Colon classification (CC) is a system of library classification developed by S. R. Ranganathan. It was the first ever faceted (or analytico-synthetic) classification. It is especially used in libraries in India. A library classification is a system of coding and organizing library materials (books, serials, audiovisual materials, computer files, maps, manuscripts, realia) according to their subject. ... Shiyali Ramamrita Ranganathan (August 9, 1892, Shiyali, Tamil Nadu - September 27, 1972, Bangalore) was an innovative mathematician and librarian from India. ... A faceted classification system allows the assignment of multiple classifications to an object, allowing searching and browsing of related information through several classes. ... Classification may refer to: Taxonomic classification See also class (philosophy) Statistical classification Security classification Hint: Language use may refer to a taxonomic classification that is used for statistical purposes also as a statistical classification (like International Statistical Classification of Diseases and Related Health Problems). ... Modern-style library In the traditional sense of the word, a library is a collection of books and periodicals. ...

Its name "Colon classification" comes from the use of colons to separate facets in class numbers. However, many other classification schemes, some of which are completely unrelated, also use colons and other punctuation in various functions. They should not be confused with Colon classification. A colon is a punctuation mark, with one dot above another, e. ... Punctuation marks are written symbols that do not correspond to either phonemes (sounds) of a spoken language nor to lexemes (words and phrases) of a written language, but which serve to organize or clarify written language. ...

Medicine,Lungs;Tuberculosis:Treatment;X-ray:Research.India'1950

Organization

The Colon Classification uses 42 main classes that are combined with other letters, numbers and marks in a manner reminiscent of the Library of Congress Classification to sort a publication. The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress. ...

Facets

CC uses five primary categories, or facets to further specify the sorting of a publication collectively called 'PMEST'.

 ; matter or property

 : energy

. space

' time
