Knowledge Organization: Classification and Cataloguing Theory

Notes For Facet Formula (Principle of Inversion): In an analytico-synthetic classification, the
implementation of the Principle of Increasing Concreteness requires that the facets in the
facet formula of a basic class should be in the decreasing sequence of concreteness. If the
scheme has rounds of facets, the facets in each round should be in the decreasing sequence
of concreteness.
For Helpfulness in Array
Principle of Increasing Quantity: If the characteristic used admits of quantitative
measurement, the sequence of the classes may be in the ascending sequence of the measure
in which the classes share the characteristic.

Principle of Later-in-Time: If the classes in an array have originated in different times,
they may be arranged in a parallel progressive time-sequence.
Principle of Later-in-Evolution: If the characteristic is of an evolutionary nature, the
sequence of the classes may be parallel to the course of evolution.
Principle of Spatial Continuity: If the classes of an array occur contiguously in space, they
may be arranged in a parallel spatial sequence.

Principle of Increasing Complexity: If the classes in an array show different degrees of
complexity, they are arranged in the sequence of increasing complexity.

Principle of Canonical Sequence: If the classes are traditionally referred to in a specific
sequence, although no underlying principle is discoverable, it will be convenient to confirm
to this traditional sequence.

Principle of Favoured Category: The classes in an array may be arranged in the sequence
of the decreasing quantity of documents published on them.

Principle of Alphabetical Sequence: When no other sequence of the classes in an array is
helpful, they are arranged alphabetically by their names current in international usage.

Self Assessment

State whether the following statements are true or false:
9. The notational system of a scheme of book classification should provide for variations in
Canon of Book Number.
10. When no other sequence of the classes in an array is helpful, they are arranged alphabetically
by their names current in international usage.

7.6 Recent Developments in Classification

Change is the dominant factor of human life. There is immense importance to change in present
period and it is the cause of human progress. The Library and Information Science is no exception
to this. Therefore, it is necessary to include new trends in the syllabi. As a result of this change
new concepts are coming forward. To prepare a skilled librarian the library organisation and
the syllabus in it is very important. Nowadays library is not only confined to the transaction of
books but it has become a centre of information. Therefore, it is very necessary to apply the new
trends in the syllabi. The recent developments in library classification can be preferably
considered in the following ways:

1. Knowledge of Computer: Today’s age is termed as ‘computer age’. One who has no
knowledge of ‘computer’ is regarded as illiterate. That is why the syllabus of computer is
included in Library and Information Science.
