Abstract

The system is available both in print and online versions. Names a few new subject headings in areas like science, technology, engineering and medicine (STEM). In this edition, there are a total of 1,600 new headings making it a total of 12,000+ preferred headings meant for subject access in small and medium sized libraries. This unprecedented increase of about 1,600 headings is mostly due the complete incorporation of the Canadian Sears last published independently in 2006. Also critically examines inconsistencies in a few headings. Concludes to say the new edition in resplendent, hard binding maintains its stellar reputation of a handy list of general subject headings both for applications and a teaching resource.

Abstract

Evaluative and comparative studies of catalog data have tended to focus on methods that are labor intensive, demand expertise, and can examine only a limited number of records. This study explores an alternative approach to gathering and analyzing catalog data, focusing on the currency and consistency of controlled headings. The resulting data provide insight into libraries' use of changed headings and their success in maintaining currency and consistency, and the systems needed to support the current pace of heading changes.

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

Although the rules for descriptive cataloging have been recodified twice in the past twenty years, there never has been any kind of comprehensive theoretical code for subject headings, despite some suggestions for a code over the years. This essay explains the need for a code, provides historical background, and presents some broad proposals as to the philosophy, structure, and form of the code and what the code should cover. Included is the relation between the proposed code and the Library of Congress' 1984 Subject Cataloging Manual.

Abstract

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

Library of Congress Subject Headings (LCSH), a system originally designed as a tool for subject access to the Library's own collection in the late nineteenth century, has become, in the course of the last century, the main subject retrieval tool in library catalogs throughout the United States and in many other countries. It is one of the largest non-specialized controlled vocabularies in the world. As LCSH enters a new century, it faces an information environment that has undergone vast changes from what had prevailed when LCSH began, or, indeed, from its state in the early days of the online age. In order to continue its mission and to be useful in spheres outside library catalogs as well, LCSH must adapt to the multifarious environment. One possible approach is to adopt a series of scalable and flexible syntax and application rules to meet the needs of different user communities

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

Many kinds of structure can be discerned in the headings and rules governing the Library of Congress Subject Headings. By addressing these structures at different levels, librarians can develop different approaches to the machine-assisted validation of subject headings, from the checking of individual words to the validation of complex forms of heading/subdivision compatibility. Using computer programs to assist with maintenance of subject headings is becoming increasingly necessary as technical services librarians strive to create consistent and useful patterns of subject collocation in library catalogs

Abstract

This paper presents a study that assessed the feasibility of applying the approach of the Faceted Application of Subject Terminology (FAST), an initiative of the Online Computer Library Center (OCLC), to records in the Ulrich's Periodicals Directory.? The goal is to determine whether a simplified application of Library of Congress Subject Headings (LCSH), as illustrated by FAST, would benefit the Ulrich's system. This feasibility study found that although a few problems were encountered in the process, overall the FAST database was useful for converting Ulrich's subject headings into FAST headings.

Abstract

Library of Congress Subjecl Headings retrieved as the results of a search in an online catalog are likely to be filed in straight alphabetical, word-by-word order, ignoring the semantic structures of these headings and scattering headings of a similar type. This practice makes LC headings unnecessarily difficult to use and negates much of their indexing power. Enthusiasm for filing simplicity and postcoordinate indexing are likely contributing factors to this phenomenon. Since the report Headings for Tomorrow (1992) first raised this issue, filing practices favoring postcoordination over precoordination appear to have become more widespread and more entrenched

Rez. in: KO 35(2008) no.1, S.55-58 (M.P. Satija): "The Sears List, first published in 1923, has survived times of destabilizing changes while keeping reasonable continuity with the past. Dr. Joseph Miller, at the helm since 1992 and the longest-serving editor in the eighty-four years of the List's existence, first edited the 15th edition of the Sears (1994). Over the years, the Sears has achieved more than it had hoped for: ever-increasing use the world over. In fact, the turbulent progress of media and information theories has forced the Sears to keep up with the changing times. Knowledge organization is a shifting sand in the electronic era. Vast and varied changes generate not only new information, but also new terms and phrases. It is trite to say that the electronic media have transformed the way in which we access information and knowledge. The new edition of the Sears has absorbed these changes to reflect the times. The 19th edition, released in May 2007, has about 440 new headings, to bring the new total to over 8000 headings, which keeps the growth rate at five percent. Newly-added headings generally fall into one of two categories: a) headings for the new and current subjects and b) headings previously missed. A few more have been modified. New editions are produced regularly to: - incorporate terms for new subjects, - restructure the form of old headings to suit the changing information needs and informationseeking behaviour of the users, - add new terms to old subject headings to reflect current usage, - delete the obsolete subjects, - forge new relations between subjects and their terms. Two major areas of new additions are in the fields of Islam, as might be expected, and the graphic novel- the latter has thirty headings perhaps drawn from the WilsonWeb Database on Graphic Novels Core Collection. ... The lapses are minor and could be forgiven; they in no way detract from this continuously-expanding and well-established tool for subject-cataloguing in small and medium libraries. The handy List and its lucid introduction make Sears an excellent and convenient tool for teaching subject headings' use and principles, as well as methods of vocabulary control. With its glossy and flowery cover, clear typeface and high production standards, the new edition is particularly welcome."
