    Abstract
    The 'facet-space' approach for accessing document records organized by faceted classifications is described. The interface gives users detailed control over the facet display and it makes use of color to reduce the number of windows which need to be presented. The interface supports searching. A cluster analysis is described for organizing search return lists based on facets distances. The implementation is applied to 1381 summaries of computer science dissertations as organised by the ACM Computing Reviews classification system

    Abstract
    Two library classification system interfaces have been implemented for navigating and searching large collections of document and book records. One interface allows the user to browse book records organized by the DDC hierarchy. A Book Shelf display reflects the facet position in the classification hierarchy during browsing, and it dynamically updates to reflect search hits and attribute selections. The other interface provides access to records describing computer science documents classified by the ACM Computing Reviews (CR) system. The CR classification system is a type of faceted classification in which documents can appear at several points in the hierarchy. These two interfaces demonstrate that classification structure can be effectively utilized for organizing digital libraries and, potentiall, collections of Internet-wide information services

    Abstract
    Two interfaces are described for navigating large collections of document and book records. An Online Public Access Catalog interface uses a classification hierarchy to facilitate browsing and searching. The system has been implemented and currently runs with over 50,000 book records. Interface widgets allow the hierarchy to be displayed and traversed easily. For example, the Book Shelf dynamically updates itself to reflect searches and attribute selections. A second interface, not yet fully implemented, allows access to the ACM Computing Reviews classification. By browsing a graphic structure such as a classification hierarchy or term network, the user can select or negate terms to incrementally enlarge or refine the query. A number of systems have been proposed that utilise this type of interface: Allen [1] allows users to traverse sections of a classification hierarchy that are adjacent to documents retrieved by a search; Doyle [6] discusses a graph-based interactive browsing environment; Croft [4] extends Doyle's termbased graph with vertices and edges representing individual documents and their degrees of similarity to each other; Frei and Jauslin [7] use tree structures to represent both system command menus and document indexing structures; and Godin [10] and Pedersen [16] model a collection's conceptual structure with termdocument lattices.
