Good Morning, everyone! We’re back with a new trivia question for you!

All the books in your local library, as well as any other type of media they have to lend, have their own code of letters and/or numbers. If you look the code up in the library catalog, you can find out where the book is located. What is the name of this identifier?

Last week’s answer for you:

The Harry Potter series took “Top Prize” as the most commonly banned books by the American Library Association from 2000 to 2009.
