The document explains the Dewey Decimal System, which was invented by librarian Melvil Dewey to categorize nonfiction books into 10 main subject groups represented by 3-digit numbers. It details the 10 groups which include general works, philosophy, religion, social sciences, language, science, technology, arts, literature, and history. Each group contains more specific subcategories also represented by 3-digit numbers to help library patrons easily find books on their desired subjects.

3. Now let’s learn more
about the numbers in
a nonfiction call
number.

4. How do we know
what number goes
with each subject ?
By using something cool called
The Dewey Decimal
System !!

5. The Dewey Decimal
System is a tool used
to sort books into
groups or
categories

6. This system was
invented by a man
named Melvil Dewey.
He was a
librarian who
lived long ago.

7. Sorting books by

brilliant idea!!
I think I’ve got it !!

8. 10 general groups
for sorting all of the
subjects
General means broad,
lots of subjects will fit
into each group.

9. Here are the 10 general
groups for sorting books in
the Dewey Decimal System:
General Works Philosophy
Religion Social Studies
Language Science
Technology Arts and Leisure
Literature History/Geography

10. This seems like a
lot to remember,
but don’t worry
you’ll learn it all
quickly.
So let’s get going !!!!

11. 000s-General Works
Books that fit in this group
have many different
subjects in them. Like:
Encyclopedias or The Guinness Book of
Records
This is also where books on
unexplained subjects would be
found-like The Loch Ness Monster.

12. 100s-Philosophy
Books that fit in this group
tell about how we think and
feel.

in this way, so fiction
books have their own way
of being organized.
You know, in ABC order, by
author !

groups will help make
it easier to find the
books you want in the
nonfiction section.

numbers are placed in
number order first, so
that means all of the
