Svenonius, Elaine – Library Resources and Technical Services, 1983
Six uses of classification in online retrieval systems are envisioned--to improve recall and precision; to conceptualize meaning of vague search terms; to provide structure for browsing; to provide framework for retrieval of nonbibliographic information; to collocate citations; and to achieve compatibility of retrieval languages. Seven sources are…

Lawrence, Gary S. – Library Resources and Technical Services, 1985
Describes various ways in which software systems for online catalogs can be designed to enhance subject access. Highlights include what to search (subject headings, titles, notes, authority-file records, classification numbers, and associated text); truncation and stemming; spelling correction; search strategies (headings, keywords, Boolean…

Madison, Dilys E.; Galejs, John E. – Library Resources and Technical Services, 1971
After a brief description of the Micrographic Catalog Retrieval System (MCRS) and its use in card production, searching procedures are outlined along with statistical data. The experience has demonstrated that the use of MCRS can mean a saving of staff time and more rapid retrieval of LC cataloging copy for current books. (6 references) (Author/NH)

Hudson, Judith A. – Library Resources and Technical Services, 1970
Keyword searches in title statement and subject headings retrieved more relevant references than search by LC or Dewey class numbers or by scanning the Dewey class numbers for area codes. An analysis of false drops was made to determine how the search strategy could be improved. (Author/NH)

Sanders, Thomas R. – Library Resources and Technical Services, 1987
Reviews a wide range of retrieval problems that arose with the implementation of an online catalog in an academic library, especially the problem of retrieving uniform titles coded as authors. The need for changes in the underlying format of coding uniform titles as a universal solution is discussed. (Author/CLB)

Burger, Robert H. – Library Resources and Technical Services, 1984
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…

Lipow, Anne Grodzins – Library Resources and Technical Services, 1983
This overview of the current capabilities of subject access in online public catalogs discusses keyword searching versus subject cataloging, users' views of the online catalog, and user-friendly versus user-hostile systems. Existing online catalogs in public and academic libraries are cited as examples. (EJS)

Mandel, Carol A. – Library Resources and Technical Services, 1985
This paper analyzes proposals for augmenting library bibliographic records for improved subject searching in online catalogs by providing access to parts of books. Arguments for and against adding book content indexing, possible fields for enrichment, and feasibility of 11 alternatives for providing such information are presented. Twenty-two…
