The Dewey Decimal System is used to find the location of a print book in the library.
The Dewey Decimal Number is displayed on the spine of the book.
A list of Dewey Decimal Numbers are found at the end of each row of shelves, signifying which Dewey Numbers are stored in that row.
This floor plan of the Info Zone of the library also shows where books are located arranged by their Dewey Number.
