Abstract: Examines the implications of the overwhelming proliferations in the universe of knowledge. Evaluates the versatility of a notation capable of implementing the concepts of phase, facet, round, level, and zone of array. Summaries the past work of FID/CA. States the notational problems arising out of the concept of zone in an array. Improves the application of subject device in an analytico synthetic scheme of classification. Extends the idea of disjunctive incidence to all facets. Psychological and physiological limit to the number' of digits in an isolate number is shown to coincide with number of relevant characteristics usually needed in a train of characteristics belonging to a facet. The capacity of the notational system of the current form of analytico-synthetic scheme of classification is estimated to be of the order of 1021 at documentation level. It is of the order of 108 at the level of book-classification. The concept of Abstract Classification i s developed on the analogy of pure mathematics. The need for pursuing this discipline is shown to be a consequence of the depth classification needed for efficient documentation work. The problems needing immediate attention in depth classification are indicated.
