2. •INTRODUCTION:
Classification is artificial arrangement of document or likewise . We
classify the things whether in home, shops or the library. In library
classification we deals with documents. As a classificationist, should kept
in mind that the coordinate classes in an array should be arranged in an
helpful manner for better use of the user’s.Ranganathan analyzed the
problem and put a chapter in element of classification (1944) on helpful
sequence.
the basic canon of classification is the “canon of helpful sequence.
Various principle are used to determine the helpful sequence in which any
specific subject should be arranged.
•Concept Of Helpful Sequence:
The main purpose of classification is helpful sequence:
•Like things are put together, while unlike things are put aside.
•The need of classification of knowledge is to maintain a helpful sequence
between the various division of knowledge.
•Structure of knowledge is so complicated that is very difficult to maintain
helpful sequence.
•In other words helpful sequence may help as per need and purpose for the
users of the scheme of classification.
4. Usage Of Helpful Sequence In CC:-
Principle of latter in time:
If the subjects in an array of subjects or the isolates in an array of isolates
have originated in different times they should be arranged in a parallel
progressive time sequence, except any other overwhelming rules it out.
Example illustrated in seminar
Principle of earlier in time:
If the subjects in an array of subjects or the isolates in an array of isolates
have originated in different times they should be arranged in a parallel
progressive time sequence, except any other overwhelming rules it out.
this is the reverse principle of “principle of latter in time
Principle of latter in evolution:
If the subjects in an array of subjects or the isolates in an array of isolates
belong to different stages of evolution they should be arranged parallel
to the evolutionary sequence.
Example illustrated in seminar
5. Principle of earlier in evolution:
If the subjects in an array of subjects or the isolates in an array of isolates
belong to different stages of evolution they should be arranged parallel
to the evolutionary sequence. This is also the reverse principle of
“principle of latter in evolution”.
Principle of spatial contiguity:
If the subjects in an array of subjects or the isolates in an array of isolates
occur contiguously in space-roughly along unidirectional liner be
arranged in a spatial sequence expect any of the following is already
applied: d)
a)
c)
b)
a) Entities along vertical line.
b) Entities along horizontal line.
c) Entities along circular line.
d) Entities along radial line.
6. a) Entities along Vertical line:
i. Principle of bottom upwards:
If the subjects in an array of subjects or the isolates in an array of isolates
can be conveniently taken to occur along a vertical line, they may be
arranged from bottom upwards, if it is helpful.
Example illustrated in seminar
II. Principle of top downwards:
If the subjects in an array of subjects or the isolates in an array of isolates
can be conveniently taken to occur along a vertical line, they may be
arranged from Top to downwards, if it is helpful.
Example illustrated in seminar
b) Entities along horizontal line:
i. Principle of left to right:
If the subjects in an array of subjects or the isolates in an array of isolates
can be conveniently taken to occur along a horizontal line, they may be
arranged from left to right, if it is helpful.
ii. Principle of right to left:
If the subjects in an array of subjects or the isolates in an array of isolates
can be conveniently taken to occur along a horizontal line, they may be
arranged from left to right, if it is helpful.
7. c) Entities along Circular line:
i. Principle of clockwise direction:
If the subjects in an array of subjects or the isolates in an array of isolates can be
conveniently taken to occur along a circular line, they may be arranged in the
clockwise direction, if it is helpful.
Example illustrated in seminar
II. Principle of anticlockwise direction:
If the subjects in an array of subjects or the isolates in an array of isolates can be
conveniently taken to occur along a circular line, they may be arranged in the
anticlockwise direction, if it is helpful.
Example illustrated in seminar
d)Entities along Radial line:
i. Principle of periphery to center:
If the subjects in an array of subjects or the isolates in an array of isolates can be
conveniently taken to occur along a radial line of a circle, they may be
arranged from periphery to center, If it is helpful.
ii. Principle of center to periphery:
If the subjects in an array of subjects or the isolates in an array of isolates can be
conveniently taken to occur along a radial line of a circle, they may be
arranged from periphery to center, If it is helpful.
Example illustrated in seminar
8. • Principle of increasing quantity:
If the subjects in an array of subjects or the isolates in an array of isolates admit a
quantative distinction, they may be arranged according to their increasing
quantity.
Example illustrated in seminar
• Principle of decreasing quantity:
If the subjects in an array of subjects or the isolates in an array of isolates admit a
quantative distinction, they may be arranged according to their decreasing
quantity. It is also reverse principle of “principle of increasing quantity”
Example illustrated in seminar
• Principle of increasing complexity:
If the subjects in an array of subjects or the isolates in an array of isolates show
different degree of complexity, they may be arranged parallel to the increasing
complexity.
Example illustrated in seminar
• Principle of decreasing complexity:
If the subjects in an array of subjects or the isolates in an array of isolates show
different degree of complexity, they may be arranged parallel to the decreasing
complexity.
9. • Principle of canonical sequence:
If the subjects in an array of subjects or the isolates in an array of isolates are
traditionally referred to in a specific sequence, although no underlying
principle is discoverable it will be convenient to conform to this traditional
sequence.
Example illustrated in seminar
• Principle of literary warrant:
If the subjects in an array of subjects or the isolates in an array of isolates may
be arranged in the sequence of the decreasing quantity of the document
published or anticipated to be published on them, except any other
overwhelming rules it out.
Example illustrated in seminar
• Principle of alphabetical sequence:
When no other sequence of the subjects in an array of subjects or the isolates
in an array of isolates is more helpful, they may be arranged alphabetical by
their names current in international use.
Example illustrated in seminar
10. Findings:
• The helpful sequence plays an important role in designing a scheme of
classification.
• In CC most of the classes Ranganathan use the “Principle of canonical
sequence”.
• In dividing the space isolates Ranganathan use the “principle of clockwise
direction".
• In each class for dividing the coordinate classed in an helpful manner
Ranganathan use the various principle of helpful sequence, like in class
“Medicine” Ranganathan use both the principle of “bottom to upwards”
and “Principle of top downwards”.
Conclusion:
•It may be noted that between those principle most of the principle are
in pair. In fact, anyone of the two principle in pair may be applied to
secure a helpful sequence. The preference to a particular principle in
pair may be given if it is found to give a more helpful result. To arrange
the coordinate classes in an array an appropriate principle for the sets of
the principle of helpful sequence can be found to give them a
consistence sequence. However the choice of principle depends largely
on the judgment of the classificationist.
