- Abstract
- Form subdivisions have always been an important part of the Library of Congress Subject Headings. However, when the MARC format was developed, no separate subfield code to identify form subdivisions was defined. Form and topical subdivisions were both included within a general subdivision category. In 1995, the USMARC Advisory Group approved a proposal defining subfield v for form subdivisions, and in 1999 the Library of Congress (LC) began identifying form subdivisions with the new code. However, there are millions of older bibliographic records lacking the explicit form subdivision coding. Identifying form subdivisions retrospectively is not a simple task. An algorithmic method was developed to identify form subdivisions coded as general subdivisions. The algorithm was used to identify 2,563 unique form subdivisions or combinations of form subdivisions in OCLC's WorldCat. The algorithm proved to be highly accurate with an error rate estimated to be less than 0.1%. The observed usage of the form subdivisions was highly skewed with the 100 most used form subdivisions or combinations of subdivisions accounting for 90% of the assignments.

- Abstract
- This classified critical bibliography continues the work initiated by Monika Kirtland and Pauline Cochrane, and furthered by Steven Blake Shubert. Kirtland and Cochrane published a bibliography surveying the literature critical of LCSH from 1944-1979 titled "Critical Views of LCSH - Library of Congress Subject Headings, A Bibliographic and Bibliometric Essay." Shubert analyzed another decade of literature in his article titled "Critical Views of LCSH-Ten Years Later: A Bibliographic Essay." This current bibliography compiles the next twelve years of critical literature from 1990-2001. Persistent concerns of the past fifty-seven years include inadequate syndetic structure, currency or bias of the headings, and lack of specificity in the subject heading list. New developments and research are in the areas of subdivisions, mapping, indexer inconsistency, and post-coordination. LCSH must become more flexible and easier to use in order to increase its scalability and interoperability as an online subject searching tool.

- Abstract
- Pauline Cochrane and Monika Kirtland's "Critical views of LCSH-Library of Congress Subject Headings: a bibliographic and bibliometric essay" published in 'Cataloging & classification quarterly 1(1982) S.71-93' has been widely cited as a source for discussion and complaints about LCSH. Cochrane and Kirtland cover the literature from 1944-1979. The present work provides a critique of the Cochrane/Kirtland study and a survey of the literature concerning the LCSHs during the 1980s. The classified bibliography is arranged according to the format of the Cochrane/Kirtland study to facilitate comparison. Criticism of LCSH reiterates the same points over and over again, whether it is sparseness, bias or currency of the subject headings. Significant trends which emerged in the 1980s include an increased emphasis on the use of LCSH as an online searching tool, concern for the syndetic structure of LCSH and the role of subdivisions, as well as repeated calls for the development of coherent standards to ensure LCSH evolves and is applied in a consistent manner

- Abstract
- Over the last ten years, the Servizio Bibliotecario Nazionale (SBN) has become the largest Italian network of bibliographic services. The creation of the SBN Index database and its growth through shared cataloging were the focus of attention during the early phase, and for years, discussion was limited to questions of author cataloging and bibliographic description. Subject cataloging was excluded from the cooperative activity of the member libraries. In 1990 the Working Group on Subject Headings and Classes was established to examine this situation. First, a partial solution was found, to permit the launch of the network itself. This was followed, several years later, by the development of the SBN OPAC and the creation of the file of subject headings and classes in the SBN Index. From an operational perspective, the choice was made to forego managing the subject headings file in accordance with shared cataloging principles, with mixed results. In order for the subject file to have broader coverage and to further encourage cooperative subject cataloging, the SBN Index Development Program, in which the Istituto Centrale per il Catalogo Unico delle Biblioteche Italiane (ICCU) has been engaged for about two years, aims at enriching services of the database and opening up new and diversified types of usage. Almost simultaneously the Biblioteca Nazionale Centrale di Firenze (BNCF) initiated a feasibility study on the revision of the Soggettario delle biblioteche italiane (List of Subject Headings in Italian Libraries) for the catalogs of Italian libraries. Both the BNCF and the ICCU share the goal of building a new, consistent vocabulary for documentation of subject matter.

- Abstract
- A thourough understanding of current subject cataloging practice, especially Library of Congress practice, will assist librarians in making the best use of new and emerging technology to ease the task of constructing subject headings. To gain insight into the most current subject cataloging practices at the Library of Congress, a random sample of one thousand bibliographic records with one or more 6XX fields and Library of Congress card numbers assigned from 1988 to the present was drawn from the BOOKSM database. Library of Congress catalogers rely heavily on the system of free-floating subdivisions in the process of constructing subject headings. Attempts to improve the subject cataloging process must take into account this fundamental characteristic of the Library of Congress subject headings system

- Abstract
- The LCSH system is still an important part of the future for subject access to catalogues of bibliographic records. The British Library has decided to reinstate LCSH to records created for the BNB, because of the economic necessity of cooperation and because it provides an available common standard. Outlines development plans for the LCSH, and the British Library's involvement through its participation in the Subject Authorities Cooperative programme. It will also be involved in: training in the application of LCSH, and indexing of works of literature and fiction. The cooperative trend is now towards the creation of an international subject authority database

- Abstract
- Moving to a fully faceted syntax would resolve three problems facing Library of Congress Subject Headings (LCSH): 1. Inconsistent syntax rules; 2. Inability to create headings that are coextensive with the topic of a work; and 3. Lack of effective displays for long lists of subdivisions under a single subject heading in OPACs and similar electronic displays. The authors advocate a fully faceted syntax using the facets of a modern faceted library classification (The Bliss Bibliographic Classification, 2d ed.). They demonstrate how this might be accomplished so as to integrate the new syntax with existing headings.

- Abstract
- In 1986 Libraries Unlimited published Cochrane's book, Improving LCSH for Use in Online Catalogs; Exercises for Self-Help with a Selection of Background Readings. This was preceded in 1981 by an ERIC publication (ED 208 900) by Cochrane, with Monika Kirtland Bibliographic and Bibliometric Essay which documented critical views of LCSH and an analysis of vocabulary control in LCSH (parts of which were published in Cataloging & Classification Quarterly' 1(2/3) (1982), 71-94). Three features of LCSH will be re-examined to check on progress since the time of these earlier publications: notes, structure of relationships between headings in the list, and links between Library of Congress classification numbers and LCSH or other vocabularies

- Abstract
- Authority control of Spanish-language subject headings is described, with a special focus on Mexico. Efforts currently underway in Colombia, Chile, Spain and Mexico, although they share the same language, are somewhat lacking in standardization and cooperation among countries. In the absence of a national authority for bibliographic control in Mexico, a group of university libraries has initiated a cooperative project to build in the near future a national file of Spanish subject headings for the Social Sciences. The project, based upon the experience and rich collections of El Colegio de Mexico, has attracted support from the U.S. Library of Congress and is being partially financed by the U.S.-Mexican Fund for Culture (sponsored by the Rockefeller and Bancomer Foundations). The paper mentions some of the difficulties found in translating LCSH, which is the main resource for the project. These difficulties can include semantics, syndetic structure, or pragmatic problems; most have been solved by supplementing the LCSH with Spanish-language subject heading lists or thesauri
