Dr. Shalini R. Lihitkar discusses 12 modes of formation of subjects in library classification. These modes include lamination, loose assemblage, fission, dissection, denudation, fusion, distillation, partial comprehension, and subject bundle. Lamination involves combining facts with facets or sub-facets to create compound subjects. Loose assemblage studies the relationship between subjects. Fission splits subjects into subdivisions. Dissection and denudation refer to specific types of fission. Fusion combines main subjects. Distillation develops new disciplines from experiences in other subjects. Partial comprehension and subject bundles group related subjects.

2. Introduction
 Whenever a new specific subject is created , it should be given a helpful
place among the already existing specific subjects without disturbing the
helpful sequence already arrive at.
 Classificationist and the classifier.
 Dr. S.R. Ranganathan for the first time in 1944
 Previously 1. Denudation, 2. Lamination,3. Loose Assemblage
 Two modes added ie is called “Five preliminary modes of formation
 Dissection ,Lamination, Denudation, Loose Assemblage , Super-
Imposition
 Then few modes of formation. Dr. Ranganathan enumerate 12 modes.

4. Lamination1
In this mode, one or more isolate facts are laminated over
basic facet.
This results in compound subject,
e.g. Library Science in India

5. Lamination 2
In this mode, two or more sub- facets of compound facet
are laminated over one another.
e.g. Child(Medicine ) in Ayurveda

6. Loose Assemblage 1
In this mode, two or more subjects – be it simple or
compound- are studied in their mutual relation.
e.g. The text book of physics and chemistry

7. Loose Assemblage 2
In this mode, two or more isolates taken from one and the
same schedule are brought into mutual relation.
e.g. Comparative study of Jainism and Budddhism

8. Loose Assemblage 3
In this mode, two or more isolates taken from one and the
same array of order higher than 1 in one and the same
schedule are brought into mutual relation.
e.g. Relation between UDC & DDC

9. Fission
In this mode, an isolate or a basic subject –be it main or
non-main gets fissioned or split into subdivisions.
e.g.
Biology
Botany
(Plant
Science)
Zoology
(Animal
Science)

10. Dissection
This is term used to denote fission when we consider an
array of divisions of an isolate or of a basic subject resulting
from fission
e.g. Botany- Agriculture- Zoology
All are split of biology but we consider them as isolate
subject

11. Denudation
This is term used to denote fission when we consider one
and only one of sub- divisions of an isolate or of a basic
subject resulting from fission
e.g. Philosophy Logic Deductive Logic
Philosophy
Logic
Deductive
Logic

12. Fusion
In this mode two or more main subjects are fused in such a
way that each of them loses its individuality in respect of the
schedules of isolates needed to form the compound subject
going with it.
e.g. Biology+ Chemistry= Biochemistry

13. Distillation
In this mode, a pure discipline is evolved as a main subject,
out of the experiences in the appearance-in-action in
diverse compound subjects going with different most basic
subjects going with different most basic subjects or
occasionally even with host compound subjects.
e.g. Management.

14. Agglomeration (=Partial Comprehension)
Several main subjects are sometimes treated integrally or
disjunctively in one and the same book.
e.g.
• Natural Sciences
• Humanities
• Social Science

15. Cluster (=Subject Bundle)
In this mode new kind of partial comprehension of subjects
is formed.
e.g.
• Ocean Sciences
• Space Sciences
• Defence Sciences
