What Is a Call Number?

Library of Congress Classification System

Most books in the Mendik Library are arranged by the Library of Congress Classification System. The system divides all knowledge into twenty-one basic classes, each identified by a single letter of the alphabet. Most of these alphabetical classes are further divided into more specific subclasses, identified by two-letter, or occasionally, three-letter combinations.

For example:

Class K - Law

  • Library of Congress Classification: Class K -- Law
    • Subclass K - Law in general. Comparative and uniform law. Jurisprudence
      • Subclass KB - Religious law in general. Comparative religious law. Jurisprudence
