This review of the research on subject access to library collections focuses on the problems of and prospects for improved online subject access to library collections. Summaries of the general findings of studies on library catalog use and catalog users and some reasons for the frequent failure of subject searches in library catalogs are followed…

NETPAD is a microcomputer-based system, implemented on a Commodore PET 2001-8, by which a human indexer can input, retrieve, and edit information in order to produce a variety of permuted index displays. The basic unit of the NETPAD system is a subnetwork (a description of a single document) containing a set of concept nodes (author, title, date,…

This annual update of a bibliography that was published as a supplement to the first issue of "Online Review" contains 931 references covering the approximate time period of late 1982 through early 1984. Entries are arranged by author within each of 11 sections. Permuted title and author indexes are included. (EJS)

Provides permuted title and author indexes to the 931-item seventh annual update (July 1984 issue of "Online Review") of a bibliography on online information retrieval which was published as a supplement to the first issue of "Online Review." The approximate time period of late 1982 through early 1984 is covered. (EJS)

This essay focuses on use of the Library of Congress Subject Headings system in online catalogs for the retrieval of information by subject. Among the topics addressed are differences among catalog forms (card, microform, and computer); user interface with different forms of catalog; the types of subject indexes employed in present online…

Discusses future of online information retrieval systems in terms of types of computer hardware expected (noting size, memory, cost, microcomputers, peripherals); software expected; "user friendly" interfaces designed to enable users to search without special training; and new approaches to subject analysis and online searching.…

The trend toward on-line utilization of computers in recent years has included the emergence of computer support systems to fill the information processing needs of individuals engaged in scientific research. In this study, a new approach to document description is applied to the design of a personal information storage and retrieval system,…

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…

A ten-year research study designed a mechanized information system in the information processing field. Special attention was paid to implementation criteria entering into on-line retrieval through man-machine dialog from a remote typewriter or video terminal and four major areas were investigated: search strategies, machine stored indexer aids,…

This 22-paper collection addresses a variety of issues related to representation and transfer of knowledge. Individual papers include an explanation of the usefulness of general scientific models versus case-specific approaches and a discussion of different empirical approaches to the general problem of knowledge representation for information…

Two questions arise in regard to the computer-based humanities reference services: (1) What knowledge, abilities, and attitudes should the information specialist or librarian in the university library have in order to aid users in fully exploiting the innovative humanities information handling processes? (2) To what extent do users in the…
