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.
