Abstract

Summary of the decisions taken for the revision of the Bliss Classification and their consequences concerning internal organisation of classes, facet analysis, citation order, filing order, notation, and the A/Z index. Also, maintenance of the new BC and its possible future envisaged for about a century. It will be published in 20 separate volumens in the forthcoming 3-4 years

Abstract

Henry Evelyn Bliss was probably the greatest American contributor to the theory of the classification of library materials. The first edition of the classification scheme he developed is discussed here by a major British thinker in this area, Jack Mills. After some years of use, the scheme was extensively revised, under the Editorship of the same Jack Mills, and the resulting second edition of the Bliss Bibliographic Classification is discussed in the entry by that name.

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.
