Abstract

Normalization rules are essential for interoperability between bibliographic systems. In the process of working with Name Authority Cooperative Program (NACO) authority files to match records with Functional Requirements for Bibliographic Records (FRBR) and developing the Faceted Application of Subject Terminology (FAST) subject heading schema, the authors found inconsistencies in independently created NACO normalization implementations. Investigating these, the authors found ambiguities in the NACO standard that need resolution, and came to conclusions on how the procedure could be simplified with little impact on matching headings. To encourage others to test their software for compliance with the current rules, the authors have established a Web site that has test files and interactive services showing their current implementation.

Abstract

While many catalogers are using the Web to find the information they need to perform authority work quickly and accurately, the full potential of the Web to assist catalogers in name authority work has yet to be realized. The ever-growing nature of the Web means that available information for creating personal name, corporate name, and other types of headings will increase. In this article, we examine ways in which simple and effective Web searching can save catalogers time and money in the process of authority work. In addition, questions involving evaluating authority information found on the Web are explored.

Abstract

Catalogers have become interdependent in their pursuit to provide bibliographic control and access. This interdependency has brought with it the need for greater agreement in applying common cataloging policies and rules. The expanded application of AACR2 (Anglo-American Cataloguing Rules) is fostering greater uniformity in the provision of bibliographic description and access. The rules have been translated into numerous languages and used in European, Middle Eastern, and Latin American countries. Cataloging committees and individual libraries in Europe and South Africa have expressed strong interest in adopting, adapting, or aligning with AACR2. PCC (Program for Cooperative Cataloguing) is one of the most successful cooperative cataloging efforts and has a considerable international component, which encourages the use of AACR, LCSH (Library of Congress Subject Headings), and MARC. AACR2 is successful on an international level because it is based in internationally developed standards, including ISBDs and the Paris Principles. ISBDs (International Standard Bibliographic Description) and the Functional Requirements for Bibliographic Records are examples of the contributions that IFLA (International Federation of Library Associations and Institutions) has made to the internationalization of cataloging. IFLA sponsored the international conference that resulted in the Paris Principles as well as subsequent projects to craft international policy in relation to uniform headings for persons, corporate bodies, and titles.

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

International efforts to provide authority control include the work of IFLA, the AUTHOR Project funded by the European Commission, and related work conducted under the auspices of the ICA/CDS. IFLA developed the guidelines Form and Structure of Corporate Headings, documented the formulation of names along the lines of national origin in its publication Names of Persons, and published Guidelines for Authority and Reference Entries. Attention has shifted from a single authority record for each entity that would be shared internationally through the exchange of records to linking parallel authority records for the same entity. The access control of the future will account for difference in cataloging rules, transliteration standards, and cultural differences within the same language as well as for the need for different languages and scripts and will enable users to display the script and form of a heading that they expect. Project AUTHOR is a shared set of resource national authority files that used selections from the authority files of France, the United Kingdom, Spain, Portugal, and Belgium. The prototype tested an adaptation of Z39.50 server software for authority records and displays for user interface. An international standard for authority control records has been developed for corporate bodies, persons, and families. Through joint meetings efforts have been synchronized to develop authority control at the international level.

Abstract

The Library of Congress Subject Headings schema (LCSH) is the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST (Faceted Application of Subject Terminology) headings is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains compatibility with LCSH--any valid Library of Congress subject heading can be converted to FAST headings.

Abstract

This paper aims at illustrating the methodology of constructing the Arabic authority headings. Accordingly, the main focus is on the system of linking name headings in Arabic-Roman scripts and subject headings in the three languages Arabic, English and French. The Bibliotheca Alexandrina's biscript / trilingual authority file project »bibalex« can be considered the first step toward establishing cooperative projects with union catalogs and authority files.

Abstract

In 1996, a study was undertaken at the University of Arkansas Libraries to evaluate the practice of front-end authority work for monographs copy cataloging. A sample of 283 name headings originating from Library of Congress, OCLC "Enhance" member, and general member copy was examined, and analysis revealed that 47.3 percent of headings correctly matched authority records already present in the library's local file. Another 41.3 percent exactly matched records in the OCLC authority file. These findings prompted the library to cease checking name headings at the point of cataloging. However, the level of inaccuracies present, combined with the value of authority records for cross-reference and note information, ensured that the Database Maintenance Unit would continue to review local headings reports and perform needed authority work.

Abstract

This paper describes the efforts at the Daniel Cosio Villegas Library of Colegio de Mexico (Mexico) to create a Spanish language authority file on its ALEPH online system. To date, the authorities team, composed of about ten librarians, have created over 10,000 name authorities, and close to 4,000 subject authorities in MARC format, closely following the structure of the Library of Congress Subject Headings (LCSH) records. For the subject authority file, it was decided to establish three levels of description, all of which include the LCSH English term. In order to establish the term in Spanish, seven official sources have been used, with Bilindex (1984) having the highest usage, closely followed by the subject headings list developed by Consejo Superior de Investigaciones Cientificas (CSIC) of Spain. As the first Mexican NACO/SACO participants, librarians at the Colegio de Mexico Library also received training by personnel from the Library of Congress in the creation and validation of subject headings.

Abstract

The implementation of our online integrated catalog ACORN at Vanderbilt University Library has been a complex and time-consuming task. The authority control component represents an important portion of the effort. The authority file consists of approximately one-half million name, subject, series, and uniform title headings, the majority of which were supplied to us by a vendor, Blackwell North America (BNA). Authority work has been integrated into our cataloging routine successfully, new headings are being added to our database daily, and extant headings are being validated online. This paper will cover a description of how Vanderbilt selected the Northwestern Online Total Integrated System (NOTIS); the ongoing editing of the authority file following the BNA processing; the interrelationship of Vanderbilt University Library's three processing units, General Technical Services (GTS), Medical Library, and Law Library apropos of the authority function; and some of the policies and procedures drawn up by the Authority Control Coordinator with the assistance of the other librarians in Monograph and Serial Services.

Abstract

The German subject headings authority file - SWD - provides a terminologically controlled vocabulary, covering all fields of knowledge. The subject headings are determined by the German Rules for the Subject Catalogue. The authority file is produced and updated daily by participating libraries from around Germany, Austria and Switzerland. Over the last twenty years, it grew to an online-accessible database with about 550.000 headings. They are linked to other thesauri, also to French and English equivalents and with notations of the Dewey Decimal Classification. Thus, it allows multilingual access and searching in dispersed, heterogeneously indexed catalogues. The vocabulary is not only used for cataloguing library materials, but also web-resources and objects in archives and museums.

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

Abstract

Explicit authority control of works is essentially non-existent. Our catalogs are built on a principle of controlling headings, and primarily headings for names of authors. Our syndetic structure creates a spider's web of networked relationships among forms of headings, but it ends there, despite the potential richness of depth among bibliographic entities. Effective authority control of works could yield richness in the catalog that would enhance retrieval capabilities. Works are considered to constitute the intellectual content of informative artifacts that may be collected and ordered for retrieval. In a 1992 study the author examined a random sample of works drawn from the catalog of the Georgetown University Library. For each progenitor work, an instantiation network (also referred to as a bibliographic family) was constituted. A detailed analysis of the linkages that would be required for authority control of these networks is reviewed here. A new study is also presented, in which Library of Congress authority records for the works in this sample are sought and analyzed. Results demonstrate a near total lack of control, with only 5.6% of works for which authority records were found. From a sample of 410 works, of which nearly half have instantiation networks, only 23 works could be said to have implicit authority control. However, many instantiation networks are made up of successive derivations that can be implicitly linked through collocation. The difficult work of explicitly linking instantiations comes with title changes, translations, and containing relations. The empirical evidence in the present study suggests that explicit control of expressions will provide the best control over instantiation networks because it is instantiations such as translations, abridgments, and adaptations that require explicit linking.

Abstract

Authority files have played an important role in improving the quality of indexing and subject cataloging. Although authorities can significantly improve search by increasing the number of access points, they are rarely an integral part of the information retrieval process, particularly end-users searches. A retrieval prototype, searchFAST, was developed to test the feasibility of using an authority file as an index to bibliographic records. searchFAST uses FAST (Faceted Application of Subject Terminology) as an index to OCLC's WorldCat.org bibliographic database. The searchFAST methodology complements, rather than replaces, existing WorldCat.org access. The bibliographic file is searched indirectly; first the authority file is searched to identify appropriate subject headings, then the headings are used to retrieve the matching bibliographic records. The prototype demonstrates the effectiveness and practicality of using an authority file as an index. Searching the authority file leverages authority control work by increasing the number of access points while supporting a simple interface designed for end-users.
