Discussion of subject access through classification number searching in online library catalogs highlights the present classification climate, increased potential for classification retrieval, effect of past and present practice on effectiveness of class number access, and proposals for action. Thirty-two sources are given. (EJS)

A review of M.I.T.'s INformation TRansfer EXperiments (Project Intrex). The Intrex system includes an augmented catalog stored inan online interactive computer in combination with full-text storage on microfiche. There are discussions of details of the catalog structure, user experiments, economic studies, and information-system networking.…

Discusses the contemporary antagonism between the information seeker and the highly technological information storage systems. Arguments are concerned with the price, availability, and response time of various retrieval methods, ranging from the card catalog to the computer, in addition to the user's problems with the more complex systems. (JVP)

Describes operational use of on-line field access, a powerful improvement upon search key access to on-line records and a viable alternative to full key word access; and discusses some of the questions considered at Northwestern University Library during a redesign of the technical services modules of the Northwestern On-Line Intergrated System…

Presents MARC database statistics for use in planning and processing files, selection of subsets, and estimating file growth rates. Statistics are provided on record length, field tag occurrence, data element length per field tag, and distribution of records by Dewey Decimal Division and Library of Congress class code. (Author/RAA)

Recommends an expansion of MARC codes for decimal class numbers to enhance automated subject retrieval. Five values for a second indicator and two new subfields are suggested for encoding hierarchical relationships among decimal class numbers. Additional subfields are suggested to enhance retrieval through analysis of synthesized numbers in…

Effect of automation on technical and public services, with emphasis on library and human organizational changes. (Author)

The growth in the size of the Internet has resulted in much effort being spent on indexing its contents. The most popular solutions are created by automatic methods, and although offering impressive coverage, they are disappointing where precision of meaning is required. Alternative services created by human beings arrange and index resources…

This listing of 227 citations includes references to existing book, computer output microfilm, and online catalogs, the cost of conversion, the success of existing systems, Anglo-American Cataloging Rules (AACR 2), and the Preserved Context Indexing System (PRECIS). It is intended to aid libraries in making major decisions on what form their…

This examination of the OCLC serials control sub-system points to positive and negative aspects of the OCLC system as they relate to serials, and evaluates the system's serials cataloging capabilities. While this report assumes a knowledge of the basic operations of OCLC, it describes the system in general, its function in cataloging, and its…

Arguing that inadequacy of subject access in online catalogs lies with the database used as a foundation, this essay discusses the weaknesses of Library of Congress subject cataloging and MARC records, electronic card catalogs, enhancement of data, publisher warnings, Boolean search strategy inadequacies, and changes in the national standard. (EJS)

This selected and annotated list of publications includes those pieces published between 1969 and 1979 which treat various aspects of OCLC. They were chosen on the basis of their historical value, their current relevancy, and the amount of new information they contain. Titles are arranged alphabetically by author. (FM)

Comparison of access through the traditional catalog and online systems focuses on functions of the library card catalog--to provide access to all of author's work including works whereby author is identified in nonidentical ways, and to present to user all editions and translations as representations of a given work. (EJS)

Four artificial intelligence (AI) concepts that have relevance for information retrieval systems are discussed and applied to area of authority control in automated catalogs--pattern recognition, representation, problem solving, learning. Existing automated authority control systems are analyzed using two other AI concepts, augmentation and…

Describes the creation and integration of a microfiche catalog into an online computer system for bibliographic control in a university library. Results from two experimental tests are described which demonstrated the feasibility of the system, and costs and operation times are evaluated. Tables of data are included. (Author/BK)
