    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 paper analyses the importance of data presentation and modelling and its role in improving the management, use and exchange of analytico-synthetic classifications in automated systems. Inefficiencies, in this respect, hinder the automation of classification systems that offer the possibility of building compound index/search terms. The lack of machine readable data expressing the semantics and structure of a classification vocabulary has negative effects on information management and retrieval, thus restricting the potential of both automated systems and classifications themselves. The authors analysed the data representation structure of three general analytico-synthetic classification systems (BC2-Bliss Bibliographic Classification; BSO-Broad System of Ordering; UDC-Universal Decimal Classification) and put forward some core requirements for classification data representation

    Abstract
    The main object of the paper is to demonstrate in detail the role of classification in information retrieval (IR) and the design of classificatory structures by the application of logical division to all forms of the content of records, subject and imaginative. The natural product of such division is a faceted classification. The latter is seen not as a particular kind of library classification but the only viable form enabling the locating and relating of information to be optimally predictable. A detailed exposition of the practical steps in facet analysis is given, drawing on the experience of the new Bliss Classification (BC2). The continued existence of the library as a highly organized information store is assumed. But, it is argued, it must acknowledge the relevance of the revolution in library classification that has taken place. It considers also how alphabetically arranged subject indexes may utilize controlled use of categorical (generically inclusive) and syntactic relations to produce similarly predictable locating and relating systems for IR.
