    Abstract
    The current library bibliographic infrastructure was constructed in the early days of computers - before the Web, XML, and a variety of other technological advances that now offer new opportunities. General requirements of a modern metadata infrastructure for libraries are identified, including such qualities as versatility, extensibility, granularity, and openness. A new kind of metadata infrastructure is then proposed that exhibits at least some of those qualities. Some key challenges that must be overcome to implement a change of this magnitude are identified.

    Abstract
    One of the big challenges facing academic libraries today is to increase the relevance of the libraries to their user communities. If the libraries can increase the visibility of their resources on the open web, it will increase the chances of the libraries to reach to their user communities via the user's first search experience. BIBFRAME and library Linked Data will enable libraries to publish their resources in a way that the Web understands, consume Linked Data to enrich their resources relevant to the libraries' user communities, and visualize networks across collections. However, one of the important steps for transitioning to BIBFRAME and library Linked Data involves crosswalks, mapping MARC fields and subfields across data models and performing necessary data reformatting to be in compliance with the specifications of the new model, which is currently BIBFRAME 2.0. This article looks into how the Library of Congress has mapped library bibliographic data from the MARC format to the BIBFRAME 2.0 model and vocabulary published and updated since April 2016, available from http://www.loc.gov/bibframe/docs/index.html based on the recently released conversion specifications and converter, developed by the Library of Congress with input from many community members. The BIBFRAME 2.0 standard and conversion tools will enable libraries to transform bibliographic data from MARC into BIBFRAME 2.0, which introduces a Linked Data model as the improved method of bibliographic control for the future, and make bibliographic information more useful within and beyond library communities.

    Abstract
    Catalogs have for centuries been the main tool that enabled users to search for items in a library by author, title, or subject. A catalog can be interpreted as a set of bibliographic records, where each record acts as a surrogate for a publication. Every record describes a specific publication and contains the data that is used to create the indexes of search systems and the information that is presented to the user. Bibliographic records are often captured and exchanged by the use of the MARC format. Although there are numerous rdquodialectsrdquo of the MARC format in use, they are usually crafted on the same basis and are interoperable with each other -to a certain extent. The data model of a MARC-based catalog, however, is rdquo[...] extremely non-normalized with excessive replication of datardquo [1]. For instance, a literary work that exists in numerous editions and translations is likely to yield a large result set because each edition or translation is represented by an individual record, that is unrelated to other records that describe the same work.

    Abstract
    Electronic documents are creating new services and generating new demands, with consequent impacts on the means of transmitting knowledge, international standards and democratisation of access. Universal bibliographic control depends on common rules for bibliographic description and format to ensure compatibility and exchange. In addition to ISBN and UNIMARC for cataloguing, Z39.50 allows searching of heterogeneous databases and SGML makes cataloguing in publication a reality. Such developments must be based on knowledge of what users want and their real search and consultation practices, not what the system devisers have the technology to create

    Abstract
    In response to libraries' frustration over their rich resources being invisible on the web, Zepheira, at the request of the Library of Congress, created BIBFRAME, a bibliographic metadata framework for cataloging. The model replaces MARC records with linked data, promoting resource visibility through a rich network of links. In place of formal taxonomies, a small but extensible vocabulary streamlines metadata efforts. Rather than using a unique bibliographic record to describe one item, BIBFRAME draws on the Dublin Core and the Functional Requirements for Bibliographic Records (FRBR) to generate formalized descriptions of Work, Instance, Authority and Annotation as well as associations between items. Zepheira trains librarians to transform MARC records to BIBFRAME resources and adapt the vocabulary for specialized needs, while subject matter experts and technical experts manage content, site design and usability. With a different approach toward data modeling and metadata, previously invisible resources gain visibility through linking.

    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

    Hessisches BibliotheksinformationsSystem (HEBIS) Personennamendatei (PND) Vor dem Hintergrund der Harmonisierungsbestrebungen bei den Normdateien hat der HeBIS-Verbundrat nach erneuter Diskussion mehrheitlich entschieden, künftig neben SWD und GKD auch die PND als in HeBIS integrierte Normdatei obligatorisch zu nutzen. Im Zuge der wachsenden Vernetzung der regionalen Verbundsysteme kommt der Homogenität der Datensätze eine zunehmend wichtigere Bedeutung zu. Konkret wird dies speziell für HeBIS mit dem Produktionsbeginn des HeBIS-Portals und der integrierten verbundübergreifenden Fernleihe. Nur wenn die Verfasserrecherche in den einzelnen Verbunddatenbanken auf weitgehend einheitliche Datensätze einschließlich Verweisungsformen trifft, kann der Benutzer gute Trefferergebnisse erwarten und damit seine Chancen erhöhen, die gewünschte Literatur über Fernleihe bestellen zu können. Das Gesamtkonzept ist ausgelegt auf eine pragmatische und aufwandsreduzierte Vorgehensweise. Mit der Umsetzung wurde begonnen. Hochschulbibliothekszentrum des Landes Nordrhein-Westfalen (HBZ) FAST-Suchmaschine Das HBZ hat die Suchmaschinentechnologie des norwegischen Herstellers FAST lizenziert. Ziel ist es, die Produkte des HBZ mit Hilfe innovativer Suchmaschinentechnologien in einer neuen Ausrichtung zu präsentieren. Die Präsentation soll einen schnellen Recherche-Zugang zu den NRWVerbunddaten mittels FAST-Suchmaschinentechnologie mit folgenden Eigenschaften beinhalten: - Eine Web-Oberfläche, um für Laien eine schnelle Literatursuche anbieten zu können. - Eine Web-Oberfläche, um für Expertinnen und Experten eine schnelle Literatur-Suche anbieten zu können. - Präsentation von Zusatzfunktionen, die in gängigen Bibliothekskatalogen so nicht vorhanden sind. - Schaffung einer Zugriffsmöglichkeit für den KVK auf die Verbunddaten mit sehr kurzen Antwortzeiten Digitale Bibliothek Die Mehrzahl der Bibliotheken ist inzwischen auf Release 5 umgezogen. Einige befinden sich noch im Bearbeitungsstatus. Von den letzten drei Bibliotheken liegen inzwischen die Umzugsanträge vor. Durch die Umstrukturierung der RLB Koblenz zum LBZ Rheinland-Pfalz werden die Einzelsichten der RLB Koblenz, PLB Speyer und der Bipontina in Zweibrücken mit den Büchereistellen Koblenz und Neustadt zu einer Sicht verschmolzen.

    Abstract
    Seit einigen Jahren ist der Begriff "Access" oder "Zugang" in aller Munde. Er bezieht sich auf den Zugang zu Informationsressourcen im World Wide Web und stellt eine zentrale Voraussetzung für den Erfolg oder Misserfolg in der modernen Gesellschaft dar. Viele Lebensbereiche sind auf einen ungehinderten Zugang zu digitalen Ressourcen angewiesen. Für ein Wirtschaftsunternehmen ist es im 21. Jahrhundert nicht mehr nur wichtig, über traditionelle Produktionsfaktoren, wie Maschinen oder Kapital, zu verfügen, von gleicher Bedeutung ist der Zugang auf Informationen, die intern und extern zur Verfügung stehen, und die Grundlage für ein umfassendes Wissensmanagement bilden. Damit kann der Innovationsprozess beschleunigt und das eigene Risiko vermindert werden, beispielsweise wenn bei der Produktentwicklung die Zeit bis zur Markteinführung verringert und damit ein wesentlicher Vorteil gegenüber den Konkurrenten erzielt wird. Auch die Welt der Wissenschaft hat sich in den letzten Jahrzehnten sehr verändert. Das Interesse von Wissenschaftlern ist nicht auf ihre jeweilige eigene nationale und kulturelle Umgebung beschränkt. Sie benötigen Informationen über Dokumente und Daten aus der ganzen Welt. Gleichzeitig wollen sie die eigenen Forschungsergebnisse in der internationalen Forschungsgemeinschaft zur Diskussion stellen. Schließlich ist der Zugang zu digitalen und konventionellen Ressourcen eine Voraussetzung für den Erfolg in dynamischen und global agierenden Gesellschaften und Systemen. Diese sind davon abhängig, dass Wissen ständig neu generiert und organisiert wird, und propagieren das lebenslange Lernen. Das Konzept des lebenslangen Lernens richtet sich an den Einzelnen, der seine Informationskompetenz ständig erweitern soll. Dadurch wird das Bedürfnis nach Bildungsangeboten im weitesten Sinne und folglich nach einem ungehinderten Zugang zu ihnen geweckt. All dies zeigt, dass ein reibungsloser Metadatenaustausch auf der Grundlage von sprachraumübergreifenden Standards eine wichtige Voraussetzung für Erfolge in ganz unterschiedlichen Bereichen ist. Daraus erwachsen wichtige Aufgaben für Bibliothekarinnen und Bibliothekare, die Daten über Dokumente bereitstellen und den Nachweis und Zugang zu ihnen garantieren. Deutschsprachige und ausländische Bibliotheken verwenden derzeit noch unterschiedliche Standards bei der Speicherung und dem Austausch von Katalogdaten. Während in Deutschland und Österreich das Maschinelle Austauschformat für Bibliotheken MAB2 verwendet wird, ist das Format Machine Readable Cataloguing MARC 21 der weltweit am weitesten verbreitete Standard.

    In weiterer Folge berichtet sie über die Stellungnahmen zu Part 1 - hier werden keine Hindernisse für eine Umsetzung gesehen. Bei Chapter 6-7 wurde festgehalten, dass die Angaben für Verweisungen zu allgemein gehalten wären und Verbünde schwer mit Kann-Bestimmungen umgehen könnten. Eine Begrenzung auf drei Autoren sei außerdem nicht mehr zeitgemäß. Die RDA-Deutsch soll wie folgt aussehen: - modularer Aufbau - Web-Produkt - Regeln für formale und inhaltliche Erschließung - verbundübergreifende Anwendungsrichtlinien Als vierte Vortragende gab Frau Christine Hengel einen Bericht zu den "Neuen Wegen" der Normdaten. Basis für die RDA ist ein konzeptionelles Modell für Normdaten, das von der IFLA-Arbeitsgruppe FRANAR erarbeitet wird. Dieses soll 2007 abgeschlossen sein. - Es wird gemeinsame Regeln für die Ansetzung von Personen und Körperschaften geben - sie beschäftigen sich mit: Normieren, Identifizieren, Anreichern, Sucheinstiegen. - Die neuen Regeln für die Ansetzung von Personen in den PND und SWD werden in die RDA einfließen - Es soll zu einer einheitliche Anwendung von kompatiblen Datenmodellen für die Bereiche Bibliotheken, Archive, Dokumentationen und Museen kommen - Forderung einer Online-Kommunikation mit Normdaten: dazu muss sich der Teilnehmerkreis von den Redaktionen bis hin zum Katalog stark erweitern. Das neue Redaktionsverfahren soll ab Mitte 2007 für die PND zum Einsatz kommen. Im Anschluss daran für die GKD. In der zweiten Hälfte des Jahres 2007 ist der Umstieg auf MARC21 geplant. Insgesamt war die Veranstaltung zu Recht schwach besucht; es gab wenig Neues, kaum Überraschendes und daher auch keine wirklich anregende Diskussion."
