DDC Mapping of Knowledge

1. “ MAPPING OF KNOWLEDGE in DDC ”

2. 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.

3. 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 .

4. 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

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

6. 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.

7. The classes are: 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

8. 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.

9. For example , 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.”

10. TABLES The six tables are : Table 1: Standard subdivision Table 2: Areas Table 3: subdivision of individual literatures Table 4: subdivisions of individual languages Table 5: racial, ethnic, national groups Table 6: languages

11. 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

12. 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

13. 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

14. 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) 441.5 French Phonology

15. 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

16. 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

17. 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

18. 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
