The PPT is about Father of Library Science in India Dr. S. R. Ranganathan.

1. CONTRIBUTION OF DR. S.
R. RANGANATHAN
In Library science field

2. • Five Laws of Library Science
•Colon classification
• Classified Catalogue Code
•Chain Indexing

3. ◦First Law: Books are for use
Implication:
Library Location
Library Hours
Library Furniture
Book Selection
Library staff

4. ◦Second Law: Every Reader his
Book
The second law also emphasizes the need for
Librarians to treat patrons equally. The implication
of the second law is marketing of library and
information services to meet user’s information
needs satisfactorily by collecting and interpreting
information, studying and understanding the
needs of patrons, and matching the needs with
the available resources.
However this law has some obligations i.e. (a)
Obligations of the State (b) Obligation of the
Library Authority (c) Obligation of Library Staff (d)
Obligation of the Reader

5. ◦Third Law : Every readers its
books
Implication:
Open Access
Shelf Arrangement
Easy Access
Catalogue
Publicity
Display of Book

6. ◦Fourth Law : Save the Time of the
Reader
Implication:
Classified arrangement
Catalogue Entry
Open Access
Reference Services
Issue Method
Centralized/ Pre-natal Cataloguing
Stack Room Guides
Library Location

7. ◦Fifth Law : Library is a Growing
Organism
◦ Implication:
Growth in Size
Library Building
Growth of Readers
Growth of Staff

8. ◦ faceted (or analytico-synthetic) classification system
◦ facets describe "personality" (the most specific subject), matter, energy, space,
and time (PMEST)
◦ There are 42 main classes of CC
◦ The devices - chronological, geographical, subject and alphabetical - used in
CC.
◦ The CC notation is mixed notation
◦ classification by dividing it in three succeeding phases, called Planes: (a) Idea
plane, (b) Verbal plane, and (c) National plane.
◦ the work in each plane is executed by 55 Canons, 22 Principles and 13
Postulates .
◦ provided a high potential for forming new isolates
◦ rich in hospitality.

10. ◦ first published in 1934.
◦ It has two parts 1. Classified part 2.alphabetical part
◦ This part contains alphabetical arrangement by authors, collaborators,
series, editor of series and titles. It gives rules for Main Entry, Class Index
Entries, Book Index Entries, Cross Reference Index Entries, for single
volume, multi volume, composite books, periodicals, national
bibliographies, union catalogue of books and periodicals, indexing and
abstracting periodicals.
◦ The foundation of the code is based on the normative principles.

12. Chain Indexing or Chain Procedure is a
mechanical method to derive subject index entries
or subject headings from the class number of the
document. It was developed by Dr. S.R.
Ranganathan. He first mentioned this in his book
“Theory of Library Catalogue” in 1938.
1.This procedure, i.e., chain indexing can be
applied with ease to any classification scheme
whose notational symbols indicate the
subordination of each step of division e.g. Colon
Classification (CC), Dewey Decimal Classification
(DDC), Library of Congress Classification (LCC), etc.

13. 2.Chain indexing saves the time of the
indexer, as he makes use of the class
number provided by the classifier, thus,
avoiding duplication of work, in analyzing
the document and the formulation of class
number.
3. Chain indexing provides alternative
approaches through reverse rendering to
its classified file
