Abstract

Revision of the DDC is based on the growth or recasting of knowledge that is revealed in a decade of publishing. Revision takes place at the Library of Congress and is guided by several professional committees and the advice of experts. 'Decimal Classification Additions, Notes and Decisions (DC&)' conveys revisions of a minor nature between editions. Separate publications, such as for 004-006 Data Processing and Computer Science, make extensive revisions available between editions

Abstract

Arguing that an established technical terminology is crucial to the development of a discipline, and that classification terminology is neither well settled nor widely used by its exponents, this paper provides an explanation of some of the concepts generally accepted by classification theorists. In particular, the elaborate terminology generated by S.R. Ranganathan is examined. Definitions are provided for numerous concepts, including "classification"; "characteristics" and "attributes"; the genus-species relationship; the types of classes (canonical, systems, special, and environmental main classes); the kinds of subject (basic, compound, complex); as well as concepts such as facets, isolates, arrays, and chains. Comparisons between different classification systems, specifically the Dewey Decimal Classification, Colon Classification, and Library of Congress Classification, are also made

Abstract

Acknowledging the importance of classification not only for library and information science but also for the study and mapping of the world phenomena, in this paper we revisit and systematize the main types of classifications and focus on the species of classification mainly drawing on the work of S. R. Ranganathan. We trace the evolution of library classification systems by their structures and modes of design of various shades of classification systems and make a comparative study of enumerative and faceted species of library classifications. The value of this paper is to have a picture of the whole spectrum of existing classifications, which may serve for the study of future developments and constructions of new systems. This paper updates previous works by Comaromi and Ranganathan and is also theoretically inspired by them.

Rez. in: KO 36(2009) nos.2/3, S.180-181 (N.K. Swain): " ... The User's Guide will undoubtedly be of great help to practitioners and tutors, as each chapter includes a summary and exercises. The purpose suggested by the title is fulfilled, serving as a companion to the 19th edition of the Sears List. It is designed a a manual for beginners who will realize the importance of vocabulary control and subject analysis, and start to comprehend the structure and organization of the Sears List as well as the methods and techniques to locate, specify, and construct subject headings. The book, however, lacks a good number of examples for practice. The emphasis seems to have been put more on the theoretical than the practical aspects. Despite this criticism, I unreservedly value the authors' efforts. At the same time, I can't help but wonder if the book will have wide access as the place of publication, the cost and the availability will especially affect the users in developing countries. The User's Guide will be a valuable tool to technical services librarians, subject catalogers, students and teachers of library and information science. It is intended for college and university libraries in general, but more particularly for library schools. The authors produced a work of high quality that stands out in its category.

Abstract

S. R. Ranganathan (1892-1972) has been called the father of the Indian Library movement. He developed the revolutionary Colon Classification (CC), which was published in seven editions from 1928 to 1987. The evolution of the classification through the editions is discussed. The unique features of the CC are described, including the idea, verbal, and notational planes. Tools for designing and evaluating a system are enshrined in his 55 canons, 22 principles, 13 postulates, and 10 devices. Semantic and syntactic relations are enshrined in his PMEST facet formula, fitted with rounds and levels of facets, and other principles, such as the famous wall-picture principle, for citation order of facets. Briefly explained are facet analysis and number building with its notational base of 74 digits. The entry concludes with a discussion of the extent of use of the CC, its enduring contribution to the science of classification, and its future.

Abstract

The origin of the abridged edition of the Dewey system goes back to 1894 when an outline of 192 pages based on the full 5th Edition (1894) was issued for small public and school libraries of North America. New editions have appeared regularly following closely the publication of new full editions. An abridged version, which is always in one volume, comprises an introduction, schedules, four tables (namely 1, 2, 3 and 4) only, and the relative index and other minor features of the full edition, and has shorter numbers. Abridged 15 is a logical abridgement of the DDC23 (2011) and is a product of a new approach to development of an abridged edition of the DDC. Its content has been derived from the DDC database applying a set of rules to extract the edition using the new (2010) version of the editorial support system. The revision process has been informed by interaction with an always widening and diversified Dewey community at home and abroad. It aims to improve the currency of the schedules continuing to serve as shelving tool while recognizing its 'other' uses as a spinoff of its simplicity and inexpensiveness.

Abstract

Ranganathan's Colon Classification (CC) treats knowledge as a multidimensional structure, enshrining a multiplicity of complex relations. This complexity is manipulated within the CC an the basis of numerous of Ranganathan's contributions to subject analysis, including the modes of formation of subjects; an objective rationale for the arrangement of main classes; the PMEST facet formula, extended by the postulate of rounds and levels; a general dependency principle for collocation of related components in a facet formula, phase relationships between the components of complex interdiscipfnary subjects; the recurrence of an APUPA arrangement throughout the linear ordering of materials; and an absolute syntax of ideas.

Abstract

Sears List of Subject Headings (Miller and McCarthy 2010), first published in 1923, is now in its 20th edition. Like most subject headings lists, apart from being a list of preferred (and non-preferred) headings, it also provides patterns, clear instructions, and examples for coining new subject headings not explicitly listed. Key headings form a vital part of the system of coining new headings. It is proposed that more key headings should be designated. Some candidate headings are described. One far-reaching provision seems to be the use of a subdivision of a preferred heading with all of its NTs. Thus, every preferred heading is a potential key heading for all of its NTs. This proposal works on the principle that what is true of a class is true of its narrower classes of all types. Applying this principle will enormously enhance the capacity of the List without adding even an iota to its text and size.

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

Introduction to the methods of classifying and arranging library collections according to the DDC. It begins with a brief history of the DDC, followed by discussions, the methods of analyzing the subject content of documents to be classed, and the proper procedures of assigning class number. Its essential aims is to explain the proper methods of applying the DDC schedules, of locating and assigning the appropriate class number, and of synthesizing a class number if need be. Examples and exercises are based on ed. 20

Abstract

We define knowledge as a system in a perpetually dynamic continuum. Knowledge grows as it is always fragmentary, though quantifying this growth is nearly impossible. Growth, inherent in the nature of knowledge, is natural, planned, and induced. S.R. Ranganathan elucidated the various modes of growth of subjects, viz. fission, lamination, loose assemblage, fusion, distillation, partial comprehensions, and subject bundles. The present study adds a few more modes of developments of subjects. We describe and fit these modes of growth in the framework of growth by specialization, interdisciplinary and multidisciplinary growths. We also examine emergence of online domains such as web directories and focus on possible modes of formation of such domains. The paper concludes that new modes may emerge in the future in consonance with the new research trends and ever-changing social needs.
