Abstract

Libraries using the LCSH can increase the effectiveness of their subject access. This can be accomplished through one of four methods for applying an increased number of headings: the addition of subject headings in situations where none have been supplied by LC; the use of pattern secondary headings; the use of major + minor techniques; and the use of minor + major techniques. Each of these methods will provide additional subject access to supplement that produced by the Library of Congress

Abstract

Investigates the inadequacy of the 10th ed. of LCSH regarding Islamic subject headings and compares it with some of the schemes available in Arabic. Whilst LCSH is not entirely inadequate, in some subjects related to Islam there is room for improvement and expansion. The following subjects are covered in the comparison: Islam as a general heading, Quran, the Prophet Muhammad, Hadith, islamic law, prayer, and Muslim pilgrims and pilgrimages

Abstract

Finding needed environmental information by the library users creates some difficulties. This paper evaluates Library of Congress subject headings related to a broad range of environmental topics. The evaluation is limited to entries found in the subject file of the WLN database. The article also presents recommendations and solutions to improve access to "green information."

Abstract

Since the 1950s the Library of the Université Laval in Quebec has devoted a great deal of effort to its subject headings list, the Répertoire de vedettes-matière (RVM), an adaptation of LCSH. Sources from specialised thesauri such as MeSH and Art and Architecture (AAT) supplement the headings. Provides a brief historical overview of the RVM and describes the methodology for integrating AAT descriptions into RVM

Abstract

Attention is drawn to the inadequacies of the existing classification schemes as pointed out by individuals and groups concerned with classification research. The article is based on an earlier study by the author, which identified and arranged in a filiatory way the main concepts of sociology and determined their relative significance as headings in a classification scheme. The sociology schedule in the DDC was examined on the basis of 9 evaluation criteria, as e.g. arrangement of major categories, provision for main concepts, use of phrased headings instead of individual key terms, and scattering of related concepts in the schedule. It was found that a large number of the main concepts of sociology are either not represented in the schedule or mentioned in the scope note only along with the main headings. A table shows 100 main concepts of sociology arranged and classified within 10 major categories or sections, and their provision in the DDC. The study suggests that the DDC needs serious reconsideration with regard to the main headings/categories provided as class headings, terminology used for the concepts, the filiatory structure adopted, and the representation of the main concepts of sociology

Abstract

In this article, we describe and test a two-stage algorithm based on a lexical collocation technique which maps from the lexical clues contained in a document representation into a controlled vocabulary list of subject headings. Using a collection of 4.626 INSPEC documents, we create a 'dictionary' of associations between the lexical items contained in the titles, authors, and abstracts, and controlled vocabulary subject headings assigned to those records by human indexers using a likelihood ratio statistic as the measure of association. In the deployment stage, we use the dictiony to predict which of the controlled vocabulary subject headings best describe new documents when they are presented to the system. Our evaluation of this algorithm, in which we compare the automatically assigned subject headings to the subject headings assigned to the test documents by human catalogers, shows that we can obtain results comparable to, and consistent with, human cataloging. In effect we have cast this as a classic partial match information retrieval problem. We consider the problem to be one of 'retrieving' (or assigning) the most probably 'relevant' (or correct) controlled vocabulary subject headings to a document based on the clues contained in that document

Abstract

Key problems of subject searches in online public access catalogs are that too much may be retrieved and that the display may be arranged in what appears to be an unintuitive and unhelpful manner. A study was undertaken on one large database to determine how often the display of a subject and its modifications and subdivisions extended over more than two screens and what the results on display would be of compressing geographic subdivisions and other modifications. The study then addressed the question of how often the display of a term and its subdivisions was interrupted by the appearance in the display of inverted headings, phrase headings, and headings with parenthetical qualifiers

Abstract

Examines a method of converting assigned UDC numbers into subject headings. The method consists of 2 phases: a dictionary is created that maps UDC numbers to subject headings; and this dictionary is then mechanically applied to convert the bibliographic databases. Tests 15 different UDC classes and records translation success and problems encountered. Closely examines problems encountered in each part and describes 3 main types of UDC classes: the synthetic; the shallow enumerative; and the deep enumerative. Findings show that the time spent in the first phase is tolerable. Considers the initial question of translatability of the whole UDC in the light of the results

Abstract

Explores the question of whether academic libraries keep up with the changes in the LCSH system. Analysis of the handling of 15 subject headings in 50 academic library catalogues available via the Internet found that libraries are not consistently maintaining subject authority control, or making syndetic references and scope notes in their catalogues. Discusses the results from the perspective of the libraries' performance, performance on the headings overall, performance on references, performance on the type of change made to the headings,a nd performance within 3 widely used onlien catalogue systems (DRA, INNOPAC and NOTIS). Discusses the implications of the findings in relationship to expressions of dissatisfaction with the effectiveness of subject cataloguing expressed by discussion groups on the Internet

Abstract

Subject cataloguing is essential for retrieval of materials from library collections. One third of the collections in Pakistani libraries are in Urdu and other local languages. Most deal with Oriental topics. Subject heading lists, available in English speaking countries, lack suitable headings for Oriental subjects. A comprehensive list of subject headings compiled for Pakistani books written in Arabic scripts is badly needed and should be compiled. Reviews the efforts which have been made so far in this field and compares Oriental and Pakistani subject headings and other facilities in various English and Urdu lists

Abstract

Archivists, like all other perpetrators of catalogs, are grappling with the role of authority control and the nature of authority work. The primary objective of authority work in transitional archival catalogs is to balance the headings management aspect of more traditional authority work with the historical/contextuaI aspect of enhanced authority work. Conformance with the standard requirements of headings management is necessary if archival materials are to collocate with other types of material in integrated catalogs. Techniques for archival headings management are described. Two additional objectives are to avoid duplication of work by sharing the results, and to foster the development of information systems that use the expensive authority work to support access.
