Every Monday, we’ll see what book Dewey is reading! Over the summer, all Dewey’s books will be nonfiction science books in honor of the Fizz Boom Read Summer Reading Program! And since Dewey is named in honor of Melville Dewey, the creator of the Dewey Decimal System of Classification, we will learn a bit about how the Dewey Decimal System works, too!

So, what’s Dewey reading today…?


Dewey’s reading Natural Disasters: Investigate Earth’s Most Destructive Forces by Kathleen Reilly! This book’s call number is J 550 Reilly. Librarians read the call number as J five fifty (not five hundred fifty). The number 550 tells us that this book is about Earth science. Earth science is a vast topic! The 550s contain books on geology (551), weather (551.5), hurricanes (551.552), tornadoes (551.553), minerals (552), and gems (553.8) and more. Notice how the numbers after the decimal point help narrow a topic: weather 551.5 → hurricanes 551.552 or tornadoes 551.553.
