Abstract

The ways in which notation can be used to express the content of documents to which it relates are various. At the most superficial level notation can correspond to the hierarchical structure of the schedules or link to literal components. The notation of compound concepts can express the structure and composition of the compound, and systems exist in which symbols denote the functional roles of the constituent elements and the relationships between them. At the highest level notation can be used to mirror the actual structure of those entities which it represents, as in the case of mathematical systems or chemical compounds. Methods of displaying these structures are examined, and the practicality in a documentary context is questioned, with particular reference to recent revision work on the chemistry class of the Bliss Bibliographic Classification 2nd edition (BC2)

Abstract

Notations are systems of symbols that can be combined according to syntactical rules to represent meanings in a specialized domain. In knowledge organization, they are systems of numerals, letters and punctuation marks associated to a concept that mechanically produce helpful sequences of them for arranging books on shelves, browsing subjects in directories and displaying items in catalogues. Most bibliographic classification systems, like Dewey Decimal Classification, use a positional notation allowing for expression of increasingly specific subjects by additional digits. However, some notations like that of Bliss Bibliographic Classification are purely ordinal and do not reflect the hierarchical degree of a subject. Notations can also be expressive of the syntactical structure of compound subjects (common auxiliaries, facets etc.) in various ways. In the digital media, notation can be recorded and managed in databases and exploited to provide appropriate search and display functionalities.

Abstract

The history of book numbers starts only with Melvil Dewey, as before hom books were shelved in fixed location systems. The article traces the early attempts by Dewey himself to combine class numbers with author numbers and shows the development in the individualization of book numbers by a great number of classificationists and classifiers, among which J. Schwartz, W.S. Biscoe, Ch.A. Cutter, K.E. Sanborn, J.D. Brown, A.F. Rider and finally S.R. Ranganathan whose faceted structure and ease of application of book numbers seems still to be the optimal solution. Two rival systems of book numbers are alphabetical by author and chronological by the year of publication of a books. The concluding chapter is devoted to the existing literatur on book numbers and laments its vanishing quality. The study of book numbers is not getting due attention.

Abstract

This article presents a new idea on shelving printed books and finding books in libraries. The author advocates that traditional book classification number (TBCN) systems should be replaced by a better indexing method for books in libraries. The author proposes a new way of seeking books for library users wishing to locate them called a 'dynamic book subject number' (DBSN) system. The new system combines new indexing rules and automated system technology to create settings in which a book's 'subject number' can change rather than having a particular permanent classification number assigned to it. The new way encourages library users to seek books through a user-friendly cataloging system by choosing subjects from the embedded database. The database contains thousands of subjects with their corresponding Arabic codes. For printed books, the DBSN ushers in a new era in the relationship between library users and the books.
