Did you check out March’s library book code? Here it is again:

Matthew's Decoder #2017-03

How It Works

Developed in 1876, the Dewey Decimal System organizes nonfiction books by topic. It’s how libraries keep track of the thousands of titles on their shelves. Each book receives a three-digit class number based on its subject:

000—General Information (encyclopedias or catalogs)
300—Social Science
700—Art and Sports
900—History and Geography

To crack this code, arrange the books left to right by class number. (Can’t tell where some books belong? Visit your local library.) Then read the red letter in each title.

Look for a new code in the next issue of Clubhouse magazine.
