Classification: A method for grouping items together with similar qualities. The groups are often called categories or classes.

In the Dewey Decimal System of Classification, all nonfiction books are classified (grouped) by subject. So, books about similar subjects are placed together on the shelf. Tigers Big Cats African Big Cats

Melvil Dewey invented the Dewey Decimal System of Classification in 1876. Brilliant!

Classification Systems are used in many places you visit, such as grocery stores.

• Classification systems help keep items organized.

How the System Works Dewey came up with 10 Main Classes for organizing books. He assigned a number and a subject for each of the main classes.

10 Main Classes 000 s - Generalities 100 s - Philosophy & Psychology 200 s - Religion 300 s - Social Sciences 400 s - Language 500 s - Natural Sciences and Mathematics 600 s - Technology 700 s - The Arts 800 s - Literature 900 s - Geography and History

So remember. . …library books have class!

Then, he subdivided each class into divisions of 10 s and gave them names. For example, the 500 s class: 500 Natural Sciences and Mathematics 510 Mathematics 520 Astronomy 530 Physics 540 Chemistry 550 Earth sciences & geology 560 Fossils & prehistoric life 570 Life sciences; biology 580 Plants (Botany) 590 Animals and Insects (Zoology)

Then, he subdivided each division into sections and gave them names: 590 591 592 593 594 Animals & Insects Body Systems of Animals and Insects Invertebrates , Worms Sea Invertebrates, Coral Mollusks, Octopus, Squid, Snail 595 Insects, Spiders 596 Vertebrates 597 Fish, Amphibians, Frogs, Snakes 598 Reptiles and Birds 599 Mammals of the Land Ocean

Then, he added decimal points and more numbers for very specific subjects. 597. 51 597. 52 597. 53 Fish with moveable upper jaws Moray eels Carp Sea Horse Book Sea Horses By Sam Smith Dewey Decimal number is typed on a label and placed on spine of the book. 597. 53 SMI

The spine labels on the books guide the order for placing books on a shelf! The books are shelved in Dewey/Alphabetical order. 597. 5 JEN 597. 51 KIN 597. 52 MOR 597. 53 SMI How nice to have all the fish books together on the shelf!
