The library follows a method in arranging its books. This is known as the Dewey Decimal classicication. It was created by a librarian in 1876 named Melvil Dewey. This system divides topics into ten classes from 0 to 9.Under each class, certain subjects are written to further specify what the topic includes. They are as follows:

000-099 General Works(encyclopedia,periodicals)
100-199 Philosophy(psychology,conduct,etc.)
200-299 Religion(mythology)
300-399 Social Sciences(economics,government)
400-499 Language(dictionaries,grammar,etc.)
500-599 Science(math,chemistry,physics)
600-699 Useful Atrs(agriculture,engineering,etc.)
700-799 Fine Arts(sculpture,music,etc.)
800-899 Literature(poetry,novels,etc.)
900-999 History(geography,biography,etc.)

In the shelf in each book, there's a call number attached. It consists of a set of letters and numbers.The call number can also be seen at the upper left-hand corner of the cards in the card catalog. The call number can help you locate the book that you need by just knowing the number on where it belongs. Another thing is if ever you're having a hard time finding a book in a large library, you can just copy the call number of a book from a card catalog and give it to the librarian, who would be glad to help you.

The card catalog is the best way to easily find a book. It is made up of various drawers where certain alphabetically arranged cards are placed inside each compartment. The cards inside the drawer represents a book. In each book,there are 3 types of cards:the author,subject and title cards.

The author card show the author's name at the top including the other books he has written. The title card has the book's title at the top which are alphabetically arranged based on the first word of the title. The subject card contains the topic the book talks about.
