Each book in the library is assigned its own call number, such as PR 6302 C6 R56. This call number is assigned and connected to the subject matter of the book.

1. Begin your search alphabetically with the first letter of the call number. This book will be in the Ps.

2. Next look for the second character, either a letter or a number. The call numbers are separated into letter and number chunks, such as PR, then 6302, then .C6, then R56. Follow that sequence until you have located the book.

3. The call number ranges for each shelving unit can be found on the ends of the row. 

The WSU Library uses the Library of Congress Classification System to organize most of its books. The LCC system organizes books into twenty-one broad subject areas, which are represented by letters of the Roman Alphabet. Each letter and number in the call number signifies specific topics. For example, L is for Education, LC1036 will include books about Community Education.
