    Abstract
    The concept of c-space is proposed as a visualization schema relating containers of content to cataloging surrogates and classification structures. Possible applications of keyword vector clusters within c-space could include improved retrieval rates through the use of captioning within visual hierarchies, tracings of semantic bleeding among subclasses, and access to buried knowledge within subject-neutral publication containers. The Scholastica Project is described as one example, following a tradition of research dating back to the 1980's. Preliminary focus group assessment indicates that this type of classification rendering may offer digital library searchers enriched entry strategies and an expanded range of re-entry vocabularies. Those of us who work in traditional libraries typically assume that our systems of classification: Library of Congress Classification (LCC) and Dewey Decimal Classification (DDC), are descriptive rather than prescriptive. In other words, LCC classes and subclasses approximate natural groupings of texts that reflect an underlying order of knowledge, rather than arbitrary categories prescribed by librarians to facilitate efficient shelving. Philosophical support for this assumption has traditionally been found in a number of places, from the archetypal tree of knowledge, to Aristotelian categories, to the concept of discursive formations proposed by Michel Foucault. Gary P. Radford has elegantly described an encounter with Foucault's discursive formations in the traditional library setting: "Just by looking at the titles on the spines, you can see how the books cluster together...You can identify those books that seem to form the heart of the discursive formation and those books that reside on the margins. Moving along the shelves, you see those books that tend to bleed over into other classifications and that straddle multiple discursive formations. You can physically and sensually experience...those points that feel like state borders or national boundaries, those points where one subject ends and another begins, or those magical places where one subject has morphed into another..."

    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.

    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
    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
    To determine the potential benefits of providing classified displays of search results, we analyzed the classification features of the OCLC NetFirst database using criteria developed by the Subject Analysis Committee (SAC) subcommittee an Metadata and Classification. We also studied NetFirst search logs to better understand how the classification-based searching and limiting functions implemented in the system are being used. Our findings suggest that to increase the use of classification-based features in systems for general users, classificatory functions must be well integrated with the basic search and display functions.

    Abstract
    In the DDC Online Project, subject searching and browsing of DDC schedules and relative index were featured in an experimental online catalog. The effectiveness of this DDC in an online catalog was tested in online retrieval experiments at four participating libraries. These experiments provided data for analyses of subject searchers' use of a library classification in the information retrieval environment of an online catalog. Recommendations were provided for the enhancement of bibliographic records, online catalogs, and online cataloging systems with a library classification. In this paper, subject searchers' use of the subject outline search capability of the experimental online catalog is described. This capability was unique to the experimental online catalog and all other online catalogs, because it referred searchers to online displays of the classification schedules based on their entry of subject terms. Failure analyses of subject outline searches demonstrated its specific strenghts and weaknesses. Users' postsearch interview comments highlighted their experiences and their satisfaction with this search. Based on the failure analyses and users' interview comments, recommendations are provided for the improvement of the subject outline search in online catalogs.

    Abstract
    This paper documents the continuing relevance of facet analysis as a technique for searching and organising WWW based materials. The 2 approaches underlying WWW searching and indexing - word and concept based indexing - are outlined. It is argued that facet analysis as an a posteriori approach to classification using words from the subject field as the concept terms in the classification derived represents an excellent approach to searching and organising the results of WWW searches using either search engines or search directories. Finally it is argued that the underlying philosophy of facet analysis is better suited to the disparate nature of WWW resources and searchers than the assumptions of contemporaray IR research.
