1. “Doing DEWEY” The Dewey Decimal System Library Skills Mrs. Geist

2. Do you have a lot of books? What if you had 100 more? What if you had 10,000 more? Where would you PUT them? How would you keep track of them?

3. Now imagine that this whole building is a library, with books filling each room instead of classrooms. If you need a dictionary, which room would you go to?

5. WHERE IS THAT ONE BOOK THAT YOU NEED???

6. Librarians need to know what books are in the library and where they are located. So do you. Most school and public libraries use a numerical system to arrange books on the library shelves…

7. The Dewey Decimal Classification System! (or DDC for short)

8. What have we learned about how books are arranged in this library? Fiction = Books that are not true (Novels, stories, picture books, scary books, chapter books, mysteries, fantasy books, books in series, etc.) Arranged on shelves ALPHABETICALLY by the AUTHOR’S LAST NAME. Call number is “F” followed by first letters of Author’s last name.

9. For example, F CAB is the call number for The Princess Diaries by Meg Cabot. F ROW is the call number for Harry Potter and the Sorcerer’s Stone by J. K. Rowling.

10. NONFICTION = Books that are TRUE, factual, or real. Arranged on shelves using Dewey Decimal Classification System Arranged on shelves using Dewey Decimal Classification System Includes biographies, reference books, textbooks Includes biographies, reference books, textbooks Call number is a series of at least 3 numbers, followed by a “cutter” of the first letters of author’s last name. Call number is a series of at least 3 numbers, followed by a “cutter” of the first letters of author’s last name.

11. For example: 031 Gui -- Guinness Book of World Records 636.7 Bar -- The Big Book of Dogs 973.75 Dou-- The Civil War in Virginia

12. *To confuse matters, SOME “nonfiction” books are actually fiction! Fairy tales are shelved in 398’s. Poetry and plays are shelved in 800’s

25. A library book is assigned a Dewey call number of between 001 and 999 based on its subject. A library book is assigned a Dewey call number of between 001 and 999 based on its subject.
