The Dewey Decimal Classification System How the Library is Organized
Melvil Dewey 1851-1931 • Melvil Dewey devised a system of organizing books which is used in many libraries. He divided books up into 10 main subjects, and then assigned these subjects a number. That way all the books on a topic would be together on the shelf.
THINK ABOUT IT! If books weren’t shelved this way, libraries would be in total chaos!
What is a Call Number? • Every book in the library is given a unique call number that is an address for locating the book on the shelf. • The call number is located on the spine of a book. • The call number is made up of two parts: the Dewey Decimal classification number and the first three letters of the author’s last name.
Fiction Books that are stories made up by the author. They are not true, but might be based on true events. Nonfiction Books that are about real things, people, events and places. They are true, except for fairy and folk tales in 398 and literature in the 800s. The Difference Between Fiction and Nonfiction
Nonfiction call numbers begin with a Dewey number, and then the first three letters of the author’s last name. Fiction call numbers begin with E or FIC or F, and then the first three letters of the author’s last name. It’s still a call number even though there are no numbers in it! 599 GIB E SEU FIC PAU Fiction and Nonfiction Call Numbers
FICTION CALL NUMBERS HAVE ONLY LETTERS! NONFICTION CALL NUMBERS HAVE NUMBERS AND LETTERS! + Just Remember…….
The Dewey System Has 10 Main Classes for Organizing Nonfiction Books.
Dewey and Decimals Think of a Dewey number as if it were dollars and cents! For example: 595.23 Comes Before 595.30 When in doubt, add a 0 (zero) to even out the digits after the decimal.
What Else Might I Find In My Library??? • Magazines • I-Can-Read Books • Beginning Chapter Books • Short Fiction • Series • Music • Books on Tape • Maps and Globes • Computers
Exploring Your Library • Try making a map of the library to show the following sections: Everybody, Fiction, Nonfiction, Biographies and Reference • Mark your favorite section on the map. • Include the circulation desk where you check out and return books. • Write down the name of the Library Technician who checks out your books.
