2 What is a shelf number and why is it important?  It is the number that appears on the spine of a book  A shelf number can also be called a call number or class number  It consists of 2 parts, namely the Dewey Decimal Classification number and a suffix of 3 letters  The suffix are usually made up of the first 3 letters of an author’s surname or the title  The shelf number can be seen as the “address” of the item  It is important because it groups together materials on the same subject and on related subjects to make items easier to find on the shelves

3 Dewey Decimal Classification : a history  The Dewey Decimal Classification System was developed to bring order in the Library and to promote easy access  Melville Dewey published the first Dewey Decimal Classification System (DDC) in 1876  Today we are using the 22nd edition of Dewey’s classification

4 What is a DDC number?  According to the DDC system each item in the Library is given a DDC number  The number given depends on the subject field that the item covers MAIN OS 658 MAN MAIN OS 658. 022 SMA MAIN OS 658. 15 FIN MAIN OS 658. 8 MAR MAIN OS 659 ADV

5 DDC : divided into 10 main classes 000Generalities 100Philosophy & Psychology 200Religion 300Social Science 400Language 500Natural Science & Mathematics 600Technology 700Arts 800Literature 900Geography & History

6 Division of the 10 main classes The 10 main classes each have ten divisions Each of the divisions are further divided, which makes it more specific As the number expands it moves from the general to the specific DDC uses the decimal place to make the number even more specific

7 Example To find the classification number for personnel management we need to start with the class for Technology (Applied Sciences), 600’s Therefore, the first number of the shelf number will be 6 The 10 divisions of the 600’s is: 600Technology 610Medical Sciences 620Engineering & Allied operations 630Agriculture & Related technologies 640Home economics & Family living 650Management & Auxiliary services 660Chemical engineering 670Manufacturing 680Manufacture for specific uses 690Buildings

8 …example continue Personnel management will be classified under “Management and Auxiliary services” 650 Now we know the second number of the shelf number will by 5 Let’s see the divisions of the 650's to find the next number : 651Office service 652Processes of written communication 653Shorthand 657Accounting 658General Management 659Advertising & Public relations

9 …example still continuing Business Management, including Personnel Management, would be under 658 The 658’s are further divided by the use of decimals to specify what type of management 600 – Technology (Applied Science) 650 – Management & Auxiliary Services 658 – Business Management 658.3 – Personnel Management
