    "»Simplify your life«, heißt einer der großen Sachbuchbestseller der letzten Jahre. Dessen Quintessenz: In einer zusehends komplexer werdenden Welt sind Vereinfachungen (über)lebensnotwendig. Dies gilt für alle Lebensbereiche, in besonderem Maße aber für die Suche nach Informationen. Um Bibliotheksbenutzer an die von ihnen gewünschte Literatur heranzuführen, kann seitens der Bibliotheken sicher noch einiges an Vereinfachungsleistung erbracht werden - insbesondere dann, wenn der Benutzer sich bei der Suche nicht mit den Beständen seines nationalen Bibliothekssystems begnügt, sondern die Möglichkeit nutzt, weltweit online zu recherchieren. Eine Suche unter Zuhilfenahme von Titelstichwörtern bereitet heute nur wenig Kopfzerbrechen, ist aber oft unbefriedigend für die sachliche Suche. Leider gestaltet sich der hier deutlich zielführende Rückgriff auf Sacherschließungsdaten in der Praxis erheblich schwieriger. Der Benutzer ist mit einer Vielzahl unterschiedlicher Erschließungssysteme konfrontiert, die vielfach unverbunden nebeneinander existieren. Da die Bestände der weitaus meisten Bibliotheken heterogen erschlossen sind, müsste der Benutzer alle Erschließungsverfahren kennen und nacheinander anwenden, um sicherzustellen, dass ihm keine Informationen verloren gehen.
    An diesem Punkt setzt das neue Projekt CrissCross an, das gemeinsam von der Deutschen Nationalbibliothek (DNB) und der Fachhochschule Köln betrieben und von der Deutschen Forschungsgemeinschaft (DFG) gefördert wird. CrissCross schafft Verbindungslinien zwischen einigen besonders verbreiteten und bewährten Erschließungsinstrumenten: Der deutschsprachigen Schlagwortnormdatei (SWD), den besonders im angloamerikanischen Raum verbreiteten Library of Congress Subject Headings (LCSH), der französischen Dokumentationssprache Répertoire d'autorité-matière encyclopédique et alphabétique unifié (Rameau) und der Dewey Decimal Classification (DDC) als dem international am meisten verbreiteten Klassifikationssystem. CrissCross kann dabei auf zwei wichtigen Vorgängerprojekten aufbauen. Hier ist zum einen das ebenfalls von DNB und der Fachhochschule Köln gemeinsam betriebene Vorgängerprojekt »DDC Deutsch« zu nennen. Bereits während dessen Laufzeit war deutlich geworden, wie vorteilhaft sich eine Anreicherung des DDC-Registers mit dem Schlagwortbestand der SWD auf die Klassifikationspraxis auswirken könnte. Genau dieser Schritt wird nun vollzogen, wobei sich die Projektarbeit auf die Sachschlagwörter konzentriert - kein kleines Unterfangen, beläuft sich doch die Zahl der zurzeit in der SWD befindlichen Datensätze mit dem Indikator s auf über 154.000.
    Ein weiteres Fundament sind die Vorarbeiten aus dem gemeinsam von DNB, der Schweizerischen Landesbibliothek und anderen Partnern betriebenen Projekt Multilingual Access to Subjects (MACS). Im Rahmen von MACS wurden in größerem Umfang LCSH und Rameau-Datensätze miteinander verknüpft; einigen der dabei entstandenen Schlagwortpärchen wurde dabei bereits ein SWD-Äquivalent zugeordnet. Dreierverbindungen dieses Typs, erweitert um DDC-Notationen, werden auch im Rahmen von CrissCross entstehen. Die unterschiedliche Strukturierung der einzelnen Schlagwortsprachen sorgt allerdings für eine Vielzahl von Problemen, die das Projektteam bewältigen muss. Durch die Verlinkung der Schlagwortsprachen und die Verknüpfung mit der DDC erstellt CrissCross ein multilinguales verbales Recherchevokabular. Ungewöhnlich und innovativ ist dabei vor allem die Verbindung von verbaler und klassifikatorischer Sacherschließung, die zu einer bedeutenden Erweiterung der Recherchemöglichkeiten führen wird. Dies wird vor allem dann der Fall sein, wenn in Onlineumgebungen nutzbare Hilfsmittel wie das von der DNB zurzeit entwickelte Normdatenrecherchetool zur Verfügung stehen. In naher Zukunft wird der Nutzer dann bei seiner Suche auf eine Vielzahl unterschiedlich erschlossener Werke stoßen, ohne dass ihm die im Hintergrund vollzogene Auswertung von Normdaten bewusst sein muss. Er braucht im Grunde genommen überhaupt kein Vorwissen über Sacherschließungsinstrumente mitzubringen. »Simplify your search«, könnte das Motto dieser Vorgehensweise lauten. Die Nutzerfreundlichkeit der Bibliotheken wird durch den Einsatz derartiger Instrumente eine deutliche Steigerung erfahren. CrissCross wird seinen Teil dazu beitragen."

    Abstract
    New forms of man-machine interaction are becoming available that have great power for the delivery of information. But the scales of speed and capacity on which the computing machines operate demand new thoughts as to how information can be stored and retrieved. The objective of the discussion in this paper is to argue for a combination of natural-language processing and subject classification to be able to meet the demands

    Abstract
    The article describes the research done over a bibliographic database in order to show the impact the specificity of the knowledge organising tools may have on information retrieval (IR). For this purpose two multilingual Universal Decimal Classification (UDC) based thesauri having different degrees of specificity are considered. Issues of harmonising a classificatory structure with a thesaurus structure are introduced, and significant aspects of information retrieval in a multilingual environment are examined in an extensive manner. Aspects of complementarity are discussed with particular emphasis on the real impact produced on IR by alternative search facilities. Finally, a number of conclusions are formulated as they arise from the study.

    Abstract
    In the early 1990s, indexing with classification codes from the Universal Decimal Classification (UDC) in an academic library, going from traditional to automated routines in any and all its activities, suddenly proved insufficient. Under the circumstances of online searching, the possibilities offered by the new OPAC looked much more attractive to indexers and searchers alike. Therefore, a quick shift to indexing with UDC and keywords instead of UDC numbers alone was made. Currency, precision and, more importantly, user-friendliness were strong advantages offered by keyword indexing and searching. But the larger the dictionary of keywords, the more problematic the consequences an information scattering, given the lack of control an terms. The present paper describes the advantages of the UDC in indexing by presenting some of the devices it is provided with: subdivision by analogy, common and special auxiliaries, use of synthesis, and use of connecting symbols. The solution of indexing with both UDC notation and words from a thesaurus based an UDC was prompted by some other characteristics of the schedules: a semi-faceted classification system, hierarchical organisation, richness in terminology and consistency and control of notation. The methodology used in building the thesaurus is conceived according to the international standards (ISO 2788 and 5964) to which some principles have been added, giving the specific approach of harmonising a classification structure with that of a thesaurus. Compatibility and translatability issues are also considered and some problems arising from them are treated in detail. Most of the problems discussed are illustrated with examples.

    The aim of this initiative is to provide the users of online library catalogues and information gateways of cooperating libraries with a prototype for multilingual subject searching in online environment. Library collections of these libraries are large and without any doubt very valuable for researchers throughout Europe. What is needed is a standardized, authorized indexing and retrieval tool which would bring together all their catalogues and databases and enable multilingual subject searching. At the beginning of the project, a number of factors affecting subject indexing in current environment and cross-searching for subjects have been identified. These factors include - standardization of subject retrieval process and indexing and classification tools - subject retrieval methods - possibility of interoperability among different indexing and classification schemes - multilingualism issue - possibility to increase precision and recall trough Z39.50 protocol and its profiles and to apply authority control in subject retrieval process - need for cooperation
