Melvil Dewey livedan extraordinary life! He was born in Adams Center, New York, onDecember 10, 1851,and died onDecember 26, 1931.
He was a librarian who invented adecimal classification system for library books called theDewey Decimal System.

In 1876, he founded the American Library Association and published the first Library Journal,which includednew library trends and book reviews.Melvil opened the first library school in 1887 located at Columbia University.


Before we get startedwe're going to do a quick review.We are going to coverthe difference betweenfiction and non-fictionand how to organize them.We will also discusscall numbersand what they look like.


Nonfiction - is the opposite of fiction.

Books that are nonfiction, or true,are about real things, people,events, and places.


Still confused?

Well, here's another way to remember it:You can only say no once.Fiction = not trueNonfiction = true


Fiction books are put on the shelf inalphabetical order bythe author's last name.

Let's pretend you wrote a book and your last name was Cleary.  If kids liked your book, they would want to read more of them, so by having your books in the same place it would make finding them a lot easier.


Non-Fiction books are shelved by their subject's category

For example, if you wanted a book about cars, you would want them to be in the same area.  You wouldn't worry about the author, you would just want the facts about cars.


A call number

is a group of numbers and/or lettersput together to tell youwhere in the libraryto find your book.A call number is locatedat the bottom of the book on the spine.It helps you to find your books quicker.Once you've got your call numberfrom the card catalog, it's time to go find your book!


This is where a

call number is located:


Here's something to remember:Don't let it confuse you, but just because it's a call number doesn't mean it has numbers!  Some call numbers are made up of letters.I'll show you some examples later.


Now, if you're having trouble finding your book on the shelf,

remember this rule forhow the books are shelved: left-to-right, top-to-bottom


That means you start at the left on the top shelfand move to the rightuntil the shelf ends.Then, you go to the next shelf beneath thatand do the same,left to right, top to bottom.


When you get to the end of the bottom shelf,

move up to the top shelf of the next section,and continue...

what does a fiction call number look like
What does a FICTION call number look like?

We have been talking about call numbers a whole lot.One thing we have not taught you is what a call number looks like.We need to teach you how fiction and Dewey call numbersare different.

F = FictionMcD = first 3 initials of theauthor's last name


Next, there is the call number that we use for nonfiction books and that is theDewey Decimal Number.A Dewey call  number always hasthree numbersto the left of the decimal. 

To the right of the decimal, there is no limit on number.

The more numbers you add to the right of the decimal,the more specific the subject is.


We are going to tell you how to remember what each of the Dewey hundreds groups represents.

One day, while Melvil Dewey was walking in Central Park, he saw a UFO.  He became terrified of it, and ran to take cover.


The UFO approached Central Park with a loud noise and bright lights surrounding it.  A weird looking creature stepped out of the space craft.  Dewey got up from the ground and peeked out from behind a tree.


They stood staring at each other, and then they got up enough nerve to ask:

We think  about ourselves:  100s - Psychology and Philosophy


Melvil and the alien looked at each other with puzzled expressions and noticed how different they were from each other.  As they stood, they wondered to themselves:


Dewey realized that the alien's world must be very different from the United States.  He decided to take him to learn about our government.


Dewey knew that the alien would  need to learn how to communicate with people.

400s - Languages

We communicate with each other


Dewey and the alien began to stroll around, and Deweyexplained life on Planet Earth.

We learn about Nature and the world around  us:

500s -  Natural Science.


Dewey explained to the alien that humans have changed Nature to make life easier.

How we can make Nature useful?  600s - Applied Science


Dewey explained to the alien that technology has made life easier on Planet Earth.  It gives us more free time to do what we want.  Dewey and the alien took a spare moment to shoot hoops.

700s - Fine Arts and Recreation


Dewey and the alien had a fabulous day.  He invited the alien to visit the library where he worked.   Dewey gave him a tour of the library and explained how his decimal classification system worked.

While there, they decided to make a memory of their day on Planet Earth by making a scrapbook.  They wrote what will become history sooner or later - their day together!

900s - Geography and History


As the Alien prepared to leave, he told Dewey, "When I get backto my planet, I want to group all my books in this new awesome way.  But, which hundred group should I put my scrapbook in?"Dewey replied, "That's easy!  You would put it in the 000s - General Works.  That's where we put encyclopedias because they contain so much information that you can't describe them in one category!"

000s - General Works - Encyclopedias, books about libraries,museums, journalism, computers, and controversial or unexplained topics.
