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 Space Encyclopedia: a Tour of Our Solar System and Beyond by David Aguilar! This book’s call number is J 523.1 Aguilar. Librarians read the call number as J five twenty-three point one (not five hundred twenty-three point one). The number 523 tells us that this book is about celestial bodies – that’s a fancy way of saying planets, stars, moons, etc. The .1 helps us narrow the topic of all celestial bodies to something more precise – in this case, the universe or galaxy. Although, the universe is still a very large topic! Since this book’s title mentions “our solar system” we know that the .1 narrows the topic to our solar system.
