It's Career Day at Marion's school and she can't wait to tell what career she is going to choose when she grows up. Willis goes first and tells everyone he's going to be a firefighter. When it's Marion turn, she announces she is going to be a librarian. Willis makes fun of her and says that being a librarian is really boring. Marion can't wait to teach Willis a thing or two about libraries. She invites him to go with her to the library and then starts revealing all the hidden treasures. First, there's the book that's better than a video game-it's all about Perseus. It's in the 200's. Marion takes Willis to the 400's and the 700's and all through the stacks teaching him how fabulous the different sections are. This is a great book for teaching the Dewey Decimal system.
