    "»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
    The case under consideration is a project of building an interdisciplinary multilingual thesaurus (Romanian-English-French) starting from a list of indexing terms based on an abridged version of the Universal Decimal Classification (UDC). The resulting thesaurus is intended for public libraries for both indexing and searching purposes in bibliographic databases covering a wide range of topics but with a fairly low level of specificity. The problems encountered in such an approach fall into two groups: 1) concordance or compatibility problems in terms of the indexing languages considered (between a classification system and a thesaurus); 2) equivalence and, hence, translatability problems in terms of the natural languages involved. Additionally, the question of ambiguity given the co-occurrence of terms in more than one class, will be discussed with reference to homographs and polysemantic words. In a thesaurus with such a wide coverage yet with a low specificity level, the method adopted in the thesaurus construction was to provide as many lead-in terms as possible and post them up to the closest in meaning broader term in order to improve the recall ratio

    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.

    Abstract
    Czech authority file of topical terms is intended to form a base for multilingual controlled vocabulary. The aim of the proposal is to provide users of online library catalogues and internet services of cooperating institutions with an indexing and retrieval tool which enables multilingual and cross-domain searching ("one-stop" seamless searching). The goal of the project is to establish a multilingual subject approach to catalogues of participating libraries (Czechia, Croatia, Latvia, Lithuania, Macedonia, Slovakia, and Slovenia). In practice this means that a user in any of these countries would enter a query in his local language and receive hits from all the catalogues. The initiative is complying with the main goals currently defined by IFLA for the activity of Indexing and Classification Section, it means: Changing Roles of Subject Access Tools (Berlin), Implementation and Adaptation of Global Tools for Subject Access to Local Needs (Buenos Aires), and Cataloguing and Subject Tools for Global Access: International Partnerships (Oslo).
