The Dewey Decimal System
By Leigh Anne Black Smith
And Lisa Hughes
How are our books arranged? This presentation will help
you understand the Dewey Decimal Classification
system used in our media center.
WHAT IS IN THE MEDIA
CENTER AND WHY?
1. What is the system that is used to shelve nonfiction
books?
2. Who is the creator of this system?
3. How many categories are in this system?
4. What are the categories and how are they divided?
5. What do the different numbers and letters on the
spine of the book represent?
6. Does a short number or a longer number give more
information?
What is the Dewey Decimal System?
• The Dewey Decimal Classification (DDC)
system is the world’s most widely used library
classification system.
• The DDC was developed by Melvin Dewey in
1876 with 23 revisions as of 2011.
• DDC organizes books on library shelves in
numerical order, including decimals, to enable
users to retrieve and return books efficiently.
• All knowledge is organized into ten main
categories with sub-categories.
Category Classification
Numbering System
• The main classes are classified by hundreds, having
three digit numbers (ex. 001-099, 100-199, 200-299,
etc.)
• The ten classes are subdivided into ten divisions (ex.
010, 020, 030, and 110, 120, 130, etc.)
• Each division is further subdivided into ten sections (ex.
011, 012, 013 and 111, 112, 113, etc.)
• The DDC also classifies using decimal numbers for
more specificity beginning with the fourth digit with a
decimal placed after the third digit (ex 324. 3 or 324.
354, etc.)

DDC Sub-Category
Classification Numbering
• The main classification numbers are
divided into tens (Example: 010).
• The next sub-category within a subcategory divides the numbers into ten
again (Example: 011).
• The next level begins with a decimal
(Example: 011.6).
• The next level would involve using 2
decimal places (Example: 011.62) This
numbering system can continue infinitely
if needed.
