CANON OF PERMANENCE
The word 'canon' means a body of principles, rules or standards. And 'Permanence' means intended to last for a long time or forever. Here, canons are useful for designing a scheme of classification. Ranganathan explains the canon of permanence as that the facets used in a classification system should continued to be used as long as there is no change in the purpose of the system.
And the canon states that, "A characteristic used as the basis for the classificatoin of a universe should continue to be unchanged so long as there is no change in the purpose of classification."
Ranganathan also states some examples:
1. Imagine the result of using colour as a charecteristic for classifying chameleons. This suggests that permanence equates not to use the same facets, but to use facets that reflect permanent qualities of the entities in question. A similar example would be to classify the politicians as to their political complexion, which keeps on changinig.
2. In some schemes for classification, periodicals are divided into two classes:
(a) Those published by learned societies, and
(b) Those not published by learned societies.
This has lead to a little difficulty in libraries; that in Classified Catalogue code, periodicals undergo frequent changes in the authority or agency publishing them.
3. The periodical Medical Library, which had been running its course from 1883 without a learned "Godfather" was taken in 1890 as its official organ by the American Electro-therapeutic Association which was just then founded. In 1926, it took as a joint foster father the International Association of Climatologists.
3. The Journal of Indian Botany was launched as a private concern in Madras in September 1919. It was the property of a private individual, Mr TRD Bell, then chief conservator of forests, Bombay. In 1920, the Indian Botanical Society came into existence, and at a meeting held on 3rd Febraury 1922, it decided to takeover the Journal as the property and official organ of that learned body.
4. The dalmatian dog will always be a dalmatian, thus the facet "Breed" represents a permanent charecteristic of dogs, although it could be argued that the types of available types of dog breeds can change. It is perhaps this latter quality that is more important in this canon.
