  1. UNDERSTANDING CALL NUMBERS Each book in the library has a unique call number. A call number is like an address: it tells us where the book is located in the library. Call numbers appear on the books and in the OPAC, the library catalog.

  2. Dewey Decimal System - DDC uses a system of numbering and classifies books by topic used by most public schools Two types of systems are used for call numbers: Library of Congress Classification System – LCC uses a combination of letters and numbers and classifies books by subject used by many academic libraries

  3. Did you know that your library has a great way of organizing its books so that you can find them easily? Get to know the DDC

  4. It’s called the Dewey Decimal Classification system—or DDC. This system got its name from Melvil Dewey (1851-1931), who introduced his great idea for organizing library collections in 1876. Melvil Dewey Get to know the DDC

  5. The DDC helps libraries arrange the items so that library users can find them. It’s a lot like an organized kitchen pantry: • Canned goods on one shelf • Breakfast cereals and grains on a second shelf • Baking goods on a third shelf • Snacks on a fourth shelf Get to know the DDC

  6. You will probably notice that when you find a specific book, other books shelved around it are usually books on a similar topic. That’s how the DDC is arranged—by topic. The DDC has lots of topics— thousands of them! Get to know the DDC

  7. The topics in the DDC are arranged into ten main classes: 500 Science 600 Technology 700 Arts & recreation 800 Literature 900 History & geography 000 Computer science, information & general works 100 Philosophy & psychology 200 Religion 300 Social sciences 400 Language Get to know the DDC

  8. These ten main classes are each divided into ten divisions, like this: • 700 Arts • 710 Landscaping & • area planning • 720 Architecture • 730 Sculpture, ceramics • & metalwork • 740 Drawing & decorative • arts 750 Painting 760 Graphic arts 770 Photography & computer art 780 Music 790 Sports, games & entertainment Get to know the DDC

  9. Each division is then divided into ten sections, like this: 795 Games of chance 796 Athletic & outdoor sports & games 797 Aquatic & air sports 798 Equestrian sports & animal racing 799 Fishing, hunting & shooting 790 Recreational & performing arts 791 Public performances 792 Stage presentations 793 Indoor games & amusements 794 Indoor games of skill Get to know the DDC

  10. You’ll see all of these numbers on the LEFT side of the decimal point. But what about the numbers on the RIGHT side of the decimal point? • 796.046 Get to know the DDC

  11. The numbers on the right side are used to • divide a specific subject into even more • specific parts of a subject. • For a book on 16th century Italian poetry, look for 851.4 • For a book on dog training, look for 636.70887 • For a book on extreme sports, look for 796.046 • It’s like sorting your socks by color, or music CDs by performer or type of music. Get to know the DDC

  12. So how do you know what numbers to look for • in the first place? Here are a few suggestions: • You can look up your topic on a computer in your library. • You can browse the shelves, using the DDC numbers on the ends of shelves as your guide. • You can ask someone who works at the library to help. Get to know the DDC

  13. Melvil Dewey had a great idea in 1876 that helps library users like you today. You can count on his idea, the DDC, to help you find the information you need in your library. Melvil Dewey Get to know the DDC

  14. The Library of Congress Classification (LCC) was first developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress.

  16. What does the call number mean? The first sections of the call number represent the subject of the book. The letter-and-decimal section of the call number often represents the author’s last name. The last section of a call number is often the date of publication. FOR EXAMPLE:
