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

Authority control has long been an important part of the cataloging process. However, few studies have been conducted examining how librarians learn about it. Research conducted to date suggests that many librarians learn about authority control on the job rather than in formal classes. To offer an introduction to authority control information for librarians, an annotated bibliography is provided. It includes monographs, articles and papers, electronic discussion groups, Web sites related to professional conferences, additional Web sites related to authority control, and training offered through the Name Authority Cooperative Program and the Subject Authority Cooperative Program. A summary of possible future trends in authority control is also provided.

MARC21 als Austauschformat Die Expertengruppe Datenformate hat in ihrer 5. Sitzung am 22. November 2005 die Frage der Hierarchienabbildung bei der Übernahme von MARC 21 weiter diskutiert und einer Lösung zugeführt. Für einen geringen Prozentsatz der Daten werden trotz Vorarbeiten der Expertengruppe Probleme bei der Überführung von MARC-21-Daten in MAB2-Strukturen gesehen. Es wurde darauf hingewiesen, dass es im Zusammenhang mit dem Umstieg auf MARC 21 ebenso wie bei der kooperativen Katalogisierung notwendig ist, gemeinsame Regeln festzulegen und Absprachen zwischen den Verbünden zu treffen. Eine unterschiedliche Handhabung des Formats sollte sich von vornherein verbieten. Projekt Kooperative Neukatalogisierung Die Projektgruppe hat zweimal getagt, zuletzt am 3. November 2005. Es liegen erste Ergebnisse vor, und spätestens Anfang Januar 2006 soll das Verfahren erprobt werden. Alle Verbünde signalisieren ihr Interesse an dem geplanten Verfahren, da die Eigenkatalogisierungsrate nach wie vor zu hoch ist. Für die Akzeptanz des Dienstes, der auch zum Synchronisieren der vorhandenen Aufnahmen und zum Austausch von Sacherschließungsdaten genutzt werden soll, ist die Aktualität des geplanten Neukatalogisierungspools essentiell. Ein weiteres Ziel ist auch die Optimierung der Arbeitsabläufe zwischen Verbundzentrale und Bibliotheken. Catalogue Enrichment Zur Anreicherung der Katalogdaten gibt es verschiedene Aktivitäten innerhalb der Arbeitsgemeinschaft der Verbundsysteme, die koordiniert werden müssen, damit eine Mehrfachdigitalisierung von Inhaltsverzeichnissen, Abstracts und anderen Objekten vermieden werden kann. Die Arbeitsgemeinschaft der Verbundsysteme beschließt, eine kleine Arbeitsgruppe einzusetzen, die bis spätestens Anfang Februar 2006 einen Vorschlag mit unterschiedlichen Szenarien für unterschiedliche Umgebungen vorlegen soll. Aufgabe der AG Datenanreicherung ist die Konzeption eines schnellen Dienstes für die Digitalisierung von Abstracts und Inhaltsverzeichnissen sofern sie lizenzrechtlich frei verfügbar sind, die allen Verbünden zur Verfügung gestellt werden sollen. Dazu gehören eine Übersicht über die vorhandenen Daten und eine ausgearbeitete Verfahrensvorschrift für das künftige Vorgehen.
Gesamtnachweis aller Bibliotheksbestände in deutschsprachigen Raum Das HBZ hat seinen am 15. November frei geschalteten Dreiländer-Katalog (Deutschland, Österreich, Schweiz) vorgestellt, dessen Ziel der Gesamtnachweis aller Bibliotheksbestände in deutschsprachigen Raum ist. Der Katalog entstand in Kooperation des HBZ mit dem Bibliotheksverbund Bayern (BVB) und dem Österreichischen Bibliothekenverbund (OBV); die Integration weiterer Bibliotheksbestände aus anderen Regionen ist in Arbeit. Realisiert wurde das Projekt mittels der Suchmaschinentechnologie des HBZ, die Antwortzeiten in Bruchteilen von Sekunden, Ranking und Kategorisierung der Treffermengen ermöglicht. Die Mitglieder der Arbeitsgemeinschaft der Verbundsysteme haben beschlossen, sich die für die Literaturversorgung relevanten Verbunddaten (Titeldaten mit Nachweisen) für den Aufbau verbundbezogener, nicht kommerzieller Dienste auf Gegenseitigkeit kostenfrei zur Verfügung zu stellen. Normdateien Online-Schnittstelle Ziel der Online-Kommunikation mit Normdateien ist es, die Arbeit mit den zentralen Normdateien dadurch zu vereinfachen, dass Änderungen an Normdaten in den zentral bei Der Deutschen Bibliothek gehaltenen Dateien mit dem eigenen Client erfolgen können. Ferner sollen alle Änderungen an den Normdateien zeitnah in die Normdaten-Spiegel der Verbundsysteme transportiert werden (Replikation). Das Verfahren soll sich auf alle bei Der Deutschen Bibliothek geführten Normdaten erstrecken. Als standardisiertes Kommunikationsprotokoll soll Z39.50 SR Extended Services Update genutzt werden. Für die Replikation ist OAI vorgesehen, als Austauschformat zunächst MAB2 bzw. MABXML. Die existierenden Implementierungen erfüllen an mehreren wichtigen Stellen nicht die Anforderungen. Eine Konversion in und aus einem neutralen Transportformat, wie für die Online-Kommunikation mit Normdateien benötigt, ist an der gegenwärtigen Pica-Schnittstelle nicht vorgesehen und lässt sich nur realisieren, wenn wesentliche Veränderungen vorgenommen werden. OCLC PICA plant, diese Veränderungen im 1. Quartal 2006 vorzunehmen. Nach der aktuellen Projektplanung soll die Online-Kommunikation zu Beginn des Jahres 2007 starten.
DDC/Melvil-Nutzungs- und Lizenzsituation Die Deutsche Bibliothek hat den Dienst Melvil vorgestellt, der auf der im Rahmen des Projektes DDC Deutsch erstellten deutschen Übersetzung der 22. Ausgabe der DDC basiert, und die Such- und Sprachgewohnheiten deutschsprachiger Benutzerinnen und Benutzer berücksichtigt. Mit Melvil wurde ein Online-Dienst entwickelt, der Bibliotheken und Informationseinrichtungen außer einem an WebDewey orientierten Klassifikationstool MelvilClass auch ein Retrievaltool MelvilSearch für die verbale Suche nach DDC-erschlossenen Dokumenten und das Browsing in der DDC-Hierarchie zur Verfügung stellt. Über die Schnittstelle MelvilSoap können Bibliotheken und Verbundzentralen, die den Dienst Melvil lizenziert haben, auch DDC-Daten zur weiteren Nutzung herunterladen. Gegenwärtig vergibt Die Deutsche Bibliothek Testlizenzen, ab 2006 kann der Dienst nach einem gestaffelten Modell kostenpflichtig genutzt werden Ergebnisse der Adhoc-Arbeitsgruppe ISBD(CR) Der Standardisierungsausschuss hatte in seiner 9. Sitzung am 15. Dezember 2004 die Anpassung der Splitregeln bei fortlaufenden Sammelwerken an die ISBD(CR) mit dem Ziel der Übernahme beschlossen. Im Januar 2005 richtete die Arbeitsstelle für Standardisierung eine Ad-hoc-AG ISBD(CR) ein, in der Vertreter der ZDB, der Expertengruppe Formalerschließung und der AGDBT (Arbeitsgemeinschaft der Datenbankteilnehmer der ZDB) unter der Federführung der Arbeitsstelle für Standardisierung zusammenarbeiteten. Auftragsgemäß konnte dem Standardisierungsausschuss am 2. August 2005 ein entscheidungsreifer Entwurf zur Anwendung der ISBD(CR)-Splitregeln für fortlaufende Sammelwerke vorgelegt werden. Die Unterlage, die dem Standardisierungsausschuss zu seiner 11. Sitzung am 1. Dezember 2005 zugeleitet wurde, wurde den Mitgliedern der Arbeitsgemeinschaft der Verbundsysteme im Vorfeld der Sitzung zur Kenntnis gegeben. Die zeitnahe Anwendung der ISBD(CR)-Splitregeln würde nicht nur in einem kleinen abgeschlossenen Bereich eine Angleichung an internationale Gepflogenheiten bedeuten, sondern sie hätte auch einige positive Auswirkungen auf die von Zeitschriftentiteln abhängigen ergänzenden Dienstleistungen. So würde z.B. die Verlinkung mit SFX-Diensten erheblich erleichtert."

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

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

«Current proposals for the future of the Web describe the use of ontologies for making the Web more intelligent for machine and automatic processing. The Virtual International Authority File (VIAF) could be one of the basic building blocks to a »semantic web« when combined with other controlled vocabularies and authority files from such sources as abstracting and indexing services, archives, museums, publishers, etc. Libraries now have an opportunity to make a great contribution to this future and should help make this vision a reality.« This article gives a status report on the VIAF, a cooperative project of the Library of Congress, the Bibliotheque nationale de France, OCLC and the German National Library.

Abstract

Forty years ago the ICCP in Paris laid the foundations of international co-operation in descriptive cataloging without explicitly speaking of authority control. Some of the factors in the evolution of authority control are the development of catalogs (from card catalog to local automation, to today's OPAC on the Web) and services provided by libraries (from individual service to local users to system networks, to the World Wide Web), as well as international agreements on cataloging (from Paris Principles to the UBC programme, to the report on Mandatory data elements for internationally shared resource authority records). This evolution progressed from the principle of uniform heading to the definition of authority entries and records, and from the responsibility of national bibliographic agencies for the form of the names of their own authors to be shared internationally to the concept of authorized equivalent heading. Some issues of the present state are the persisting differences among national rules and the aim of respecting both local culture and language and international readability.

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

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

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

This article presents an overview of the LEAF project (Linking and Exploring Authority Files)1, which has set out to provide a framework for international, collaborative work in the sector of authority data with respect to authority control. Elaborating the virtues of authority control in today's Web environment is an almost futile exercise, since so much has been said and written about it in the last few years.2 The World Wide Web is generally understood to be poorly structured-both with regard to content and to locating required information. Highly structured databases might be viewed as small islands of precision within this chaotic environment. Though the Web in general or any particular structured database would greatly benefit from increased authority control, it should be noted that our following considerations only refer to authority control with regard to databases of "memory institutions" (i.e., libraries, archives, and museums). Moreover, when talking about authority records, we exclusively refer to personal name authority records that describe a specific person. Although different types of authority records could indeed be used in similar ways to the ones presented in this article, discussing those different types is outside the scope of both the LEAF project and this article. Personal name authority records-as are all other "authorities"-are maintained as separate records and linked to various kinds of descriptive records. Name authority records are usually either kept in independent databases or in separate tables in the database containing the descriptive records. This practice points at a crucial benefit: by linking any number of descriptive records to an authorized name record, the records related to this entity are collocated in the database. Variant forms of the authorized name are referenced in the authority records and thus ensure the consistency of the database while enabling search and retrieval operations that produce accurate results. On one hand, authority control may be viewed as a positive prerequisite of a consistent catalogue; on the other, the creation of new authority records is a very time consuming and expensive undertaking. As a consequence, various models of providing access to existing authority records have emerged: the Library of Congress and the French National Library (Bibliothèque nationale de France), for example, make their authority records available to all via a web-based search service.3 In Germany, the Personal Name Authority File (PND, Personennamendatei4) maintained by the German National Library (Die Deutsche Bibliothek, Frankfurt/Main) offers a different approach to shared access: within a closed network, participating institutions have online access to their pooled data. The number of recent projects and initiatives that have addressed the issue of authority control in one way or another is considerable.5 Two important current initiatives should be mentioned here: The Name Authority Cooperative (NACO) and Virtual International Authority File (VIAF).

Abstract

Work on a prototype of the new Soggettario (the main Italian subject heading list) has begun in October 2004 at the Central National Library of Florence (BNCF). BNCF is involving in the renewal of the most used subject indexing tool of Italian libraries. The project had already produced a Feasibility Study, representing a reference for the works which have started recently. An Italian abstract of the Feasibility Study, and more documentation, can be found in the BCNF website at the Web address <http://www bncf.firenze.sbn.it/progetti/>. Together with the project team and the BNCF staff, some young external consultants are working, who are focusing on the terminological component of the system, namely the prototype of the Thesaurus. At the same time, documents are produced which define procedures, establish criteria, and give guidelines. The list of items by which the prototype started consists of: - the terms included in the updates provided by the Italian National Bibliography (BNI) during the period 1986-1998 (already published in the form of lists); - the items introduced from 1999 to 2005 - other items introduced in the past years but never recorded; - some terms from the Soggettario (1956) or from BNI updates (1956-19S5), being especially outdated and needing revision. In building the semantic networks and the hierarchies, and in making the terminological control, of course, more terms have to be included, which come from the Soggettario, the BNI and other authoritative sources both catalographic (various indexing tools) and lexicographic (general and special directories). DDC numbers are also related to the terms in the Thesaurus. The prototype, to be completed in April 2006, will include a sample of terms for each disciplinary area. About 5000 terms will have a complete structure, but 6000 more will be included in the Thesaurus in order to fill the semantic networks, and marked with a different working status. For the prototype the AgroVoc software is used, which has been provided by FAO and adapted by the BNCF computing staff in order to match the specific requirements of the project. Thanks to the potential of this software, we intend to test in future on the multilingual side of terminology. Such work is likely to begin by testing links to the corresponding forms used by the Library of Congress. We are currently beginning to focus on this, and we wish that external parties be involved which are concerned with multilingual terminology in more or less specialistic contexts. We will follow the road of conventions with Italian universities, which could cooperate to this development through their students and graded students. We are also looking at the developments in the work of the British BSI working group on standards for thesauri convened by Stella Dextre Clarke.
