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

Today's electronic catalogue makes retrieval of specific records very simple and quick in most (not all) cases, but searches aimed at the reliable retrieval of all material answering a well-defined need (author, work, theme, form, etc.) are still long and tiring, and sometimes impossible, in crowded bibliographic databases. In spite of its great relevance, authority control has been and still is the "poor relative" of cataloguing, the often neglected or overlooked "other half" if we compare it to the creation of bibliographic records. The FRBR study and the new authority control standards (GARR and UNIMARC Authorities) are important steps towards future perspectives. Even today, cataloguing codes do not make clear the difference between the access points for bibliographic records and the relationships (work-to-work, author-to-work, etc.) that are independent from spoecific publications. With the development of richer authority records and relationships, the bibliographic record might be relieved of information related to entities different from publications and of all the functions more suitably worked out upstream or downstream in access systems or by links to the images and/or the texts of the publications themselves. A "light" bibliographic record would no longer be the paramount component of library information systems; it would keep its central role rather as nimble, swift turntable between access and content organization systems and systems for management and display of digital resources themselves.

Abstract

This article describes the project to build the initial International Standard Name Identifier (ISNI) database by deploying the techniques used to develop the Virtual International Authority File (VIAF). It focuses particularly on the work of the OCLC team in transforming the VIAF "resource file" model of matched data into a robust, operational, and authoritative file of uniquely assigned ISNIs as a base for an ongoing ISNI assignment system, and on the quality assurance validation of the database provided by the British Library and the Bibliothèque nationale de France. The need for future interaction between ongoing ISNI assignment and name authority control in libraries is also explored.

This paper looks at approaches to name authority control in repository contexts and describes the work of the Names project, which has been funded to investigate issues surrounding the identification of individuals and institutions within repositories of research outputs in the United Kingdom. The problem of uniquely identifying authors has been with us ever since books have been catalogued. National libraries have been creating name authority files for authors of books for many years, starting with card catalogues and now maintaining electronic files in MARC format. However, authority files for the creators of journal articles do not tend to exist in library systems. The increasing use of subject-based and institutional repositories to hold working papers, reports, research data, and pre-refereed and post-referred versions of articles has led to a corresponding rise in the number of authors identified in such systems. Without having a means of uniquely and unambiguously identifying the creators of materials in repositories, it becomes difficult to be sure whether all the materials related to a particular author will be correctly associated with that individual. Names of authors may be entered in more than one way, or more than one author may have exactly the same name. This article looks at recent attempts to address this problem in the repository environment and goes on to explain the approach that is planned to be taken in the Names project.

Abstract

Some international libraries are still using the Anglo-American Cataloging Rules, 2nd edition revised, for cataloging even though the Library of Congress and other large libraries have retired it in favor of Resource Description and Access. One of these libraries is the National Library of Greece, which consults the Library of Congress database before establishing authorities. There are cultural differences in names and subjects between the Library of Congress and the National Library, but some National Library terms may be more appropriate for users than the Library of Congress-established forms.

Abstract

This article examines the motivations for the collaboration between the British Library and Library of Congress to develop a joint (Anglo-American) authority file. It describes the obstacles that had to be overcome for the British Library to become a Name Authority Cooperative (NACO) "copy holder", or node. It considers the contribution the British Library made to NACO, the benefits it has derived from participation in Program for Cooperative Cataloging (PCC), and concludes by looking ahead to the next 25 years.

Abstract

This article presents a conceptual framework for library name authority control, including methods for disambiguating agents that share the same name and for collocating works of agents who use multiple names. It then discusses the identifier solutions tried or proposed in the library community for name authority control, analyzes the various identity management systems emerging outside of the library community, and envisions future trends in name authority control.

Report of the International Conference on the Principles and Future Development of AACR, 23-25 Oct 1997, Toronto. This conference examined cataloguing principles and rules in light of both description and access within the framework of library catalogues. In particular it focused on bibliographic and authority records and the usability of the library catalogue

Abstract

The teaching of authority control in schools of library and information science has been given little attention until recently. A 2002 article reported that only a little over a third of respondents to a questionnaire believed they had learned about authority control in school. This paper reports a survey of teachers to determine how much authority control is taught in school. Respondents all emphasized the importance of trying to teach authority control to all students of library science and enthusiastically shared their methodologies, while admitting that it is a difficult concept to get across to students. Teachers also face non-understanding from colleagues, lack of course time, and competition from technology courses.

Abstract

Describes the experience of data conversion and migration at the libraries of the Home Office (HO) and the Dept. of the Environment (DoE), UK. Both HO and DoE libraries had changed from Anglo-American code cataloguing to AACR2 cataloguing in the mid-1970s. Both libraries were selective in identifying records for conversion initially to BLAISE-LOCAS. Conversion to integrated library systems from BLAISE-LOCAS MARC tapes produced problems in both libraries with location/holdings fields which were largely resolved at HO, but not resolved at DoE. HO experienced problems converting to a system with fixed field lengths. HO converted subject keywords to form a rudimentary, non-standard thesaurus which required the addition of Broader Term and Narrower Term to meet the challenge of computerized searching. DoE converted a non-thesaurus subject index to an authority file, but continued to maintain the index on a stand-alone DataEase application for use by cataloguers. Neither library converted acquisitions data

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

Since the 1970s the International Federation of Library Associations and Institutions (IFLA) has worked toward establishing an international system of authority control. It concentrated on two main areas: publication of international authority lists, and formulation of international rules for the structure of authority forms. The work of IFLA in these areas is described in this paper.

Abstract

In its role as a national bibliographic agency, the Bibliografia Nazionale Italiana (BNI) has never been in a position to fulfill what should be one of its main functions: authority control. Despite the creation of various committees, studies, and projects, and the close relationship between the BNI and the Servizio Bibliotecario Nazionale (SBN), no plan of action with regard to authority control, whether shared or developed in consultation, has been produced to date. Recently, a significant result was achieved: the specification of the new BNI/UNIMARC database, structured according to authority control principles. And in collaboration with the Region of Tuscany, a project for control of access points destined for the users and librarians of that region is in progress, providing the opportunity to initiate the systematic control of BNI access points. The BNI is now in a position to begin to realize the first objective recommended by the IFLA Working Group on an International Authority System more than twenty years ago: to establish authority headings, including cross-references, for its bibliographic records.

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

Bibliographic data is used to describe resources held in the collections of libraries, archives and museums. That data is mostly available on the Web today and mostly as linked data. Also on the Web are the controlled vocabulary systems of name authority files, like the Virtual International Authority File (VIAF), classification systems, and subject terms. These systems offer their own linked data to potentially help users find the information they want - whether at their local library or anywhere in the world that is willing to make their resources available. We have found it beneficial to merge authority data for names on a global level, as the entities are relatively clear. That is not true for subject concepts and terminology that have categorisation systems developed according to varying principles and schemes and are in multiple languages. Rather than requiring everyone in the world to use the same categorisation/classification system in the same language, we know that the Web offers us the opportunity to add descriptors assigned around the world using multiple systems from multiple perspectives to identify our resources. Those descriptors add value to refine searches, help users worldwide and share globally what each library does locally.

Abstract

Authority control is necessary for meeting the catalog's objectives of enabling users to find the works of an author and to collocate all works of a person or corporate body. This article looks at the current state of authority control as compared to the visions of the 1979 LITA (Library Information and Technology Association) Institutes and the 1984 Authority Control Interest Group. It explores a new view of IFLA's Universal Bibliographic Control (UBC) and a future vision of a virtual international authority file as a building block for the Semantic Web and reinforces the importance of authority control to improve the precision of searches of large databases or the Internet.

Abstract

Discusses the work of the IFLA Working Group of Functional Requirements and Numbering of Authority Records. Describes the activities of the group to build liaison relationships with other sectors of the information community that create and maintain data which is similar to library authority files. Provides a description of the entity-relationship model being developed by the Working Group to extend the FRBR model to cover authority data. (Note: Readers should be aware that the Working Group's entity-relationship model has changed considerably since this paper was written in December 2002.)
