Dewey

=Dewey Decimal System=

The non-fiction books in the library are organized using the Dewey Decimal System (Dewey). Dewey is a classification system which uses numbers to organize books into different categories. The numbers go from 000 to 999.99. Within each hundreds grouping, the category is broken down into sub-categories. For example, the 400 category is languages and a book on Latin can be found at 470. Similarly, we know that Arts and Recreation books can be found in the 700's and books about soccer can be found at 796.

The 10 major categories of the Dewey Decimal System are:
