After reading this Unit, you will be able to • know the origin and working of Colon Classification; • grasp the underlying principles: of the scheme; and • classify documents according to CC. 13.1 INTRODUCTION You have now studied in detail the Dewey Decimal Classification and Universal Decimal Classification schemes. This Unit attempts to familiarise you with the underlying principles of Colon Classification. CC differs in several respects from the other two schemes, which you have already studied in this Block. S.R. Ranganathan, the author of CC, was well aware that a scheme of classification should be able to meet the challenge of ever rowing universe of knowledge and it 55 should 'be able to Study of Selected Schemes of , Classification accommodate, at an appropriate place, any new subject without disturbing the arrays already formed. The seventh edition of CC has succeeded to a large extent in fulfilling this objective; Two basic strategies for number building in CC are i) subject analysis, and ii) synthesis. The analysis of a given subject results in the facetisation of the subject, as treated in the document, on the basis of five fundamental categories and their manifestation in it. Synthesis consists of bringing together the facets manifest in a subject to represent, as completely as possible, the description of that subject. Synthesis also has another connotation. It consists of connecting to the core subject those other aspects, which it shares with other subjects. By dint of its capabilities of analysis and synthesis, CC is known as an analytico-synthetic scheme. It is also described as a Freely Faceted Scheme. Under a rigidly faceted scheme, each main class was given a facet formula and the numbers were coined with the help of a connecting digit, colon. The drawback under a rigidly faceted scheme, with a single connecting symbol, resulted from the cluttering of the connecting symbol, i.e., whether a facet was present or absent, it had to be represented by a colon. With the introduction of 'separate connecting digits for personality, matter and energy facets in the fourth edition of CC, it became possible to represent only those facets in the number that are manifested in the subject treated in the document. Because of this facility, CC has since been called Freely Faceted. 13.2 GENESIS OF COLON CLASSIFICATION Ranganathan was a mathematics lecturer. It was a mere accident that he was appointed Librarian of the Madras University Library in the year 1924. He was soon deputed to Britain for an observational tour of British libraries. While in Britain he also attended classes in the School of Librarianship, University of London. Berwick Sayers, known as' the grammarian of library classification, was one of the teachers at the School. During his tour of Britain; Ranganathan visited several libraries and was quick to notice the lacunae in the classification schemes in use then. A chance visit to a departmental store in London gave Ranganathan a clue for evolving a scheme of classification. He saw the demonstration of a toy called meccano set. The meccano set consists of several slotted strips, rods, wheels, screws, nuts and bolts with which several different models could be made. This gave him the idea that in a classification scheme there should be standard units that could be joined by connecting symbols. Ranganathan's standard units resembled the strips and his connecting symbols resembled the nuts and bolts of the meccano set. The standard units became the schedules. Thus, a class number could be constructed with the different elements enumerated in the schedules with a connecting symbol and he chose the colon as the connecting symbol. This was, dip, Ranganathan's conception of Colon Classification. The foundation of Colon Classification was laid in Britain in the year 1924. In 1925, his journey back to India gave Ranganathan ample time to work on the schedules. The library on the ship he was travelling in and the Madras University Library's book catalogue, which he was carrying with him served as the working equipment for him. 13.2.1 First Edition On reaching Madras he took up the work of classifying the Madras University Library collection. The years between 1925 and 1932 were devoted mainly to the\ construction' of the schedules of CC. In 1929, he also established a library school at the University. Both teaching and library work at the University contributed immensely to the publication 'n 1933 of the first edition of Colon Classification. It had three distinct par: 127 pages of rules explaining the underlying principles, 135 pages of schedules and 106 pages Of index. The notation was mixed, consisting of the-26 Roman capital letters denoting main classes, Indo-Arabic numerals- and also Roman lower case letters. The colon (:) was used as the connecting symbol for joining facets. Each main class was provided with a facet formula. 13.2.2 Search for Theory Ranganathan was aware of several inconsistencies in his scheme and did not fight shy of consulting subjects experts to know the gamut of each discipline. At the same time he tried to 56 evolve a theory of library classification. The years from 1933 to 1939 were spent in working Colon Classification (CC) on the theory of classification. It was during these years that several Canons of Classification were formulated. The result was the publication of Prolegomena to Library Classification in 1937. Based on this theory, the second edition of Colon Classification was published in 1939. The changes from the first to the second edition were not substantial.. In this edition, two new ,concepts of Octave principles and auto-bias device were introduced. A new main class 8 Spiritual Experience and Mysticism carne into being. The first edition, as already said, had three parts. A fourth part was added in the second edition. This additional part contained about 3,000 examples, which were illustrative of the rules given in the first part.

He spent two years at Banaras Hindu University from 1945 to 1947. He was, however, bogged down -in administrative work and all research came to a standstill. It was Sir Maurice Gwyer, the then vice-chancellor of Delhi University, who invited, Ranganathan to Delhi and gave him all facilities to devote himself to serious research.The eight years from 1947 to 1955 that, he stayed at Delhi University were productive. Team research became possible, and a quarterly journal, Abgila, became the instrument to publish the research findings. After a lapse of eleven years the third edition of Colon Classification 'appeared in 1950 without any major modifications. There were, however, a few changes in terminology. The findings of research at Delhi culminated in a dynamic theory of library classification.A major finding was that in any subject there could be only five ingredients. This gave rise to the Postulate of Five Fundamental Categories, which were stated as Personality, Matter, Energy, Space and Time (PMEST). The postulate further stated that these five -fundamental categories; fall in the sequence of P M E S T. Each fundamental category was assigned an indicator digit i (connecting symbol) as shown below: Fundamental Category Indicator Digit ' Personality ,(comma) Matter ;(semi-colon) Energy :(colon) Space .(dot) Time .(dot) 57 Study of Selected Schemes of Classification The indicator digit for time was later changed to a single inverted comma ('). The ordinal value of the connecting symbols was also determined. These findings were included in the fourth edition of Colon Classification (1952) and the second edition of Prolegomena to Library Classification, published in 1957. The fifth edition appeared in the year 1957. The fifth edition had made several changes both in the rules and also in the schedules. Many Greek letters were introduced in the fourth edition to expand the base of the main classes. These were found to be irritants and were replaced in the sixth edition by empty and emptying digits (we will discuss the emptying digits later in, this Unit). Some changes were also effected in a few main classes. In addition, the second level of space and time facets was introduced. Meanwhile, the sixth edition of Colon Classification, was published in .1960. At about this time, Ranganathan had shifted to Bangalore. A new centre, Documentation Research and Training Centre (DRTC), was established-by the Indian Statistical Institute with Ranganathan as its honorary professor.

  • Strategies for Collecting Electronic Resources on the Qur’Anic Researches
    International Journal on Quranic Research (IJQR) © 2013 Centre of Quranic Research Vol.3, No. 4, June 2013, Pp. 57-78 (CQR), University of Malaya, Malaysia STRATEGIES FOR COLLECTING ELECTRONIC RESOURCES ON THE QUR’ANIC RESEARCHES Amar Arbaoui, Yasser M. Alginahi & Mohamed Menacer ABSTRACT Electronic dissemination of digital information has benefited from recent advancements in Information and Communication Technologies (ICTs) and dissemination of Islamic digital content in different formats has taken advantage of this rapid progress in technology. Information is available in many formats and on many different applications and devices. However, the online availability of such resources on Qur’an and its sciences is very limited. In this work, digital Qur’an resources available from authentic sources will be used to formulate strategies on how to extract, format, present and make these resources available for researchers in a centralized knowledgebase. The methodology starts with collecting these authentic electronic Islamic resources. Next, resources are classified into their main categories, sub-categories and related categories. Then, the list of metadata for each type of resource is developed. Following this, strategies for efficient dissemination for the different types of digital resources are developed; depending on the format of the files, the metadata is extracted automatically, if possible, otherwise data is entered manually into the knowledgebase. Therefore, the manual entry of data into the knowledgebase for resources having poor or lacking metadata would efficiently help researchers to easily locate the resources they are searching for. Developing these strategies for each type of format could efficiently help in the search process. From the data collected so far, the amount of data gathered shows that books contribute to the highest number of resources available in this area followed by post graduate dissertations, conference papers and journal papers respectively.

The major milestones in philosophical and bibliographic classifications are presented to show that the classification system has evolved from purely philosophical schemes, which were focused on the systematization of knowledge, into modern bibliographic classification systems. Facet analysis is considered a contribution to the classification process since it allows the use of an approach that encompasses different points of view of the same subject, as opposed to the enumerative systems. This article also discusses Ranganathan’s five fundamental categories, known as Personality, Matter, Energy, Space and Time, and points out to criticism of this form of categorization in the literature.

It predominantly acts as the backbone of the library services provided in a library. In this study an attempt has been made to make an extensive study on how literature schedule is treated i.e. how class number building approach is carried out with the help of certain selected titles. An attempt has been made to delineate and outline how the literature schedule is practiced in different ways in both the classification scheme. By assigning class numbers according to both the schemes to the titles belonging to literature schedule it has been tried to outline the nature of treating the literature schedule.

Concluding Remarks ABSTRACT There have been several milestones in the history of library classification but most of the schemes failed to meet the new challenges in the organisation of information. Dr. S. R. Ranganathan tried to revolutionise the whole thinking on classificatory approach, when he devised the Colon Classification (CC) in 1933. He developed the Colon Classification scheme with a sound theoretical background based on normative principles, Five laws of Library science, canons, etc. One important feature of CC is that, its use is not confined to information storage and retrieval alone. This paper presents an over view of different editions of the CC highlighting the salient features of the editions. Further the implication of Five Laws of Library Science has been described. The authors stressed that the features of such as greater hospitality, specificity and mixed notation has paved the way to design and develop the depth schedules on various micro level subjects and so far about 130 micro schedules have been published. The impressions by the leading LIS professionals during and after Ranganathan’s time have been highlighted.

  • Classification Model for Libraries in the Digital Environment
    487 Classification Model for Libraries in the Digital Environment K S Chudamani Abstract There is lot of research carried out about the models of classification suitable for libraries in digital environment. UDC, CC, DDC, LCC are used in libraries all over the world. People are using existing Classification models and automating them for use in the digital environment. Though this is a right step, one has to look at the operational requirements of the digital environment. Keeping this fact in view, this paper analyses the requirements of the digital environment and points out the adaptations required for the traditional schemes to suit the digital environment . Keywords : Classification, Classification Models 0. Introduction Various classification models are used in the organization of knowledge in libraries. The well-known among them are 1. Dewey Decimal Classification (DDC) 2. Universal Decimal Classification(UDC) 3. Colon Classification (CC) Each of these has certain common characteristics and distinct characteristics. They were adopted by different libraries for serving a variety of purposes like classifying books, articles and technical reports, for providing shelf access, etc. This paper explores the modifications required to these models to augment information retrieval in the digital environment 1. Classification Models DDC is enumerative and can be easily memorized. The notation is usually brief. Though it has few analytico - synthetic features, they are very limited and as such produces brief notation. This helps user to memorize the number easily. Also, its updated editions are produced regularly and hence it is possible to update the organization of documents without much effort from the classifier. Though its notation is mixed, most part of it is purely numerical.

R. Ranganathan (1892-1972), veritably called the father of Indian library movement. It outlines brief history of the seven editions of his revolutionary colon classification (CC) from 1928 to 1987. Seven editions are grouped into three evolutionary versions. It states the unique features of the CC as based on his deep study of the nature and growth of knowledge, and explains the work of designing a classification system into three successive but demarcated planes of work, namely, idea, verbal, and notional planes. Tools for designing and evaluating a system are enshrined in his 55 canons, 22 principles, 13 postulates and 10 devices. Further, this paper discusses the division and mapping of knowledge, types of subjects, and modes of their formation in the universe of knowledge as envisaged by Ranganathan. 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. It also briefly explains facet analysis and number building with its notational base of 74 digits, and concludes with extent of its use and its enduring contribution to the science of classification and its future.

Enumerative Mohinder Partap Satija classifications have become shibboleths of an outdated Guru Nanak nev University, Amritsar, India past.
