    Abstract
    Broughton is one of the key people working on the second edition of the Bliss Bibliographic Classification (BC2). Her article has a brief, informative history of facets, then discusses semantic vs. syntactic relationships, standard facets used by Ranganathan and the Classification Research Group, facet analysis and citation order, and how to build subject indexes out of faceted classifications, all with occasional reference to digital environments and hypertext, but never with any specifics. It concludes by saying of faceted classification that the "capacity which it has to create highly sophisticated structures for the accommodation of complex objects suggests that it is worth investigation as an organizational tool for digital materials, and that the results of such investigation would be knowledge structures of unparalleled utility and elegance." How to build them is left to the reader, but this article provides an excellent starting point. It includes an example that shows how general concepts can be applied to a small set of documents and subjects, and how terms can be adapted to suit the material and users

    Abstract
    The Bliss Bibliographic Classification is the only example of a fully faceted general classification scheme in the Western world. Although it is the object of much interest as a model for other tools it suffers from the lack of a web presence, and remedying this is an immediate objective for its editors. Understanding how this might be done presents some challenges, as the scheme is semantically very rich and complex in the range and nature of the relationships it contains. The automatic management of these is already in place using local software, but exporting this to a common data format needs careful thought and planning. Various encoding schemes, both for traditional classifications, and for digital materials, represent variously: the concepts; their functional roles; and the relationships between them. Integrating these aspects in a coherent and interchangeable manner appears to be achievable, but the most appropriate format is as yet unclear.

    Abstract
    This paper examines the differences in the functional requirements of a faceted classification system when used in a conventional print-based environment (where the emphasis is on the browse function of the classification) as compared to its application to digital collections (where the retrieval function is paramount). The use of the second edition of Bliss's Bibliographic Classification (BC2) as a general classification for the physical organization of undergraduate collections in the University of Cambridge is described. The development of an online tool for indexing of digital resources using the Bliss terminologies is also described, and the advantages of facet analysis for data structuring and system syntax within the prototype tool are discussed. The move from the print-based environment to the digital makes different demands an both the content and the syntax of the classification, and while the conceptual structure remains similar, manipulation of the scheme and the process of content description can be markedly different.

    Abstract
    Basic skills of classification and subject indexing have been little taught in British library schools since automation was introduced into libraries. However, development of the Internet as a major medium of publication has stretched the capability of search engines to cope with retrieval. Consequently, there has been interest in applying existing systems of knowledge organization to electronic resources. Unfortunately, the classification systems have been adopted without a full understanding of modern classification principles. Analytico-synthetic schemes have been used crudely, as in the case of the Universal Decimal Classification (UDC). The fully faceted Bliss Bibliographical Classification, 2nd edition (BC2) with its potential as a tool for electronic resource retrieval is virtually unknown outside academic libraries
