Difference between faceted and enumerative classifications

[Qalandar Baba]

Dear Forum Members,

Please differentiate faceted classification from enumerative classifications.

Which classification schemes are tailor made schemes?

Kindly explain in easy way with examples

Tthanks in advance.

enumerative classifications enumeration is normally achieved by first identifying the main disciplines to be covered by the scheme, either on a philosophical or pragmatic basis, and allocating each a main class. Then each discipline is divided into subclasses. This process of subdivision is continued until an appropriate level of specificity has been achieved. The object is to provide one place, and one place only, for each subject.
For example, the DDC classifies "Philosophy and Psychology" as class 100, which is further broken down into 100: Philosophy, 110: Metaphysics, 120: Epistemology, etc. Many enumerative schemes are thus also hierarchical.

Enumerative classifications are essentially top-down methods of analysis: you start at the top of the hierarchy and work your way down until you find a suitable heading or term that describes or classifies your text.

faceted classification arose from the need to accommodate complex or multi-concept subjects. Jennifer E. Rowley, in her book Organizing Knowledge, notes that what Ranganathan recognized was that the world of knowledge was growing quickly, with new areas of knowledge being discovered and new ways to combine existing subjects. He understood that any classification that attempted to enumerate a finite number of subjects without full capabilities for expansion to allow for new areas of knowledge could never meet the needs of the future.
