3. ☻ Libraries deal with the knowledge and
mission of the libraries is the knowledge
management.
☻ The Dewey Decimal Classification (DDC)
is a proprietary library classification system
created by Melvin Dewey in 1876.

4. ☻ It has been revised and
expanded through 23 major
editions, the latest issued in 2011.
☻ It has been adopted in all 5
continents of the world.
☻The DDC is a system of library
classification made up of ten
classes, each divided into ten
divisions, each having ten
sections .

5.  A map is a visual representation of
an area – a symbolic depiction
highlighting relationships between
elements of that space such as
objects , regions , and themes.
 In mathematics: “ Map is often a
synonym for function “
 Mapping usually refers to map -
making and often used instead of
cartography

6.  Mapping term is also
sometimes used for
geospatial data collection
 Mapping a strategic "road
map" for execution of plans

7. 
In DDC, the whole of
knowledge is divided each
of these into ten sub
divisions, then each of the
sub divisions into ten
sections .

Hence, the term decimal
classification.

8. 000 – Computer science, information and
general works
100 – Philosophy and psychology
200 – Religion
300 – Social sciences
400 – Language
500 – Science (including mathematics)
600 – Technology and applied science
700 – Arts and recreation
800 – Literature
900 – History and geography

9.  The notation of DDC is
beautifully simple and pure.
 A base of ten has become the
major characteristics of DDC.
 Major characteristic of the
notation is it’s hierarchical
structure.

10.  600 Technology
630 Agriculture and related technologies
636 Animal husbandry
636.7 Dogs
636.8 Cats
“Dogs” and “Cats” are more specific than (i.e., are
subordinate to) “Animal husbandry”; they are
equally specific as (i.e., are coordinate with) each
other; and “Animal husbandry” is less specific than
(i.e., is super ordinate to) “Dogs” and “Cats.”

11. The seven tables are :
 standard subdivision
 areas
 subdivision of individual literatures
 subdivisions of individual languages
 racial, ethnic, national groups
 languages
 persons

12.  A table of notations designing certain
frequently recurring forms or methods
of treatment applicable to any subject.
For e.g. :
540 Chemistry
-09 History ( Table 1)
History of Chemistry 540.9

13.  A table of notations designing geographical
areas.
For e.g. :
327 Foreign relation
-54 India (Table 2)
-52 Japan (Table 2)
327.54052 Foreign relation
between India and Japan

14.  This table is used with notations from
the literature class (Class 800).
For e.g. :
84 French literature
-08 Collections of literary text (Table 3B)
840.8 Collections of French literature

15.  This table is used with notations
from the language class (Class
400).
For e.g. :
44 French language
-15 Phonology ( Table 4)
441.5 French Phonology

16.  The notation from this table may be
used with those numbers from the
schedules and other tables to which
the classifier is instructed to add.
For e.g. :
738 Ceramic arts
-089 Racial,Ethnic,National groups
( Table 1)
-951 Chinese ( Table 5)
738.089951 Ceramic arts of Chinese

17.  The notation from this table may be
used with base numbers from the
schedules and other tables to which
the classifier is instructed to add.
For e.g. :
220.5 Translation of Bible
-31 German language ( Table 6)
220.531 Translation of Bible in German language

18.  The table is used to denote group of
persons
For e.g. :
-024 Works for specific type of users ( Table 1)
510.24 Mathematics
-62 Engineers ( Table 7)
510.2462 Mathematics for Engineers

19.  DDC is discipline oriented scheme
 The DDC is a system of library
classification made up of ten classes,
each divided into ten divisions, each
having ten sections
 The notation of DDC is beautifully
simple and pure
 The scheme is hierarchical , like a
family tree
