    Abstract
    Myriad new information resources are available to contemporary library users. While print remains the foundation of most collections, libraries are also beginning to provide access to an array of bibliographic, numeric, and full-text databases. As more and more information is produced in electronic form and presented at computer workstations, the library catalog is being given an expanded role. The expanded catalog will play a crucial part in organizing information in electronic libraries, and in providing navigational assistance to library users. Like the traditional card catalog, the expanded catalog will not only lead to specific items or groups of sources, but also will provide connections to related materials. These connections will uses standard data elements to link the results of a search in one database with related material in another. For example, links will show local library holdings of sources in citation databases. Cornell University's Mann Library serves the College of Agriculture and Life Sciences, the College of Human Ecology, and the Division of Biological Sciences. As part of electronic library development, Mann staff have been analyzing issues involved in making it possible for Agricola and BIOSIS users to see, automatically, which of their retrieved citations are from sources available in the Cornell libraries. Samples of citations from Agricola and BIOSIS were drawn, and data elements present in these records were compared with bibliographic records of the library's holdings. In some cases, links would be provided by ISSNs. The study shows, however, that the presence of standard identifiers such as ISSN, USBN, or CODEN cannot be assumed, and other linking algorithms must be developed. This article presents study results, provides an overview of several linking systems, and identifies some of the difficulties caused by lack of standardization between different bibliographic databases. It is clear that the concept of an expanded catalog will require not only links between information resources but agreements among information professionals on standard data elements.

    Abstract
    Kurz nach 11 Uhr erscheint ein seltsamer Mensch am InfoDesk der Universitätsbibliothek und spricht die diensthabende Bibliothekarin an: "Frosch!". Mh, was meint der? Sonst sagt er nichts. Will er sich vorstellen? Herr Frosch? Wurde er im Eingangsbereich von einem Frosch erschreckt, der sich zufällig dorthin verirrte? Sucht er Literatur zu Fröschen? Märchen, mit dem Froschkönig? Will er Froschschenkel zum Mittagessen zubereiten? Ein Erstsemester, der in Biologie sich mit dem Tier befasst? Frosch als Fresser oder als gefressen werden? Ist das etwa der Autor Karl Frosch oder sucht er Literatur von diesem? Ein der Sprache nicht ganz mächtiger Ausländer? Ein Verrückter? Mh, Alter, Geschlecht, Kleidung, Sprache, Gestik - all dies wird schnell durchgeprüft. Ganz so kurz, kann man doch eine Dipl.-Bibl. nicht so einfach ansprechen. Unverschämt! ... Ungewöhnlich? Keineswegs, ist dies doch unsere normale Art, sich mit Suchmaschinen und OPACs zu unterhalten. Ebenso wenig wie eine Bibliothekarin hier eine zufriedenstellende Antwort bieten kann, weiß auch keine Suchmaschine, was das Anliegen dieser Person ist. Weit schneller als die Bibliothekarin kann sie aber in ihrem Index das Suchwort aufspüren und eine Treffermenge vermelden. Der Schlitz der Suchmaschine hat im Gegensatz zum "Schlitz" der Bibliothek, dem InfoDesk, keine Augen und Ohren, hat kein stimulierendes Lächeln, die Frage weiter erläutern zu lassen.

    Abstract
    Contents enhancement of catalog records may increase access to books in collections and aid in effective resource sharing by providing more detailed descriptions about library holdings in the catalog. A sample of monographs in San Diego State Univ. Library was studied to determine the extent to which information in books from parts of the collection could be represented better by content notes, and to determine how much of this information has subject or analytical applications. The study revealed that approximately 23% of the books contain discrete content information not already represented in catalog records that could be added. Of those, 52% would be citation-based enhancements and 48% would be subject-based. Nearly 65% would require fewer than 25 enhancements, with an average of 8.03 enhancements per book for the total population

    Abstract
    From a logical point of view, an OPAC is an inventory with indexes. Inventories can be accumulated and the indexes merged. However, in most merged catalogues not all documents have the same subject indexing and a number of documents are indexed by more than one system. In practice, a merged catalogue also contains descriptions without subject indexing. To augment the situation four methods are used: searching with title keywords, mapping and switching, acceptance of descriptions indexed in a given way only, and »citation pearl growing«. The last method uses all available subject indicators by using subject indicators present in relevant descriptions found by already known indicators. This method can also be of help in mapping and switching.

    Abstract
    Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved

    Abstract
    Experimental evidence suggests that enhancing the subject content of OPAC records can improve retrieval performance. This is based on the use of natural language index terms derived from the table of contents and back-of-the-book index of documents. The research reported here investigates the alternative approach of translating these natural language terms into controlled vocabulary. Subject queries were collected by interview at the catalogue, and indexing of the queries demonstrated the impressive ability of PRECIS, and to a lesser extent LCSH, to represent users' information needs. DDC performed poorly in this respect. The assumption was made that an index language adequately specific to represent users' queries should be adequate to represent document contents. Searches were carried out on three test databases, and both natural language and PRECIS enhancement of MARC records increased the number of relevant documents found, with PRECIS showing the better performance. However, with weak stemming the advantage of PRECIS was lost. Consideration must also be given to the potential advantages of controlled vocabulary, over and above basic retrieval performance measures

    Abstract
    In 1986, all titles added to the collection at the Australian Defence Force Academy Library, are processed through their OPAC via a subject enhancement procedure (ESP). The procedure used for subject enhancement is based on the techniques developed by P.A. Atherton and B. Settel during the Subject Access Project at Syracuse Univ., 1977. Terms are selected from contents pages or the index of the book, depending on whether the terms are content bearing, and whether the terms refer to 5 or more pages of text. This results in the addition of an average of 73 words or 20 phrases to each MARC record. The terms are keyed into the MARC field 653 using in house modifications of the library's URICA system

    Abstract
    Die ETH-Bibliothek bietet seit Anfang des Jahres 2006 ihre Dienstleistung "Abstract / Index" in erweiterter Form an (http://www.ethbib.ethz.ch/abstract /abstract.html). Somit können zum gegenwärtigen Zeitpunkt für mehr als 50.000 im Katalog des Schweizer Bibliothekenverbundes NEBIS nachgewiesene Bücher, ergänzende inhaltliche Informationen abgerufen werden. Hierzu gehören Abstracts, Inhaltsverzeichnisse sowie Angaben zu Autorinnen und Autoren. Die Recherche erfolgt über die Link-Verknüpfung "Abstract / Index" im Katalog. Da es sich bei der ETH-Bibliothek um eine reine Magazinbibliothek handelt, wird mit diesen Zusatzinformationen den Benutzerinnen und Benutzern der Bibliothek die Vorselektion der Bücher und somit eine gezieltere Auswahl wesentlich erleichtert. Bücher, die von vornherein nicht von Interesse sind, kommen deshalb erst gar nicht in den Ausleihprozess und stehen somit anderen Nutzern unmittelbar zur Verfügung. Grundsätzlich gibt es zwei Möglichkeiten, die Links abzufragen: Bei der Abfrage in der Katalogdatenbank kann in der Vollanzeige eines Titels der Link "Abstract / Index" angeklickt werden, worauf sich ein Pop-up-Fenster mit den zusätzlichen Informationen öffnet. Bei der natürlichsprachigen Abfrage können die Suchergebnisse um die Funktion "Abstract / Index" erweitert werden. Finden sich die gesuchten Begriffe dann in den verlinkten Informationstexten, so erhöht sich die Anzahl der Treffer. Technisch handelt es sich bei diesem Angebot um eine in das Bibliothekssystem Aleph integrierte Lösung, wobei die zusätzlichen Informationen in einer parallel zum NEBIS-Katalog geführten Datenbank gespeichert sind. In diese separate Datenbank werden gleichzeitig größere Datenmengen eingespeist, die zum einen von den Verlagen Wiley und Springer zu Verfügung gestellt werden. Weiter geht es um eine beträchtliche Anzahl von Daten, die die ETH-Bibliothek selbst erfasst. Die zu den Textinformationen gehörenden Datensätze im Katalog werden anhand der ISBN identifiziert und mit einem MARC-Feld 856 versehen. Über dieses Link-Feld können die Zusatzinformationen dann dem entsprechenden Datensatz im Katalog zugeordnet werden. Naturgemäss ist dieses Dienstleistungsangebot ein "Work in progress", was bedeutet, dass der mittlerweile vorhandene Datenpool an Abstracts und anderen Informationen fortlaufend ausgebaut wird. So wird etwa bis Ende des Jahres 2007 das Gros der in der ETH-Bibliothek vorhandenen Bücher mit Erscheinungsjahr 1995 und jünger nachträglich bearbeitet und in die Katalogdatenbank integriert. Hierzu parallel wird die Aufnahme der Neuzugänge kontinuierlich weitergeführt. Zusammen werden somit zukünftig etwa 1.000 neue Abstracts pro Monat generiert.

    Abstract
    The author collected information about tables of content and index terms in 125 books borrowed by patrons in a medium-sized academic library. To learn how useful the term would be as subject terms in a library catalog, he determined which of these terms were the same as the words used by the patrons to describe the books. For 72,4% of the books assigned LCSH, the patron's term matched the LCheading. The patron's term matched the table of contents term for (1,3% of the books with tables of contents. If the catalog had included terms from the tables of contents and the indexes in addition to the LCSH, the success rate would have been 97,3%. One problem in using terms from books in a library catalog is that many books lack indexes and/or tables of context

    Abstract
    Zur Bewältigung dieser Menge an Artikeldaten kommt im IAI die Software C-3 der ImageWare Components GmbH zum Einsatz, die es ermöglicht, die formale Erschließung in einem größtenteils automatisierten Geschäftsgang durchzuführen. In den einzelnen Modulen von C-3 erfolgt die automatische Erkennung der Titel-, Autoren- und Seitenzahlinformationen in den gescannten Inhaltsverzeichnissen sowie deren automatische Indexierung und Konversion in Katalogisate. An den Indexierungsarbeitsplätzen kommen normale Standard-PCs zum Einsatz, über die auf die Auftragsverwaltung des zentralen C-3 Periodikaservers per Browser zugegriffen wird. Die C-3 Software besteht aus den Programmmodulen C-3 Template und C-3 Index. In C-3 Template werden einmalig für jeden Zeitschriftentitel die Struktur der Inhaltsverzeichnisse (Interpretationstyp Regel, Tabelle oder Freiform), die Abfolge von Aufsatztitel, Autoren und Seitenzahlen sowie die Schriftattribute (fett, kursiv etc.) der bibliografischen Daten festgelegt. Auf Basis dieser Templatedefinition werden die Scans der jeweiligen Inhaltsverzeichnisse im C-3 Index Modul mit der OCR Software Abbyy Fine Reader so erkannt, dass die bibliografischen Informationen der einzelnen Aufsätze bereits kategorisiert und aufsatzweise separiert ausgegeben werden. Die dabei erzeugten Daten können, sofern erforderlich, noch während der Bearbeitung mit C-3 mit einer Reihe von integrierten Nachbearbeitungstools korrigiert und im Anschluss im XML-Format an den C-3 Periodikaserver exportiert werden. Automatische Konversionsroutinen erzeugen aus den xml-Dateien serverseitig Artikeldaten im Pica3-Format, die nach einer abschließenden Qualitätskontrolle in die Online Contents Datenbanken des GBV eingespielt werden.
