  1. Knowledge Organization By C.RANGANATHAN

  2. Basic Concepts and Terminology • Subject: Subject refers to ‘an organized systematized body of ideas, whose extension and intension are likely to fall coherently within the field of interest and comfortably within the intellectual competence and the field of inevitable specialization of a normal person.

  3. Basic subject • “ A basic subject has been defined as, “a subject without any isolate idea as a component”.

  4. Simple Subject • A subject consisting only of a basic subject idea. Example : Chemistry, Mathematic, Physic etc

  5. Compound Subject • A compound subject is “a subject with a basic subject idea and one or more isolate ideas as components” (Prolegomena, P.84). Example : In ‘Chemistry of halogens”, Chemistry is a basic subject Halogens is an isolate idea.

  6. Complex subject • Complex subject is a “subject formed by coupling two or more subjects expounding, or on the basis of, some relation between them”. For example “statistics for economists,” “Influence of politics on science,” “Difference between history and political science.”

  7. Micro subject • A subject of small extension and great intension, usually embodied in an article in a periodical, or in a part of a book (Ranganathan).

  8. Macro subject • A subject of great extension and small intension, usually embodied in a whole book single volume or multi-volume (Ranganathan).

  9. Micro document • A document, such as an article in a periodical or the part of a book, not having an independent physical existence.

  10. Macro document • Usually a book single volumed or multi-volumed.

  11. Class Number • The class number of a book is a translation of the name of its specific subject into the artificial language of ordinal numbers

  12. Book Number • Ordinal number which fixes the position of a document in a library relative to the other documents having the same ultimate class.

  13. Collection Number • The collection number of a book denotes the collection to which it belongs.

  14. Classification • Classification is a process of grouping like entities to gather and separating unlike entities.

  15. Berwick Sayers defines • Library classification as the arrangement of books on the shelves or description of them in the manner which is most useful (helpful) to those who read.

  16. Arthur Malthy revises Sayers definitions • “The systematic arrangement of books and other material on shelves or of catalogues and index entries in the manner which is most useful to those who read or who seek a definite piece of information

  17. Carveth Read Defines • “A mental grouping of facts (or) phenomena according to their resemblances and differences, so as best to serve some purpose”

  18. According to Prof.S.R.Ranganathan • Library classification is the translation of the name of the subject of a book into a preferred artificial language of ordinal numbers, and the individualization of several books dealing with the same specific subject by means of a further set of ordinal numbers which represent some feelings (features) of the books other than their thought content.”

  19. Some Important Ideas • Artificial language • Ordinal number • Specific subject • Individualization of several books dealing with the same specific subject • Some features of the books other than their thought content.

  20. Need for library Classification • Information explosion • Continuous Expansion of knowledge • Complexity of documents • To meet the fourth law • To maximize the use of documents • To fix a helpful place for newly added documents • To make quantitative study • To weed – out documents

  21. Purpose of Library Classification • Helpful Sequence • Correct Replacement • Mechanized Arrangement • Addition of New Documents • Withdrawal of Documents from Stock • Book Display

  22. Other Purposes • Compilation of bibliographies, catalogues, union catalogues and so on; • Classification of information • Classification of reference queries; • classification of suggestions received from the users; • filing of non-book materials such as correspondence, photographs, films and so on;

  23. Cont., • classification of statistics of various kinds, for instance the classification of statistics with regard to the issuance of books would reflect the pattern of demands in various subjects; • arrangement of entries in classified part of the catalogue

  24. Cont., • assist the cataloguer in deriving subject headings by means of chain procedure; • assist the cataloguer to analyze the thought content of books for deriving subject headings, is case a list of subject headings is used

  25. Cont., • assist the user of a catalogue to refer to the location of the document on the self; and • assist the library staff to prepare a list of documents of a branch library or lending centre from the stock of the central library.

  26. SENSES • Sense 1-Division • Sense 2- Assortment • Sense 3-Ordinal Number • Sense 4-Amplified universe, Entities and Pseudo-entities • Sense 5-Classes retained
