Abstract

In this paper I describe a conceptual design of a bibliographic retrieval system that enables more thourough control of bibliographic entities. A bibliographic entity has 2 components: the intellectual work and the physical item. Users searching bibliographic retrieval systems generally do not search for a specific item, but are willing to retrieve one of several alternative manifestations of a work. However, contemporary bibliographic retrieval systems are based solely on the descriptions of items. Works are described only implcitly by collocating descriptions of items. This method has resulted in a tool that does not include important descriptive attributes of the work, e.g. information regarding its history, its genre, or its bibliographic relationships. A bibliographic relationship is an association between 2 bibliographic entities. A system evaluation methodology wasused to create a conceptual schema for a bibliographic retrieval system. The model is based upon an analysis of data elements in the USMARC Formats for Bibliographic Data. The conceptual schema describes a database comprising 2 separate files of bibliographic descriptions, one of works and the other of items. Each file consists of individual descriptive surrogates of their respective entities. the specific data content of each file is defined by a data dictionary. Data elements used in the description of bibliographic works reflect the nature of works as intellectual and linguistic objects. The descriptive elements of bibliographic items describe the physical properties of bibliographic entities. Bibliographic relationships constitute the logical strucutre of the database

Abstract

Discusses the issues involved in the development of data formats for computerized information retrieval systems. Integrated databases capable of holding both bibliographic and factual information, in a single database structure, are more convenient for searching and retrieval by end users. Several bibliographic formats have been developed and are used for these bibliographic control puposes. Reviews features of 6 major bibliographic formats: USMARC, UKMARC, UNIMARC, CCF, MIBIS and ABNCD are reviewed. Only 2 formats: CCF and ABNCD are capable of holding both bibliographic and factual information and supporting the design of integrated databases. The comparison suggests that, while CCF makes more detailed provision for bibliographic information, ABNCD makes better provision for factual information such as profiles of institutions, information systems, projects and human experts

Abstract

Paper presented at a symposium on 'Implementing the Art and Architecture Thesaurus (AAT): Controlled Vocabulary in the Extended MARC format', held at the 1989 Annual Conference of the Art Libraries Society of North America. Describes how changes are effected in MARC and the role of the various groups in the library community that are involved in the implementing these changes. Discusses the expansion of the formats to accomodate cataloguing and retrieval for visual materials. Expanded capabilities for coding visual materials offer greater opportunity for user access.

Abstract

Surveys how the USMARC integrated bibliographic format (UBIF) could be mapped onto an hypermedia document USMARC format (HDUF) to meet the requirements of a hypermedia document control/retrieval/delivery (HDRD) system for the Internet. Explores the characteristics of such a system using an example of the WWW's directory and searching engine Yahoo!. Discusses additional standard specifications for the UBIF's structure, content designation, and data content to map this format into the HDUF that can serve as a proxy for the Net HDRD system

Abstract

This article explores recent discussions about appropriate mark-up conventions for library information intended for use on the World Wide Web. In particular, the question of whether the MARC 21 format will continue to be useful and whether the time is right for a full-fledged conversion effort to XML is explored. The author concludes that the MARC format will be relevant well into the future, and its use will not hamper access to bibliographic information via the web. Early XML exploratory efforts carried out at the Stanford University's Lane Medical Library are reported on. Although these efforts are a promising start, much more consultation and investigation is needed to arrive at broadly acceptable standards for XML library information encoding and retrieval.

Abstract

Currently, few resources exist to guide libraries in the cataloguing of community information using the new USMARC Format for Cammunity Information (1993). In developing a community information database, Queens Borough Public Library, New York City, formulated their own cataloguing procedures for applying AACR2, LoC File Interpretations, and USMARC Format for Community Information to community information. Their practices include entering corporate names directly whenever possible and assigning LC subject headings for classes of persons and topics, adding neighbourhood level geographic subdivisions. The guidelines were specially designed to aid non cataloguers in cataloguing community information and have enabled library to maintain consistency in handling corporate names and in assigning subject headings, while creating database that is highly accessible to library staff and users

Abstract

Contribution to an issue devoted to serials and reference services. Familiarity with the basic elements of the MARC format and their effect on the display and retrieval of bibliographic data is an essential element of public service in those libraries with MARC-based on-line catalogues. Describes the components of a MARC record. To successfully retrieve the information sought from an on-line catalogue, the catalogue user must know whether it is in an indexed field and, if so, must be familiar with the search strategies required by the system.

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

This paper brings light to the existing practice of cataloging in the college libraries of Assam in terms of utilizing the MARC 21 standard and its structure, i.e., the tags, subfield codes, and indicators. Catalog records from six college libraries are collected and a survey is conducted to understand the local users' information requirements for the catalog. Places, where libraries have scope to improve and which divisions of tags could be more helpful for them in information retrieval, are identified and suggested. This study fulfilled the need for local-level assessment of the catalogs.

Abstract

Catalogues have evolved from lists of physical items present in particular libraries into computerized access and retrieval tools for works dispersed across local and national boundaries. Works themselves are no longer constrained by physical form yet cataloguing rules have not evolved in parallel with these developments. Reanalyzes the nature of works and their publication in an approach based on object oriented modelling and demonstrates the advantages to be gained thereby. Suggests a strategic plan to enable an organic transformation to be made from current MARC based cataloguing to object oriented cataloguing. Proposes major revisions of MARC in order to allow records to maximize the benefits of both computerized databases and high speed data networks. This will involve a fundamental shift away from the AACR philosophy of description of, plus access to, physical items

Abstract

Computers play an important role in the development of bibliographic databases. Exchange formats are needed for the generation and exchange of bibliographic data at different levels: international, national, regional and local. Discusses the formats available at national and international level such as the International Standard Exchange Format (ISO 2709); the various MARC formats and the Common Communication Format (CCF). Work on Indian standards involving the Bureau of Indian Standards, the National Information System for Science and Technology (NISSAT) and other institutions proceeds only slowly

Abstract

T.1: Today's thesauri are mostly electronic tools, having moved on from the paper-based era when thesaurus standards were first developed. They are built and maintained with the support of software and need to integrate with other software, such as search engines and content management systems. Whereas in the past thesauri were designed for information professionals trained in indexing and searching, today there is a demand for vocabularies that untrained users will find to be intuitive. ISO 25964 makes the transition needed for the world of electronic information management. However, part 1 retains the assumption that human intellect is usually involved in the selection of indexing terms and in the selection of search terms. If both the indexer and the searcher are guided to choose the same term for the same concept, then relevant documents will be retrieved. This is the main principle underlying thesaurus design, even though a thesaurus built for human users may also be applied in situations where computers make the choices. Efficient exchange of data is a vital component of thesaurus management and exploitation. Hence the inclusion in this standard of recommendations for exchange formats and protocols. Adoption of these will facilitate interoperability between thesaurus management systems and the other computer applications, such as indexing and retrieval systems, that will utilize the data. Thesauri are typically used in post-coordinate retrieval systems, but may also be applied to hierarchical directories, pre-coordinate indexes and classification systems. Increasingly, thesaurus applications need to mesh with others, such as automatic categorization schemes, free-text search systems, etc. Part 2 of ISO 25964 describes additional types of structured vocabulary and gives recommendations to enable interoperation of the vocabularies at all stages of the information storage and retrieval process.
T.2: The ability to identify and locate relevant information among vast collections and other resources is a major and pressing challenge today. Several different types of vocabulary are in use for this purpose. Some of the most widely used vocabularies were designed a hundred years ago and have been evolving steadily. A different generation of vocabularies is now emerging, designed to exploit the electronic media more effectively. A good understanding of the previous generation is still essential for effective access to collections indexed with them. An important object of ISO 25964 as a whole is to support data exchange and other forms of interoperability in circumstances in which more than one structured vocabulary is applied within one retrieval system or network. Sometimes one vocabulary has to be mapped to another, and it is important to understand both the potential and the limitations of such mappings. In other systems, a thesaurus is mapped to a classification scheme, or an ontology to a thesaurus. Comprehensive interoperability needs to cover the whole range of vocabulary types, whether young or old. Concepts in different vocabularies are related only in that they have the same or similar meaning. However, the meaning can be found in a number of different aspects within each particular type of structured vocabulary: - within terms or captions selected in different languages; - in the notation assigned indicating a place within a larger hierarchy; - in the definition, scope notes, history notes and other notes that explain the significance of that concept; and - in explicit relationships to other concepts or entities within the same vocabulary. In order to create mappings from one structured vocabulary to another it is first necessary to understand, within the context of each different type of structured vocabulary, the significance and relative importance of each of the different elements in defining the meaning of that particular concept. ISO 25964-1 describes the key characteristics of thesauri along with additional advice on best practice. ISO 25964-2 focuses on other types of vocabulary and does not attempt to cover all aspects of good practice. It concentrates on those aspects which need to be understood if one of the vocabularies is to work effectively alongside one or more of the others. Recognizing that a new standard cannot be applied to some existing vocabularies, this part of ISO 25964 provides informative description alongside the recommendations, the aim of which is to enable users and system developers to interpret and implement the existing vocabularies effectively. The remainder of ISO 25964-2 deals with the principles and practicalities of establishing mappings between vocabularies.

Abstract

The MARC standard for representing catalogue records and the Z39.50 standard for locating and retrieving them have facilitated interoperability in the library domain for more than a decade. With the increasing ubiquity of XML, these standards are being superseded by MARCXML and MarcXchange for record representation and SRW/U for searching and retrieval. Service providers moving from the older standards to the newer generally need to support both old and new forms during the transition period. YAZ Proxy uses a novel approach to provide SRW/MARCXML access to the Library of Congress catalogue, by translating requests into Z39.50 and querying the older system directly. As a fringe benefit, it also greatly accelerates Z39.50 access.

Abstract

The chief of cataloguing policy and support office at the LoC presents her views on the usefulness of conceptual modelling in determining future directions for cataloguing and the MARC format. After describing the evolution of bibliographic processes, suggests usign the entity-relationship conceptual model to step back from how we record information today and start thinking about what information really means and why we provide it. Argues that now is the time to reexamine the basic principles which underpin Anglo-American cataloguing codes and that MARC formats should be looked at to see how they can evolve towards a future, improved structure for communicating bibliographic and authority information
