Dewey Decimal System

How items are arranged in numerical order.

The Dewey Decimal System coordinates materials on the same subject and on related subjects to make items easier to find on the library shelves.  This system organizes information into 10 broad categories.  Each major category is divided into 9 sub-categories.  Each sub-category is further divided into 9 specialized topics that can be broken down even further by adding decimals.  Each division becomes more specific.
