These concepts may be combined in various ways to form a synthesized concept for a whole document. This is called Analytico-Synthetic Scheme. In this icheme the groups of documents may be arranged ‘nto classes. Thus a complete scheme may be con- ulrnucled on this basis.
Knowledge is divided into a numbey of bran- «hes according to accepted ideas. In order to devise a system of classification, one has to survey ihe whole range of human knowledge in existence, ic., all the branches of knowledge. Moreover, pro- vision should also be made for the unknown.
NOTATION
In a classification scheme, the notation plays an miportant role. ‘The notation is ‘ta system of aymbols, generally letters and fixyures, used separa- fely or in combination, to represent the divisions of au classification scheme’’.
The notation gives fixity and practicability to a classification scheme. Without it a _ classification «nnnot be applied. Moreover, it cannot be kept in order, It represents the divisions of a classification, neheme. It stands for the heading in a scheme @ classification. In short, a notation is an abbreviated. niga constructed logically and can be used in the place of a term in the classification schedules.
The notation uscd in a scheme should be brief, txpuinsive, adjustable and casily understood. It is of (wo kinds, viz., pure notation and mixed notation. if only one kind of symbol is used, the notation is
