INTRODUCTION

☻ 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.

☻ 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 .

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

Mapping term is also sometimes used for geospatial data collection

Mapping a strategic "road map" for execution of plans

MAIN CLASSES

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.

The classes are:

000 – Computer science, information and general works

100 – Philosophy and psychology200 – Religion300 – Social sciences400 – Language500 – Science (including mathematics)600 – Technology and applied science 700 – Arts and recreation800 – Literature900 – History and geography

Notation

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.

For example , 600   Technology

630      Agriculture and related technologies636       Animal husbandry636.7        Dogs636.8        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.”

TABLESThe seven tables are :

standard subdivision areas subdivision of individual literatures subdivisions of individual

languages racial, ethnic, national groups languages persons

Table 1 - Standard subdivision

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

Table2 - Areas 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

Table 3 – Subdivisions of individual literatures

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

Table 4 – Subdivisions of individual languages

This table is used with notations from the language class (Class 400).

For e.g. : 44 French language-15 Phonology ( Table 4)441.5French Phonology

Table 5 – Racial,Ethnic,National groups

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

Table 6 – Languages 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

Table 7 – Persons

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

CONCLUSION

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
