    Abstract
    This paper discusses constraints in knowledge organisation for information retrieval introduced by the difficulty of separating logical views of data, information, concepts and their relationships, from the physical means by which we seek to implement retrieval systems. A parallel is drawn between the move from enumerated to faceted classification and the emergence of relational database management systems to replace those adopting a hierarchical structure. This parallel suggests a convergence of ideas which have been, to a large extent, developed independently. The role of post-coordinated retrieval systems and thesauri is then examined before an interface design (HIBROWSE - a High resolution Interface for BROWsing and SEarching databases), is described which brings together the principles of faceted classification and increases the bandwidth of interaction through view-based searching.

    Abstract
    Purpose - This short note seeks to respond to Hjørland and Pederson's paper "A substantive theory of classification for information retrieval" which starts from Sparck Jones's, "Some thoughts on classification for retrieval", originally published in 1970. Design/methodology/approach - The note comments on the context in which the 1970 paper was written, and on Hjørland and Pedersen's views, emphasising the need for well-grounded classification theory and application. Findings - The note maintains that text-based, a posteriori, classification, as increasingly found in applications, is likely to be more useful, in general, than a priori classification. Originality/value - The note elaborates on points made in a well-received earlier paper.

    Abstract
    The application of classification schemes and thesauri to improve online information retrieval can be traced back to the beginnings of online searching itself, but the true potential for using knowledge structures in the user interface has yet to be realized. View-based searching seeks to exploit the classified arrangements in thesauri and existing classification schemes to improve the performance of such systems. HIBROWSE for EMBASE is a system which demonstrates the power of applying an approach to information retrieval which is strongly related to faceted classification. It does this by employing a point a click user interface with mutually constraining views utilising knowledge structure hierarchies for both query specification and the presentation of results. The relevance of this approach to library OPACs is discussed in the context of the digital library, concluding that out legacy of research in classification and indexing is more relevant than ever in the design of systems to cope with the problems of information access

    Abstract
    This paper examines issues relating to the use of the Dewey Decimal Classification (DDC) in a future development of view-based searching to Online Public Access Catalogues (OPAC). View-based searching systems, exercising the principles of fully faceted classification techniques for both bibliographic and corporate database retrieval applications, are now being applied to utilise Dewey concept hierarchies in a University OPAC. Issues of efficiency and effectiveness in the evolving organisation and classification of information within libraries are examined to explain why fully faceted classification schemes have yet to realise their full potential in libraries. The key to their application in OPACs lies in the use of faceted classification as pre-coordinated indexing and abandoning the single dimension relative ordering of books on shelves. The need to maintain a single relative physical position on a bookshelf is the major source of complexity in classification. Extensive latent benefits will be realised when systematic subject arrangements, providing alternative views onto OPACs, are coupled to view-based browser and search techniques. Time and effort will be saved, and effectiveness increased, as rapid access is provided to the most appropriate information to satisfy the needs of the user. A future for Dewey Classification divorced from its decimal notation is anticipated

    Abstract
    The scatter of items dealing with similar concepts through the physical library is a consequence of a classification process that produces a single notation to enable relative location. Compromises must be made to place an item where it is most appropriate for a given user community. No such compromise is needed with a digital library where the item can be considered to occupy a very large number of relative locations, as befits the needs of the user. Interfaces to these digital libraries can reuse the knowledge structures of their physical counterparts yet still address the problem of scatter. View-based searching is an approach that takes advantage of the knowledge structures but addresses the problem of scatter by applying a facetted approach to information retrieval. This paper describes the most recent developments in the implementation of a view-based searching system for a University Library OPAC. The user interface exploits the knowledge structures in the Dewey Decimal Classification Scheme (DDC) in navigable views with implicit Boolean searching. DDC classifies multifaceted items by building a single relative code from components. These codes may already have been combined in the schedules or be built according to well-documented instructions. Rules can be applied to decode these numbers to provide codes for each additional facet. To enhance the retrieval power of the view-based searching system, multiple facet codes are being extracted through decomposition from single Dewey Class Codes. This paper presents the results of applying automatic decomposition in respect of Geographic Area and the creation of a view (by Geographic Area) for the full collection of over 250,000 library items. This is the first step in demonstrating how the problem of scatter of subject matter across the disciplines of the Dewey Decimal Classification and the physical library collection can be addressed through the use of facets and view-based searching

    Abstract
    Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

    Abstract
    Ab Januar 2006 wird Die Deutsche Bibliothek ein neues Webangebot mit dem Namen Melvil starten, das ein Ergebnis ihres Engagements für die DDC und das Projekt DDC Deutsch ist. Der angebotene Webservice basiert auf der Übersetzung der 22. Ausgabe der DDC, die im Oktober 2005 als Druckausgabe im K. G. Saur Verlag erscheint. Er bietet jedoch darüber hinausgehende Features, die den Klassifizierer bei seiner Arbeit unterstützen und erstmals eine verbale Recherche für Endnutzer über DDCerschlossene Titel ermöglichen. Der Webservice Melvil gliedert sich in drei Anwendungen: - MelvilClass, - MelvilSearch und - MelvilSoap.
