Abstract

This paper traces the efforts made by IFLA (the International Federation of Library Associations and Institutions over the past three decades to promote the concept of Universal bibliographic Control in relation to authorities and authority control. It covers the work done by various groups within IFLA to develop standards for personal and corporate name headings, for authority and reference entries, and for UNIMARC/Authorities. The paper concludes with a summary of possible models for the future development of a systems infrastructure for international authority control.

"Subject headings Many Italian libraries create subject headings for their catalogues, using as a reference guide the "Soggettario per i catalogui delle biblioteche italiane." This is basically a list of subject terms created by the Biblioteca nazionale centrale di Firenze (BNCF), first published in 1956 and later updated with various lists of new subject headings. Though the Soggettario is still the main available reference, librarians are generally aware that it is outdated in both vocabulary and structure, especially as it does not provide explicit principles and rules to create and combine subject headings. A research group, called the Gruppo di ricerca sull'indicizzazione per soggetto (GRIS), was founded in 1990. It was devoted to improving the principles and consistency of subject indexing. Its members have performed in depth investigations of the structure of subject headings, starting with the principles of facet analysis used in PRECIS and including original developments. Results of their work are coded into the Guida all'indicizzazione per soggetto, published in 1996 and available also online <http:// wwwaib.it/aib/commiss/gris/gulda.htm>. The GRIS guide does not concern vocabulary, but morphological and syntactical rules for choosing and combining terms according to a sound citation order, based an a "role scheme." Unfortunately, GRIS principles have been applied only in a small number of libraries, mainly in Tuscany, rohere most GRIS members are located. A new project is now attempting to blend the traditional authority of the Soggettario with the more advanced principles of GRIS. A working group has been formed with people from BNCF, GRIS, and others, to study the feasibility of a renewal of the Soggettario. The group produced a report book in 2002, specifying the desirable features of the new system, and is at present searching for grants to implement it.

Abstract

Authority files have played an important role in improving the quality of indexing and subject cataloging. Although authorities can significantly improve searching 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 Faceted Application of Subject Terminology (FAST) as an index to OCLC's WorldCat.org bibliographic database. The searchFAST prototype 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.

Abstract

This paper compares one hundred corporate names listed in the National Authority File (LC NAF) on OCLC with the corporate names listed on official corporate web pages collected between October 1st and November 30th, 2001 in order to understand and evaluate their differences. Twenty five percent of corporate names found in the National Authority File are different from the form of corporate names found on official corporate web pages in this study. This creates a concern that users may not be finding everything issued by corporate bodies in library catalogs. Which form of corporate names should catalogers use as the authorized headings?

Abstract

Discusses the function of MARC field 670 in providing AACR authority control in OPACs through the AAAF: where field 670 is used to justify the form of content of established headings and their cross references. Reports results of a study of field 670 entries from national name authority records pertaining to the subject area of the Catholic Church in terms of: the number of field 670 entries per record; types of work cited; and information on the work themselves. Results indicate that considerable differences exist among the categories of authority records, with some (modern personal names and uniform titles) being more amenable to computerized generation. It was found possible to identify tentatively a core reference for authority work in a subject area

Abstract

This presentation attempts to fit the subject contribution mechanism used in the Program for Cooperative Cataloging's SACO Program into the context of subject gateways. The discussion points to several subject gateways and concludes that there is no similarity between the two. Subject gateways are a mechanism for facilitating searching, while the SACO Program is a cooperative venture that provides a "gateway" for the development of LCSH (Library of Congress Subject Heading list) into an international authority file for subject headings.

Abstract

Shared authority files and cooperation in the development of national lists, both author and subject, have enabled libraries to share resources and improve access to their collections. As we move from national resource sharing to a more international approach, we face problems accessing catalogues in other languages. By creating links between existing subject heading languages (initially in French, German, and English), MACS (Multilingual Access to Subjects) allows users to carry out searches in major national library collections in Europe using subject headings in their own languages. An operational service will be available in 2004.

Abstract

Controlled vocabularies are a foundational concept in library science and provide a framework for consistency in cataloging practices. Subject headings provide valuable access points to library resources during search and discovery for patrons. Many librarians will be familiar with the more widely used controlled vocabularies, like those maintained by national libraries or major professional organizations. More recently, there has been an increasing shift toward specialized vocabularies maintained by independent entities intended for much narrower use. While there is valid criticism of the nature or content of controlled vocabularies, they will likely continue to be an important feature in information organization.

Abstract

Bibliographic records can include information from controlled vocabularies to capture identities about individuals, especially about authors or intended audiences; personal name authority records can also contain information about identity. Employing a systematic analysis of the overlap of the Homosaurus, Library of Congress Subject Headings (LCSH), and Library of Congress Demographic Group Terms (LCDGT), this article explores the extent to which LGBTQ+ identities are represented in the three vocabularies. Despite LCSH's long, iterative history of development and the faceted, post-coordinate nature of LCDGT, neither vocabulary was found to be adequate in covering the complex, LGBTQ+ identities represented in the Homosaurus.

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

The project of the renewal of the Subject Headings for Italian Library Catalogues (Soggettario), financed by the National Central Library in Florence, proposes a pre-coordinated language, both analytic and synthetic, complying with international rules on vocabulary control and structure, based on category analysis of semantic relationships. It envisages a strict distinction between semantic relationships and syntactic ones, and bases its citation order of subject strings on the analysis model for logical relationships. Thanks to its features, the new Soggettario agrees both with the logic of Guidelines for Subject Authority and Reference Entries and of UNIMARC. Authorities, and with FRBR (Functional Requirements for Bibliographic Records). The rigorous structure of the thesaurus will facilitate the transfer of controlled terminology to lists or authority files and archives. The Italian National Bibliography (BNI) will have to play a leading role on the control of coherence of semantic access points. It will validate the strings created by other libraries and control their coherence according to the syntax rules envisaged in the new method.

Abstract

The paper presents experiences and challenges encountered during the planning and creation of the Universal Decimal Classification (UDC) authority database in the National and University Library in Zagreb, Croatia. The project started in 2014 with the objective of facilitating classification data management, improving the indexing consistency at the institutional level and the machine readability of data for eventual sharing and re-use in the Web environment. The paper discusses the advantages and disadvantages of UDC, which is an analytico-synthetic classification scheme tending towards a more faceted structure, in regard to various aspects of authority control. This discussion represents the referential framework for the project. It determines the choice of elements to be included in the authority file, e.g. distinguishing between syntagmatic and paradigmatic combinations of subjects. It also determines the future lines of development, e.g. interlinking with the subject headings authority file in order to provide searching by verbal expressions.

Abstract

During the retrospective conversion of its printed and card catalogues, the Bibliothèque nationale de France was confronted with the existence of old bibliographic records without corporate body headings, because this concept was unknown when the books were catalogued. The Library launched two programs aimed at creating authority records for specific fields important for the access to the national bibliographic heritage, respectively named COFAR -- for the official corporate bodies, mainly national and preceding the French Revolution - and CORELI - for the religious corporate bodies (parishes, dioceses, confraternities, orders and congregations, etc.). The 2550 records created by the COFAR and CORELI programs have been included in the authority file of BNOPALE PLUS; so they are visible either via the online catalogue or separately with other authority records. They give librarians an extra tool for identifying entities. They represent also a valuable source of information accessible to anyone who takes an interest in the history of French government institutions or religious entities.

Abstract

From the very beginnings of library automation, subject authority control has been considered an important bibliographic tool in the Czech National Library (CNL). Effective subject access cannot exist without standardised access points. Subject authorities are considered an indispensable reference tool in supporting the selection of subject access points and normalizing content indexing. Most importantly, they are heavily relied upon when it comes to customisation of links between bibliographic records and subject access points in order to create a user-friendly subject browsing and searching environment. Because of the fact that the Universal Decimal Classification (UDC) is widely used in Czech Libraries it has become a readily available language independent subject framework which can be complemented by a more user-friendly subject heading system. In this context, the subject authority control offers a means of enhancing subject headings' access points with terminology and the semantic links available in UDC. Furthermore classification is used to enrich relationships between authority records themselves. The author will discuss in more detail the different aspects and advantages of subject authorities in which a classification and a subject heading system complement one another and the way this is implemented in the CNL.
