3. Introduction of DDC
 The Dewey Decimal Classification system is used in
Library classification that is continusly revised to keep
pace with current knowledge.
 This system first published in the United State of
America by Melvile Louis Kossuth Dewey in 1876. Melvil
Dewey ,the man who had this great idea for organizing
Library classification.
 The first editon of DDC consisted of only 42 pages at taht
time
 since 1876 to 2011 (23rd edition) this scheme did not look
back, and it is popularly has grown day by day through
out the world.
 it is translated more than 30 language.

4. Feature of DDC
 It has ten main classes (000-900 known as the ‘first
schedule’).
 These are further subdivided into units of ten (010-
900 known as the ‘second schedule’).
 These are then subdivided by ten ( so that the one
thousand division from 001-999 is known as the
‘third schedule’).
 10 Main classes (first schedule/first summary).
 100 Division (second schedule/first summary).
 1ooo Section (third schedule/first summary).

5. The schedules
 The schedule number include the start (or ‘base’
number ) of each DDC number.
 They range from 000 to 900.
The ten main classes are :-
 000 Generalities
100 Philosophy, Psychology
200 Religion
300 Social Science
400 Language

6. ….continue
500 Pure Science & Mathematics
600 Applied Science & Technology
700 The Arts
800 Literature
900 Geography & History
Two rules regarding schedule number-
1) Schedule numbers are never less than Three digit
number, and
2) A schedule number must never end with Zero
anywhere to the right side of decimal point
For example , use 512.31 NOT 512.310

7. The Tables :
There are Seven numbered Tables-
T1 Standard Subdivision ( Such as ‘ Encyclopedia’
or ‘ Periodical’ )
T2 Geographic areas, Historical periods, Biography
T3 Literature and Literary form
T4 Individual language & language families
T5 Racial, Ethnic and National group
T6 Languages
T7 Groups of Person
THE END

8. Introduction of UDC
 The Universal Decimal Classification scheme of
classification was developed in the year 1895 by the
Belgium Barrister Paul Otlet and Winer Henri La
Fountaine.
 The UDC is derived from DDC as universal since it
encompass the whole field of knwoldge.
 It is the multi-lingual general classification tool for
organizing all kinds of recorded knowledge in the
library.
 it is an international classification systyem mainly
developed for the purpose of indexing and arranging

9. ….continue
an enormous card bibliography which not only
includes books but also all kind of documents,
periodical article, patents, trade catalogues, abstracts
and other micro document in more than 28 different
international languages.

10. Features of UDC
1.UDC is a practical scheme based on the demands of
pamphlets, reports and periodical literature rather
than the framework of a theory.
2.The scheme is based on DDC and claims to be the
first Analytico-synthetic classification scheme.
3.It lays more stress to achieve co-extensive class
numbers i.e. detailed specification than the
achievement of a sequence of subjects for optimum
helpfulness.
4.It avoids the lacunae of numerous private
classification schemes by providing a standard
system covering all the disciplines and may be used
in any type of library.

11. Continue……
5.It is a general classification scheme and not a bundle
of special classification.
6.It is rather an integrated whole.The scheme reflects
exhaustive enumeration in the schedule with due
provision for synthesis or coordination.
7.It is amenable to adjustments to meet the special
needs because acitation order in any given class
allows alternative treatment.
8.The use of synthetic devices like colon (:), permits
coordination of concept in different permutation,
there by minimizing the rigidity in the enumerated
classification scheme.

12. Continue……
9.An International body for its maintenance and
revision with full cooperation of its users guarantees
the continual existence of the system as a current
and up-to-date one.
10.The terminology used in UDC helps in a
comprehensive vocabulary of terms for indexing
purposes.
