Five types of interactive feedback were identified, extending the interactive IR model to include relevance, magnitude, and strategy interactive feedback. Implications for further research investigating the nature and models…

The methodological sensibility that will lead to the consideration of the new forms of cybersociality is advanced. Cybersociality refers to the new expressions of "being together," sharing emotions, and communicating in networked social environments. Social interactions in the wired city of Blacksburg, Virginia are analyzed and three groups of…

Presents factors for librarians to consider when decision-making about information retrieval. Discusses indexing theory; thesauri aids; controlled vocabulary or thesauri to increase access; humans versus machines; automated tools; product evaluations and evaluation criteria; automated classification tools; content server products; and document…

Discusses methodological issues in empirical studies of information-related behavior in six specific research areas: information needs and uses; information seeking; relevance judgment; online searching (including online public access catalog, online database, and the Web); human-system interactions; and reference transactions. (Contains 191…

This book focuses on what it feels like and what it means to spend substantial portions of one's everyday life in the chat rooms, support groups, and virtual communities of cyberspace.
