Abstract

The nature of a library's collections determines what kind of subject access to provide to those collections. The collections of the Cleveland Public Library serve both the recreational and research needs of a large urban population. The Cleveland Public Library uses Library of Congress Subject Headings to describe its collections. A study of subject searches entered by library patrons over the course of one week reveals several patterns among the types of subject headings used most frequently, reflecting the characteristics of the population served. Other topics discussed include subject access to fiction, juvenileliterature, and specialized collections

Abstract

The impetus for a large-scale study on subject heading understanding was a recommendation of the Library of Congress (LC) Subject Subdivisions Conference that suggested standardizing the order of subject subdivisions for the purpose of simplifying subject cataloging. This paper focuses on unexpected large-scale study findings about multiple meanings for subdivided subject headings and the effects that changes of meaning for different orders of subdivisions had on the meanings that end users and librarians provided to subdivided subject headings. Findings about changes of meaning in subdivided subject headings did not dissuade the authors regarding their recommendation that the library community adopt a standard order of subdivisions. The authors also give suggestions for additional studies of subject heading understanding that build on this one.

Abstract

Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

Abstract

Claims that there is no clear plan, comprehensive philosophy, or macro approach to the revision of Library of Congress Subject Headings. Having missed a great opportunity in the mid-1980s to develop a subject analog of AACR2, LC is now in a period of decline. Discusses alternatives to LC subject access such as PRECIS and keyword searching. Urges LC to halt and reverse the decline by bold, decisive action in the 1990s

Abstract

Considers the future of LCSH and whether their viability can be maintained through a written standardization code. Until there is an online substitute for LC subject headings which has been tested on a large scale over a period of time, a successor to the present combination of LC's controlled vocabulary headings plus computerized techniques such as keyword searching is unlikely to emerge

Rez. in: KO 38(2011) no.4, S.360-361 (M.P. Satija): "The 20th edition of the celebrated Sears List (1sted.1923) published in June 2010 sets a new cycle of three year revision. Earlier it was three and a half years to synchronize with the publication of the new edition of the Abridged Dewey revised after every seven years. In the days of constantly updated WebDewey, it is no more a constraint. For the first time Sears List has been released simultaneously in online database format accessible to licensed subscribers. Responding to the environmental changes the basic edition is the online one whose content is designed in MARC authority. Print edition is now a derivative of the MARC data. The editors keep tabs on the changing information seeking behavior of users and how OPACs are accessed; yet the editors or the publishers never discuss the mechanisms of designing a new edition. The new edition features more than 300 new subject headings suggested by librarians from different types of libraries, vendors of bibliographic records, indexers and subject specialists at the H.W. Wilson Company. Every new edition incorporates advances in vocabulary control, changing approaches of library users for subject access and even in the worldwide use of the English language. Each edition of the Sears List strengthens and continues the policies and consolidates the reforms that began with the 15th edition (1994). It is indeed an era of innovations in Sears. The latest knowledge from information science and information seeking behavior has been deployed to modernize the internal structure and grammar of the Sears List. Continuing adaptation constitutes the key to its success and popularity in the shifting sands of the information-seeking behavior of users. But the List is still a living manifestation of the principles of subject cataloguing put forth by C.A. Cutter (1837-1903).
. . . To summarize, as usual the List continues to provide complete guidance for the subject cataloguers for the maintenance of catalogues, for addition of new headings, and revision of the old ones. Its Introduction is clear and well illustrated, so much so that not only it is an illustrated operational manual to the Sears but also a concise textbook to teach principles and theory of the subject headings. Due to its affordable price and portability it is used to teach basics of subject headings in first year of Knowledge Organization courses. It also acts as an excellent and easy index to the DDC (Weihs 2004). The new edition should be welcome both for subject cataloguers and for teachers of subject cataloguing work."

Abstract

LCSH are increasingly seen as 'the' English language controlled vocabulary, despite their lack of a theoretical foundation, and their evident US bias. In mapping exercises between national subject heading lists, and in exercises in digital resource organization and management, LCSH are often chosen because of the lack of any other widely accepted English language standard for subject cataloguing. It is therefore important that the basic nature of LCSH, their advantages, and their limitations, are well understood both by LIS practitioners and those in the wider information community. Information professionals who attended library school before 1995 - and many more recent library school graduates - are unlikely to have had a formal introduction to LCSH. Paraprofessionals who undertake cataloguing are similarly unlikely to have enjoyed an induction to the broad principles of LCSH. There is currently no compact guide to LCSH written from a UK viewpoint, and this eminently practical text fills that gap. It features topics including: background and history of LCSH; subject heading lists; structure and display in LCSH; form of entry; application of LCSH; document analysis; main headings; topical, geographical and free-floating sub-divisions; building compound headings; name headings; headings for literature, art, music, history and law; and, LCSH in the online environment. There is a strong emphasis throughout on worked examples and practical exercises in the application of the scheme, and a full glossary of terms is supplied. No prior knowledge or experience of subject cataloguing is assumed. This is an indispensable guide to LCSH for practitioners and students alike from a well-known and popular author.

Rez. in: KO 36(2009) nos.2/3, S.180-181 (N.K. Swain): " ... The User's Guide will undoubtedly be of great help to practitioners and tutors, as each chapter includes a summary and exercises. The purpose suggested by the title is fulfilled, serving as a companion to the 19th edition of the Sears List. It is designed a a manual for beginners who will realize the importance of vocabulary control and subject analysis, and start to comprehend the structure and organization of the Sears List as well as the methods and techniques to locate, specify, and construct subject headings. The book, however, lacks a good number of examples for practice. The emphasis seems to have been put more on the theoretical than the practical aspects. Despite this criticism, I unreservedly value the authors' efforts. At the same time, I can't help but wonder if the book will have wide access as the place of publication, the cost and the availability will especially affect the users in developing countries. The User's Guide will be a valuable tool to technical services librarians, subject catalogers, students and teachers of library and information science. It is intended for college and university libraries in general, but more particularly for library schools. The authors produced a work of high quality that stands out in its category.

A study group representing four European national libraries (the Swiss National Library, Die Deutsche Bibliothek, the Bibliothèque nationale de France and The British Library) recently conducted a study on the possibility of establishing multilingual thesaural links between the headings in the LCSH authority file and the authority files of the German indexing system SWD/RSWK and the French indexing system RAMEAU. The study demonstrated a high level of correspondence in main headings, but also revealed a number of issues requiring further investigation. The study group's findings led to recommendations on the scope for the development of a prototype system for linking the three Subject Heading Languages (SHLs) in the databases of the four institutions

Abstract

An understanding of the workings of Library of Congress Subject Headings (LCSH) is one of the most valuable conceptual tools a researcher can have. The subject heading system is by no means obvious or self-evident, however; it must be taught, explained, and exemplified by librarians. Several points must be covered explicitly. The cross-reference notation of UF, BT, RT, SA, and NT has to be explained; the importance of choosing the most specific heading available, rather than a general term, must also be emphasized. There are four ways to find the most specific LCSH terms for a particular topic; two of them come from using the red books, two from using the online catalog itself. All four ways are important; none is obvious. Each must be taught

Abstract

The syntactic and semantic consistency of the subject headings of Library of Congress is a matter of concern to cataloguers who must use appropriate terminologies to describe library materials undergoing processing. This paper looks at the structure of these headings by analyzing comparatively the syntactic types that make up the structures as listed in Literature and Librarianship on pages 3075 to 3085 and 3114 to 3117 respectively. Their semantic implications are also highlighted. Consistency and specificity are terms often used in criticizing LCSH. This paper examines the application of these two concepts on the structures believing that a thorough understanding of the syntactic types would help the cataloguer to determine the most appropriate and specific heading to use.

Abstract

PhySH (Physics Subject Headings) was developed by the American Physical Society and first used in 2016 as a faceted hierarchical controlled vocabulary for physics, with some basic terms from related fields. It was developed mainly for the purpose of associating subjects with papers submitted to and published in the Physical Review family of journals. The scheme is organized at the top level with a two-dimensional classification, with one dimension (labeled "disciplines") representing professional divisions within physics, and the other dimension (labeled "facets") providing a conceptual partitioning of terms. PhySH was preceded in use by PACS ("Physics and Astronomy Classification Scheme"), which was in turn preceded by more ad hoc approaches, and this history and related vocabularies or categorizations will also be briefly discussed.

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
