    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.

    Abstract
    Describes the shortcomings of search engines for the WWW comparing their current capabilities to those of the first generation CD-ROM products. Some allow phrase searching and most are improving their Boolean searching. Few allow truncation, wild cards or nested logic. They are stateless, losing previous search criteria. Unlike the indexing and classification systems for today's CD-ROMs, those for Web pages are random, unstructured and of variable quality. Considers that at best Web search engines can only offer free text searching. Discusses whether automatic data classification systems such as Infoseek Ultra can overcome the haphazard nature of the Web with neural network technology, and whether Boolean search techniques may be redundant when replaced by technology such as the Euroferret search engine. However, artificial intelligence is rarely successful on huge, varied databases. Relevance ranking and automatic query expansion still use the same simple inverted indexes. Most Web search engines do nothing more than word counting. Further complications arise with foreign languages

    Abstract
    Results of a survey of North Carolina Libraries revealed that of 91 respondents, 29 had on-line catalogues. Of the libraries with on-line catalogues, 11 used the Dewey Decimal Classification (DDC). Survey findings indicate that the DDC has limited use in on-line searching today.
