Abstract

A medium-length book, based on lectures, aimed at classificationists, not cataloguers or classifiers. Ranganathan begins with his Five Laws and a definition of classification and its purposes. He gives a list of 108 subjects in "unhelpful alphabetical sequence" and shows how they can be grouped into subjects, and then how each each subject's terms can be organized in a helpful and useful way, thereby demonstrating and building up his basic canons, postulates, and principles of classification. All of that, roughly the first half of the book, will be of interest to anyone starting to make classification systems. It has all of what makes Ranganathan's work so delightful to read: his unending concern for the user, his deep thought, and his warmth, humour, and spirituality. The second half of the book, however, has what can make his work difficult: his unyielding belief that the Colon Classification is the only system worth using. The reader will not be very interested in repeatedly classifying books under various systems and then reversing the process to see how closely the call number matches the subject. However, the reader can take the ideas so clearly presented in the first half of the book and then veer off to build his or her own system, while remembering that if his classification laws are likened to Euclid's laws of geometry, there is no room for a Riemann or Lobachevksy in Ranganathan's strict world.

Abstract

Among the theorists in the field of subject analysis in the twentieth century, none has been more influential than S. R. Ranganathan (1892-1972) of India, a mathematician by training who turned to librarianship and made some of the most far-reaching contributions to the theory of librarianship in general and subject analysis in particular. Dissatisfied with both the Dewey Decimal Classification and the Universal Decimal Classification, Ranganathan set out to develop his own system. His Colon Classification was first published in 1933 and went through six editions; the seventh edition was in progress when Ranganathan died in 1972. In the course of developing the Colon Classification, Ranganathan formulated a body of classification theory which was published in numerous writings, of which the best known are Elements of Library Classification (1945; 3rd ed., 1962) and Prolegomena to Library Classification (1967). Among the principles Ranganathan established, the most powerful and influential are those relating to facet analysis. Ranganathan demonstrated that facet analysis (breaking down subjects into their component parts) and synthesis (recombining these parts to fit the documents) provide the most viable approach to representing the contents of documents. Although the idea and use of facets, though not always called by that name, have been present for a long time (for instance, in the Dewey Decimal Classification and Charles A. Cutter's Expansive Classification), Ranganathan was the person who systematized the ideas and established principles for them. For his Colon Classification, Ranganathan identified five fundamental categories: Personality (P), Material (M), Energy (E), Space (S) and Time (T) and the citation order PMEST based an the idea of decreasing concreteness.

Abstract

THE COLON CLASSIFICATION is the latest scheme in the field of classification. It has revolutionised thinking in classification and stimulated research in it. This new method is suited to small and large, general and special libraries and can be used in classifying whole books as well as individual articles in a periodical or sections in a book.. It is being taught in all schools o Library Science all over the world, not only as a means of arranging books on shelves but also as a means of finding out the focus of a book in systematic way and finding the requirements of a reader while doing reference service. The new methodologies in classification invented as part of the Colon Classification-the Facet Analysis, the Phase Analysis and the Zone Analysis--have lifted Practical Classification from guesswork to scientific method. They are forming an important theme in international conferences on information retrieval.
