Colon classification

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.
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.
As an example, the subject "research in the cure of tuberculosis of lungs by x-ray conducted in India in 1950" results in a call number
- L,45;421:6;253:f.44'N5
The components of this call number represent
- Medicine,Lungs;Tuberculosis:Treatment;X-ray:Research.India'1950
