Abstract

This article examines the role of subject headings in providing access to information for the Spanish-speaking population of the United States. Such tools for assigning subject headings as Library of Congress Subject Headings (LCSH) and Bilindex are examined and their effectiveness assessed. A pika is made to technical services librarians to go beyond standardized methods of cataloging in order to assure meaningful access for Spanish-speaking patrons.

Abstract

The syndetic structure of subject headings lists, in particular the broader/narrower term references, constitutes a hidden classification that may be converted to an explicit tree structure. Such a structure may be used to examine the hierarchy of LC subject headings (LCSH) and to compare them with that of Library of Congress Classification (LCC). Joseph Galron's compilation, 'Library of Congress Subject Headings in Jewish Studies (1991)', was analyzed for several features relating to the hierarchy of terms, and trees tructures were built for the deepest hierarchies: Jews, Judaism, Hebrew language, and Israel. These were compared with the corresponding LC classes. A hierarchy in LCSH may have more levels than the corresponding schedule in LCC. It is concluded that the conversion of the BT / NT references of subject headings lists into tree structures is a useful tool for examining the correctness of a hierarchy. Display of subject headings in tree-structure format can assist users in grasping the hierarchy of subject headings and in navigating online catalogs

Abstract

An analysis of a sample of 9.442 headings assigned by the LoC to bibliographic records disclosed 2 types of invalid headings: those that were erroneous and those that were obsolete. Each type revealed recurring patterns. Errors and obsolete elements occuring in assigned heading involve MARC coding, terminology in main headings and subdivisions, application of subdivisions, and in mechanical elements such as punctuation and capitalization. Different headings (e.g. personal name, corporate name, topical, etc.) display different patterns as well as predominance of errors and obsoleteness. Although the overall error rate is low, an awareness and understanding of patterns of errors and obsolescnce in subject heading strings should contribute to improvement in subject heading assignment and subject authority control

Abstract

Form and genre headings are used in the cataloging of archives and manuscripts, audiovisual materials and monographic works of fiction. These headings can also be useful in cataloging serial publications. Form and genre headings can describe the physical format of a serial as well as the point of view or other characteristics relating to what the serial is, rather than what it is about. The headings are particularly useful in the description of "general" periodicals. Catalogers must exercise caution in assigning terms which might "label" the publication as outlined in the American Library Association's Statement on Labeling.

Abstract

LCSH is known as such since 1975. It always has created headings to serve the LC collections instead of a theoretical basis. It started to replace cross reference codes by thesaural codes in 1986, in a mechanical fashion. It was in no way transformed into a thesaurus. Its encyclopedic coverage, its pre-coordinate concepts make it substantially distinct, considering that thesauri usually map a restricted field of knowledge and use uniterms. The questions raised are whether the new symbols comply with thesaurus standards and if they are true to one or to several models. Explanations and definitions from other lists of subject headings and thesauri, literature in the field of classification and subject indexing will provide some answers. For instance, see refers from a subject heading not used to another or others used. Exceptionally it will lead from a specific term to a more general one. Some equate a see reference with the equivalence relationship. Such relationships are pointed by USE in LCSH. See also references are made from the broader subject to narrower parts of it and also between associated subjects. They suggest lateral or vertical connexions as well as reciprocal relationships. They serve a coordination purpose for some, lay down a methodical search itinerary for others. Since their inception in the 1950's thesauri have been devised for indexing and retrieving information in the fields of science and technology. Eventually they attended to a number of social sciences and humanities. Research derived from thesauri was voluminous. Numerous guidelines are designed. They did not discriminate between the "hard" sciences and the social sciences. RT relationships are widely but diversely used in numerous controlled vocabularies. LCSH's aim is to achieve a list almost free of RT and SA references. It thus restricts relationships to BT/NT, USE and UF. This raises the question as to whether all fields of knowledge can "fit" in the Procrustean bed of RT/NT, i.e., genus/species relationships. Standard codes were devised. It was soon realized that BT/NT, well suited to the genus/species couple could not signal a whole-part relationship. In LCSH, BT and NT function as reciprocals, the whole-part relationship is taken into account by ISO. It is amply elaborated upon by authors. The part-whole connexion is sometimes studied apart. The decision to replace cross reference codes was an improvement. Relations can now be distinguished through the distinct needs of numerous fields of knowledge are not attended to. Topic inclusion, and topic-subtopic, could provide the missing link where genus/species or whole/part are inadequate. Distinct codes, BT/NT and whole/part, should be provided. Sorting relationships with mechanical means can only lead to confusion.

Abstract

Recognition, by libraries, of the need for improved efficiency and reliability in subject authority control in catalogues led to a study of the feasibility of automatically creating a subject heading validation file by scanning the OLUC. The premises were: that although the file would not be axhaustive, it would contain the majority of frequently used headings; and that the predicted level of accurary in the file would be high. A sample file of Library of Congress assigned subject headings, from the OCLC Subject Headings Corrections database was analyzed. Results showed that: the frequency of use varies inversely with the number of headings at a given rrate of use; a small number of headings with high frequencies of use accounts for the majority of total use, while a large proportion shows very low frequency of use; topical headings account for 2/3 of assigned headings; and error and obsolescence rates are both low and are in inverse relationship to the frequency of heading use. Concludes that an automatically generated subject heading validation file is feasible and could serve various purposes, including: verification of subject heading strings constructed by cataloguers; updating of subject headings in catalogue maintenance; and validation of subject headings during retrospective catalogue conversion

Abstract

Subject headings do not always adequately express the subject content of books and other library materials. Whether due to cataloguer error or inadequacy in the authority list, this deficiency makes it difficult for users to access information. In an attempt to solve this problem, the study evaluated the adequacy of the LoC Subject Headings assigned to the 23 books of Pierre Bourdieu, whose philosophical ideas were judged likely to form a good test of the ability of the subject headings to reflect the ideas proposed by the author. The study examined the subject headings given to 22 books, and their translations into English, Spanish, Portuguese, and German, comprising 88 records in OCLC as of Dec 91. It was found that most of the books received headings not corresponding to their content, as the headings were assigned from the functionalist paradigm. In general, LCSHs ignore the conceptual categories of other paradigms, do not match the current vocabulary used by social scientists, and are ideologically biased

Abstract

Authority records were compared for established headings that are identical in LCSH (18th ed.) and Moving Image Materials (MIM). The Use For, Broader Term, Narrower Term, and Related Term references in the LCSH authority file were compared with their counterparts in MIM, to determine the proportion of duplication existing between them. Fewer that 10% of these reference headings are identical. A qualitative comparison was made of the 'semantic spaces' inhibited by identical headings in different contexts: a general purpose subject access list is compared with a medium specific form and genre access list. It was found that, in many cases, headings that are identical as character strings have markedly differnt meanings in different contexts. The conclusion offered is that, both quantitatively and qualitatively, pairs of identical headings differ sufficiently from each other that the creation of authority records for each usage represents no duplication in any meaningful sense. The striking divergence, in many instances, between semantic spaces poses intellectual questions regarding the differences between the meaning of subjects and of forms and genres
