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

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

Die Deutsche Bibliothek, the Library of Congress, and OCLC Online Computer Library Center are jointly developing a virtual international authority file (VIAF) for personal names which links authority records from the world's national bibliographic agencies and will be made freely available on the Web. The goals of the project are to prove the viability of automatically linking authority records from different national authority files and to demonstrate its benefits. The authority and bibliographic files from the Library of Congress and Die Deutsche Bibliothek were used to create the initial VIAF which contains over six million names with over a half million links. A key aspect of the project was the development of automated name matching algorithms which use information from both authority records and the corresponding bibliographic records. The practicality of algorithmically linking the personal names between national authority files was demonstrated; seventy percent of the authority records for personal names common to both files were automatically linked with an error rate of less than one percent. The long-term goal of the VIAF project is to combine the authoritative names from many national libraries and other significant sources into a shared global authority service.

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.
