6. DEWEY DECIMAL CLASSIFICATION
SYSTEM (DDCS)
The Dewey Decimal Classification System is the most widely
used method for classifying books in the library. This system is
a general knowledge organization tool that is continuously
revised to keep pace with knowledge. It is named after Melvil
Dewey, an American Librarian who developed it in 1876. This
system is a numerical scheme for the arrangement of subjects
of nonfiction books, and it classifies books by dividing them
into 10 main subject groups that are called categories. Each
category is represented by figures beginning with 000 and
going on to 999. In other words, it is a system of numbers used

7. The Dewey Decimal Classification System is used
in most Public School libraries. It is essential for
students to understand why books are numbered
and how to find the numbers on the shelves, so
they can use the library effectively and in a
friendly manner. Dewey is also used for other
purposes, e.g., as a browsing mechanism for
resources on the Web. One of Dewey's great
strengths is that the system is developed and
maintained in a national bibliographic agency, the

9. Each number stands for a special topic. Every book is given a
number and is put on the shelf in number order.
Books with the same number are put in alphabetical order
by the author’s last name.
 There are three summaries of the DDC number represents
the main class.
For example: 500 represents natural sciences and
mathematics.
The second summary contains the hundred divisions. The
second digit in each three-digit number indicates the
division.
For example, 500 is used for general works on the sciences
510 for mathematics

10. The third summary contains the thousand sections. The
third digit in each three-digit number indicates the section.
Thus, 530 is used for general works on physics
531 for classical mechanics
532 for fluid mechanics
533 for gas mechanic.
A decimal point follows the third digit in a class number,
after which division by ten continues to the specific degree
of classification needed. A subject may appear in more than
one discipline.
For example, "clothing" has aspects that fall under several
disciplines. The psychological influence of clothing belongs
in 155.95 as part of the discipline of psychology; customs
associated with clothing belong in 391 as part of the
discipline of customs; and clothing in the sense of fashion

11. CARD CATALOG- a set of cards in a

contains all of the
same information
that the author

but the information
is rearranged on
each card entry.
The title of the book
is listed, then the
