The document discusses the Dewey Decimal System, which was invented by Melvil Dewey to categorize books into 10 main subject groups represented by 3-digit numbers. It explains the general categories including 000s for general works, 100s for philosophy, 200s for religion, and so on up to 900s for history and geography. Nonfiction books are organized on shelves first by their Dewey Decimal number, which helps readers find books on the same subject near each other.

1. The Numbers in Nonfiction

2. We have learned the recipe for making a nonfiction call number. numbers (for the subject) first three letters of the author’s last name

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 subject, what a 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.

13. 200s-Religion Books in this group tell about different religions or stories from the bible.

14. 300s-Social Studies Books in this group tell about how people live together. holidays and customs government, military

15. Fairy tales and folk tales are also placed in the 300s. Many were written to teach a lesson about behavior and.. That’s social studies.

16. 400s-Language Books in this group are about different languages or grammar. noun verb adjective

17. 500s-Science Books in this group are about things from nature.

18. 600s-Technology This group has books that are about man-made things.

19. 700s-Arts and Leisure Books in this group are about things we do for fun.

20. 800s-Literature Books in this group are stories, plays, or poetry. This is the group fiction books were put in long ago when The Dewey Decimal System was first invented.

21. Today we have too many fiction books in our libraries to organize them in this way, so fiction books have their own way of being organized. You know, in ABC order, by author !

22. 900s-History/Geography Books in this group tell about events of the past and countries of the world.

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

25. Remember, nonfiction call numbers are placed in number order first, so that means all of the books about the same subject end up near each other on the shelf. That’s Smart !!!!
