    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
    Since Dec 86, the Australian Defence Force Academy (ADFA) library has been enriching bibliographic records by adding terms from either the contents pages or indexes of books. 40.000 records are now enriched, representing about 25% coverage of the ADFA database of 210.000 titles. Evaluates the retrieval effectiveness of the enriched data in an OPAC, in comparison with title and LCSH, using 90 topics from 6 different subject areas

    Abstract
    As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology

    Abstract
    Subject access plays an important part when plans are made for an on-line public access catalogue (OPAC). Therefore, current subject searching facilities in OPACs should be accessed carefully. These facilities include, amongst other things, phrase searching, keyword searching and class number retrieval. Users reaction have been instrumental in identifying certain shortcomings in subject access to OPACs. Points out certain shortcomings in subject access, as shown by a number of research projects undertaken during the past decade. Highlights aspects which could, in future, improve subject access in OPACs. This could be achieved by either enhancing content representation in the records within the OPAC data base or by enhancing the searchability and browsability of the OPAC. Considers whether the on-line catalogue will ever be a finished, perfect product, or achieve the universal, familiar uniformity experienced by users of the 20th century card catalogue.

    Abstract
    Ein weiterer Meilenstein beim Catalogue Enrichment ist die Kooperation zwischen dem Hochschulbibliothekszentrum NRW (hbz) und Springer Science+Business Media. Ziel der Kooperation ist eine Anreicherung der im hbz-Verbundbestand nachgewiesenen Springer-Titel um Inhalte wie Buchcover, Inhaltsverzeichnisse, Vorworte und Probekapitel.
    Content
    "»Die Anreicherung von Bibliothekskatalogen bedeutet zusätzliche Informationen für die Bibliotheksnutzer«, betont Hans Ollig; der Leiter des hbz. »Sie erhalten dadurch wichtige Orientierungs- und Entscheidungshilfen bei der Auswahl der Literatur.« Der Springer-Verlag lieferte dem hbz zunächst einen Grundbestand von 22.000 Objekten der Verlagsproduktion der letzten fünf Jahre. Daran schließen sich Ergänzungslieferungen an: Neue Titel des Verlags werden monatlich auf den Servern des hbz eingespielt. Technische Basis des Catalogue Enrichment sind das Verbundsystem Aleph, der hbz-Medienserver und die hbz-Suchmaschinentechnologie zur Präsentation der Daten. Zunächst sind die rund 17.000 im hbz-Verbundkatalog vorhandenen Springer-Titel in den Medienserver geladen und in der hbz-Verbunddatenbank verfügbar gemacht worden. Von dort aus werden sie in die lokalen Kataloge der Verbundbibliotheken und in den Dreiländerkatalog des hbz integriert. Die Daten werden soweit möglich volltextlich indexiert und können somit bei der Recherche direkt durchsucht werden. Die Kooperation mit Springer Science+Business Media ist erst der Anfang: Das hbz verhandelt bereits mit weiteren Verlagen und Datenanbietern über Kooperationen, um den Bibliotheken weiteren, über die traditionelle sachliche Erschließung hinausgehenden Mehrwert für ihre Kataloge bieten zu können,"

    Abstract
    Unter dem Stichwort Catalogue Enrichment läuft derzeit in Köln ein Projekt, in dessen Verlauf die Inhaltsverzeichnisse von 180.000 Büchern gescannt, mit einer Texterkennung als Volltext aufgearbeitet und schließlich in die verschiedenen Katalogsysteme eingespeist werden. Das Projekt startete am 1. September 2005 und soll vor Weihnachten abgeschlossen werden. Noch läuft das Unterfangen unter dem Arbeitstitel 180T-Projekt (für 180.000 Bücher). Einen endgültigen Titel wird das Projekt in einer späteren Phase bekommen, denn, wie Frau Gitmans von der Projektkoordination des hbz (Hochschulbibliothekszentrum des Landes Nordrhein-Westfalen) betont, es werde über die Fortsetzung des Catalogue Enrichments mit weiteren Partnerbibliotheken nachgedacht, so dass die Menge dann 180.000 Medien überschreite und ein neuer Titel gefunden werden müsse.

    Abstract
    Angesichts der Allgegenwart von Amazon und Google sowie von zunehmend verwöhnten Internetnutzern sind die Bibliotheken gefordert, das Feld der Innovation nicht allein kommerziellen Anbietern zu überlassen. Das hbz hat in einer Kooperation mit der USB Köln und der ZB MED ein erfolgreiches Projekt zum Catalogue Enrichment gestartet, das in diesem Umfang in Deutschland bisher einmalig ist und für weitere Vorhaben richtungsweisend sein könnte.

    Abstract
    Warum Catalogue Enrichment? Welcher Literatursuchende hat sich noch nicht die Frage gestellt, ob die im Rahmen einer Katalogrecherche ermittelten Titel wirklich relevante Informationen zu einem Thema enthalten? Wer hat sich noch nicht darüber geärgert, eine Literatursuche von zuhause oder einem Arbeitsplatz in der Universität durchgeführt zu haben, dann wegen des im Katalog gefundenen Titels extra in die Bibliothek gegangen zu sein, um dort feststellen zu müssen, dass das betreffende Buch einen ganz anderen als den erhofften Inhalt hat? Eine Lösung für dieses Problem bietet die Anreicherung der Kataloge mit Inhaltsverzeichnissen, Klappentexten und anderen Informationen. Die neuen, zusätzlichen Informationen dienen als wichtige Orientierungs- und Entscheidungshilfen bei der Auswahl der Literatur. Sie erlauben oft wesentlich zuverlässiger als der Buchtitel eine Einschätzung, ob ein Buch für das Thema, zu dem Literatur gesucht wird, relevant ist oder nicht. Das gilt insbesondere für Sammelwerke (Kongressberichte, Festschriften, u. a.), die mehrere, von verschiedenen Autorinnen und Autoren geschriebene Aufsätze enthalten und für Monographien mit nicht aussagekräftigen Titeln. Die Serviceleistung Catalogue Enrichment eröffnet in der Regel zwei neue Möglichkeiten bei der Katalogrecherche: Zum einen kann über die Vollanzeige im Katalog über einen Link das Inhaltsverzeichnis direkt als pdf-File aufgerufen werden. Anhand dieses Inhaltsverzeichnisses kann dann unmittelbar am PC überprüft werden, ob der Titel tatsächlich den Erwartungen entspricht. Des Weiteren sind die in den Inhaltsverzeichnissen enthaltenen Begriffe im Katalog recherchierbar. Durch diese zusätzlichen Sucheinstiege erhöht sich die Wahrscheinlichkeit, relevante Treffer zu erzielen. Die Anreicherung des Kataloges mit den Images von Inhaltsverzeichnissen und den entsprechenden (durch OCR suchbaren) Indexaten ermöglicht, gerade jenen Teil der Bücher zu durchsuchen, der neben der Haupttitelseite die wichtigste Quelle für rechercherelevante Begriffe darstellt. Durch die Anreicherung der Titeldaten wird der Nutzerkomfort erhöht und der bisher bestehende "Retrieval-Mangel"' ganz entscheidend reduziert. Das alte Dilemma, dass Kundinnen und Kunden einer Bibliothek das, was sie suchen, nicht finden. obgleich es vorhanden ist. kann somit minimiert werden Die auch unter wirtschaftlichen Gesichtspunkten nicht vertretbare Nichtnutzung vorhandener Bestände und die Veranlassung letztlich unnötiger Magazinbestellungen oder teurer Fernleihen gehören damit bald der Vergangenheit an.
    . . . Perspektive Das Projekt Catalogue Enrichment des Landes Nordrhein-Westfalen wird 2008 mit Unterstützung des Ministeriums für Innovation, Wissenschaft, Forschung und Technologie fortgeführt werden. Das bisherige Ergebnis ist in quantitativer und qualitativer Hinsicht sicherlich einmalig in einem deutschen Bibliotheksverbund und in jeder Hinsicht richtungsweisend. Ein Ziel des Projektes, durch frühe und überzeugende Strahlkraft auf nationaler Ebene eine Diversifikation der Scanmethode und Scanqualität sowie Doppelarbeit zu verhindern bzw. zu minimieren, wurde jedoch leider nicht erreicht. Die im Bibliothekswesen ja durchaus übliche "Postkoordination" wird zurzeit von den Verbünden unter Einschluss der demnächst mit dem aktiven Anreichern von Titeldaten beginnenden Deutschen Nationalbibliothek intensiv betrieben. Es ist zu wünschen, dass diese Kooperation erfolgreich verläuft. Ziel muss sein, dass jedes Inhaltsverzeichnis in Deutschland qualitativ hochwertig nur einmal gescannt und im Anschluss daran allen anderen Bibliotheken zeitnah und kostenlos zur Verfügung gestellt wird.

    Abstract
    Describes an approach to indexing which seeks to eliminate the shortcoming of the representation of information in existing bibliographic catalogues: Subject Access Project (SAP) indexing which has been used successfully at Lund University and elsewhere. Existing catalogue records have been enriched with terms selected from lists of contents and indexes in books thus facilitating access to specific parts of documents and smaller semantic entites such as chapter titles, subject titles and data in graphic or tabulated form available in a wide range of publications

    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
    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
