This page will provide an introduction to understanding and using library call numbers. Each book in the library has a unique call number. Al-Quds University Library, like many academic libraries in the world, uses Library of Congress Classification for call numbers. This system uses a combination of letters and numbers to arrange materials by subjects.
Call numbers can begin with one, two, or three letters.
The first letter of a call number represents one of the 21 major divisions of the LC System . All books in the LB's are primarily about the Theory and Practice of Education. Books in categories E, United States History, and F, Local U.S. History and American History, do not have a second letter. All other subject areas will have call numbers beginning with one or two letters. Numbers after letters.
