					  The Dewey Decimal System
was created by Melville Dewey in
             1876
   What is the Dewey Decimal
            System?
• A system to organize books on library
  shelves so that they are easily found
  when needed.
• Decimal is a Latin word that means 10
• Melville Dewey decided that all
  knowledge would be described in 10
  main sections
How does the Dewey Decimal
      System Work?
Think of it as a code that uses numbers
 to help you find the book you want.
Each non-fiction book is put in a certain
 group and given a 3 digit number
 depending on the subject of the book.
There are 10 basic Dewey sections or
 categories .

           System
    Each of the 10 Dewey
categories is then divided into
        subsections.
• For example 700 (Arts and recreation) is
  subdivided into the following subsections:
     •   710 Civic & landscape art
     •   720 Architecture
     •   730 Plastic arts, sculpture
     •   740 Drawing & decorative arts
     •   750 Painting & paintings (museums)
     •   760 Graphic arts, printmaking & prints, postage stamps
     •   770 Photography & photographs
     •   780 Music
     •   790 Recreational & performing arts
  What each number means?
Let’s look at the call number 743.
 The 7 is the first number which tells you
  which of the 10 main Dewey categories the
  book belongs to- Arts and Recreation.
 The 4 is the second number which tells you
  which of the subdivisions it belongs to-
  Drawing and decorative art.
 The 3 provides even more specific
  information about the subject matter-in this
  case it is a book about drawing a specific
  subject.
743 AME

    • This book has
      the call number
      743 AME (AME
      stands for the
      first 3 letters of
      the author’s last
      name-Ames)
Do I have to memorize all the
categories to locate the book I
            want?
              Absolutely not!
 That’s why we have our new Catalog
 System which allows you to search by
  keyword and subject. In addition, the
  Dewey Decimal Numbers are labeled
        on the end of the shelves!
What if I can not find the book
   even if I know the call
           number?
                   Ask the
                    librarian
                    for help!
                   That is
                    why we
                    are
                    here!
