Abstract

The main purpose of the study was to determine if the online catalog can function both as a dictionary and classified catalog without requiring additional time or intellectual effort on the part of the cataloger. A total of 1842 MARC bibliographic records listed in the 370-379 classified section of American Book Publishing Record were studied. These records displayed 2735 subject headings. Of these, 1491 (55%) had a Library of Congress classification number linked to them. An alphabetical and classified index was created using primary subjects and their related classification numbers. While such an index could be a useful browsing device if integrated into an online catalog, creating a bona fide classified catalog would require assigning classification numbers to the secondary subject headings.

Abstract

Reports results of an analysis of 205 randomly selected records from the OCLC OLUC, to test the assumption that online catalogues have greatly improved subject searching capabilities, over card catalogues, by making other fields in the records searchable as subject access points (SAPs). Results showed considerable overlap (duplication) among the SAPs provided by the title, subject heading and classification number fields. On average, little more than 4 unique, unduplicated access points were found per record. Where title and classification number fields do add some access points not provided by subject headings, the increase is less than many librarians might be expected. Suggests that OPACs might outperform catalogues more in precision than in recall by allowing greater discrimination in searching; terms from different fields may be combined; titles offer greater specifity; searches can be limited by date, language or other criteria

Abstract

According to the Calhoun report, library operations that are not digital, that do not result in resources that are remotely accessible, that involve professional human judgement or expertise, or that require conceptual categorization and standardization rather than relevance ranking of keywords, do not fit into its proposed "leadership" strategy. This strategy itself, however, is based on an inappropriate business model - and a misrepresentation of that business model to begin with. The Calhoun report draws unjustified conclusions about the digital age, inflates wishful thinking, fails to make critical distinctions, and disregards (as well as mischaracterizes) an alternative "niche" strategy for research libraries, to promote scholarship (rather than increase "market position"). Its recommendations to eliminate Library of Congress Subject Headings, and to use "fast turnaround" time as the "gold standard" in cataloging, are particularly unjustified, and would have serious negative consequences for the capacity of research libraries to promote scholarly research.

1. Introduction In this paper we address two questions: 1. What is the position of subject indexing in the thinking of the library world after the publication of the Functional Requirements for Bibliographic Records (1998)? 2. Is this position in accordance with the requirements of the users searching for documents about a given subject? Research Shows that searching an a topic (i.e. subject access) is an important, even predominant type of end-user searching of library catalogues and even more so of other bibliographic databases. Between one third and two thirds of all OPAC searches are probably subject searches (Large & Beheshti, 199%). Taking into account different ways in which searching an a topic is implemented in library catalogues (subject headings, classification, keywords only) the percentage may be even higher. For example title word searching may be a substitute for subject searching if no better tools are available. In the light of this it is not surprising that the Functional Requirements for Bibliographic Records (FRBR) (1998) pays attention to subject searching, as well as the Functional Requirements and Numbering of Authority Records (FRANAR) (2003). Also the Statement of International Cataloguing Principles: Final draft of 19 December 2003, which is the result of the first First IFLA Meeting of Experts an an International Cataloguing Code mentiong subject access as a function of cataloguing (Statement, 2003). In this paper we discuss the ways these three documents deal with subjects.

Abstract

The impetus for this essay is the library community's uncertainty regarding the present and future direction of the library catalog in the era of Google and mass digitization projects. The uncertainty is evident at the highest levels. Deanna Marcum, Associate Librarian for Library Services at the Library of Congress (LC), is struck by undergraduate students who favor digital resources over the online library catalog because such resources are available at anytime and from anywhere (Marcum, 2006). She suggests that "the detailed attention that we have been paying to descriptive cataloging may no longer be justified ... retooled catalogers could give more time to authority control, subject analysis, [and] resource identification and evaluation" (Marcum, 2006, 8). In an abrupt about-face, LC terminated series added entries in cataloging records, one of the few subject-rich fields in such records (Cataloging Policy and Support Office, 2006). Mann (2006b) and Schniderman (2006) cite evidence of LC's prevailing viewpoint in favor of simplifying cataloging at the expense of subject cataloging. LC commissioned Karen Calhoun (2006) to prepare a report on "revitalizing" the online library catalog. Calhoun's directive is clear: divert resources from cataloging mass-produced formats (e.g., books) to cataloging the unique primary sources (e.g., archives, special collections, teaching objects, research by-products). She sums up her rationale for such a directive, "The existing local catalog's market position has eroded to the point where there is real concern for its ability to weather the competition for information seekers' attention" (p. 10). At the University of California Libraries (2005), a task force's recommendations parallel those in Calhoun report especially regarding the elimination of subject headings in favor of automatically generated metadata. Contemplating these events prompted me to revisit the glorious past of the online library catalog. For a decade and a half beginning in the early 1980s, the online library catalog was the jewel in the crown when people eagerly queued at its terminals to find information written by the world's experts. I despair how eagerly people now embrace Google because of the suspect provenance of the information Google retrieves. Long ago, we could have added more value to the online library catalog but the only thing we changed was the catalog's medium. Our failure to act back then cost the online catalog the crown. Now that the era of mass digitization has begun, we have a second chance at redesigning the online library catalog, getting it right, coaxing back old users, and attracting new ones. Let's revisit the past, reconsidering missed opportunities, reassessing their merits, combining them with new directions, making bold decisions and acting decisively on them.
