Call Numbers: The Basics

by PSL Law Library 12. September 2013 14:33

 

Call numbers are derived from a classification system used by libraries to organize materials into classes (subjects) so like materials are shelved together.  Our Library uses the Library of Congress Classification System which is often used by academic libraries in the United States and other countries.  You may be more familiar with the Dewey Decimal Classification System, most often used by public libraries.  You can find call numbers on the spine or cover (lower left corner) of the material.  Call numbers also appear in the results list and item records in the catalog.  If an item in the catalog doesn’t have a call number then it’s an online resource.

The call number can be narrowed into very specific subjects:
a. K is for Law
b. KF is for Law in the United States
c. KF801 is for Contract Law in the United States
d. KF801.A7 is for Casebooks on Contract Law in the United States
e. KF801.Z9 is for Study Aids on Contract Law in the United States 

Now that you know what a call number is you can use this information to locate materials in any academic library.  Find study aids on Contracts in any collection (or library) by looking for items with the call number KF801.Z9.  Many call numbers contain the publishing date to help ensure you select the latest edition.  Glannon Guide to Contracts, KF801.Z9 S49 2013 was published in 2013.  Finally, find a greater number of materials on a subject by looking for materials with similar call numbers.

*For more information on call numbers please refer to the library maps located at the Research Desk.
