Use of Normative Principles for Comparison of Schemes of Classification

Ascertains, by an a priori approach, that the essential difference between two schemes of classification lies in their capacity to give co-extensive (CN) and in their having self-perpetuating quality. Discusses and demonstrates the use of Normative Principles for the systematic comparison of two schemes of classification. Confirms that the essential difference between the schemes of classification lies in their capacity to give co-extensive (CN) for the subjects already embodied in documents and also for those that may arise in the future as the universe of knowledge develops. Suggests the examination of an alternative set of postulates with reference to the two essential criteria for the comparison.
