    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
    Describes the Intelligent Literature Search Assistant (ILSA) which demonstrates the possibilities of a fully automated cataloguing workbench in an object orientated environment. Although developed with OPAC users in mind, it can be very useful to cataloguers in aiding both classification and subject heading access. Also describes work done at the University of Strathclyde in the area of machine learning and knowledge based systems, the Structured Information Management: Processing and Retrieval project (SIMPR). Advocates the use of uncontrolled vocabulary headings in conjunction with systems like ILSA, a layered approach rather than direct first point access, in order to make subject cataloguing easier and more relevant and the subject catalogue more useful to others

    Abstract
    Vom verflixten siebten Jahr kann man in Bregenz bisher nicht sprechen, im Gegenteil: Die Vorarlberger Landesbibliothek (VLB) hat kurz vor Ostern 2008 ihr 100.000. Inhaltsverzeichnis mit intelligentCAPTURE gescannt. Damit ist der Katalogeintrag von etwa 70 Prozent des betroffenen Freihandbestandes und sämtlicher Neuzugänge ab 2002 zusätzlich mit dem Inhaltsverzeichnis und zum Teil mit der Abbildung des Buchdeckels versehen. Die derzeitige Durchsatzrate beträgt pro Jahr 30.000 bibliographische Einheiten bei einem Personaleinsatz von 40 Stunden pro Woche. Die vollständige Erschließung des Buchbestandes in der Freihandaufstellung ist in Reichweite; ganz ohne Fördermittel im laufenden Betrieb; eine schlanke Lösung sowohl organisatorisch als auch finanziell. Da im Rahmen der Zusammenarbeit mit dandelon.com inzwischen weitere Bibliotheken in einem elegant gelösten Arbeitsablauf kooperativ erschließen, können wir bei Neuerscheinungen bereits die Hälfte als Fremddaten übernehmen. Die VLB hat mit der Digitalisierung, OCR-Konvertierung und maschinellen Indexierung von Inhaltsverzeichnissen und dem mehrsprachigen, semantischen Retrieval in der Suchmaschine dandelon.com zusammen mit der Firma AGI. Information Management Consultants Impulse im Bibliothekswesen gesetzt. Wer 2002 noch bezweifelte, dass dieser Ansatz erfolgreich sein wurde, wurde inzwischen eines Besseren belehrt. Zu offensichtlich ist der Mehrwert, den allein die Moglichkeit der entscheidend verbesserten Relevanzbeurteilung uber den OPAC bietet (http://vlb-katalog.vorarlberg.de). Er erfordert von einer zeitgemasen Bibliothek geradezu das Angebot solcher Zusatzinformationen. Aber die Anreicherung mit den Angaben aus den Inhaltsverzeichnissen bieten weit mehr, denn es entsteht durch die maschinelle Indexierung eine vollig neue Dimension an Retrievalmoglichkeiten. Die vollständige Erfassung unseres Bestandes war immer erklärtes Ziel unseres Projektes, weil wir gesehen haben, dass wir den Nutzern dadurch einen erheblichen Zusatznutzen bieten können, der in einem unbeschreiblich günstigen Verhältnis zum personellen und finanziellen Einsatz steht. Damit, dass wir dieses Ziel so schnell erreichen könnten, hatten wir nicht gerechnet.

    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
    Reports results of research into the feasibility of using OCR scanner technology to capture contents pages of collective monographs and to extract the bibliographic information of each individual work and process this using a standardized language, such as SGML, for tagging electronic documents. By this means, data can be used as electronic information or stored in OPACs, thus providing additional access points. Outlines a pilot system to test the initial hypotheses, show the feasibility of achieving the suggested goals and develop the tasks required for them to be carried out as automatically as possible

    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
    Bibliotheken sind nicht chaotische Sammlungen von Medien, sondern werden stets als Information-Retrieval-Systeme implementiert, denn das Wiederfinden bei exakten und vor allem bei vagen Anfragen ist von Anfang an das Sammlungsziel. Niemand kennt zum Zeitpunkt der Sammlung die Fragestellung, die einen zukünftigen Benutzer zu diesem Medium führen wird. Die Art der Sammlungsorganisation bestimmt in hohem Maße die zukünftig mögliche Antwortmenge und deren informatorische Qualität. Der Siegeszug der digitalen Information-Retrieval-Systeme im Internet hat in den letzten zehn Jahren Erwartungen und Märkte geschaffen, die weder Karteikarten, noch deren digitales Ebenbild, die heutigen Bibliotheksmanagement-Systeme befriedigen können. Es genügt nicht mehr, dass Google und andere kostenlos das aufsammeln und nachweisen, was im Internet frei zugänglich ist. Alte, noch »marktfähige« Inhalte werden neu aufbereitet, mit neuen Inhalten kombiniert, um neue Geschäftsfelder zu schaffen. Es geht um Verdrängung und Neuverteilung, und die älteren Inhalte der Bibliotheken sind meist noch hinreichend »marktfähig«.
