Where on earth is that book?
Forget the internet! If you need to know something, it's bound to be in a book. And chances are that you'll find a book with the information you need in your school or public library.
Did you know that all over the world libraries categorise books in the same way? That means they use the same system in Scotland, Brazil, India, China and any other country you can think of! If you know this system, it means that you can go into a library and find a book wherever you are.
In this unit you'll learn how books are categorised in libraries, and how to find the book you need. Then you'll always be at home in a library, even when you're away from home!
