Locating Call Numbers

What are Call Numbers for

Each book in the library has a unique call number. A call number is like an address: it tells us where the book is located in the library.  Call numbers appear on the spine of the book and in online library catalogue.

Note that the same call number can be written from
top-to-bottom, or left-to-right

Ewing Memorial Library uses Dewey Decimal Classification for call numbers to arrange its collections. This system uses numbers to arrange materials by subjects.
