Using the Library & Dewey Decimal System
Lesson 3 in Detective Booksy's Library and Research Curriculum
Today’s mission is all about libraries—the treasure chests of knowledge—and a special system called the Dewey Decimal System that helps us find information quickly and easily. Are you ready to explore?
What Is a Library?
A library is like a treasure chest, full of books, knowledge, and resources waiting to be discovered. You’ll also find computers, research tools, and friendly librarians who can help you. Libraries are carefully organized to make it easy to find exactly what you need. Let’s take a closer look!
Why Use the Library?
Libraries are amazing places to find trustworthy information. Whether you’re researching animals, space, history, or anything else, the library has books and resources to help. And don’t forget—librarians are your research partners! They’re there to help you solve your mysteries.
What Is the Dewey Decimal System?
Have you ever wondered how libraries keep all those books organized? That’s where the Dewey Decimal System comes in! It’s a way to organize books by giving them numbers based on their subjects. It was created by a librarian named Melvil Dewey in 1876, and it’s still used today!
How Does the Dewey Decimal System Work?
The Dewey Decimal System works by dividing books into 10 main categories, each with its own number range, from 000 to 999. For example, books about animals are in the 500s, and books about art are in the 700s. These numbers help you find books on the shelves quickly.
The 10 Main Categories
Here are the 10 main categories of the Dewey Decimal System:
000: General Knowledge
100: Philosophy and Psychology
200: Religion
300: Social Sciences
400: Language
500: Science
600: Technology
700: Arts and Recreation
800: Literature
900: History and Geography
Each category is like a big umbrella with books on similar topics grouped underneath.
Finding a Book Using Dewey Decimal Numbers
Finding a book is easy! First, search for the book in the library catalog—a computer or a card system can help. Then, write down the Dewey Decimal number. Finally, use that number to locate the book on the shelf. It’s like following a treasure map!
Practice Time!
Now it’s your turn, detectives! Visit your library and pick a topic you love. Find a book on that topic, write down its Dewey Decimal number, and share your discovery with a friend or teacher. Libraries are full of treasures—go find yours!
Fun Fact About the Dewey Decimal System
Here’s a fun fact: The Dewey Decimal System is used by libraries all over the world! It organizes more than 1 billion books and has been helping people for over 140 years. That’s a lot of knowledge!
