PreviousNext

Materials are assigned certain subject classifications. Usually, college and university libraries use the Library of Congress classification system. In this system, the classification letter A is used for general works, such as encyclopedias. Likewise,

  • B is for philosophy, psychology and religion
  • N is for fine arts
  • Q is for science

Other letters of the alphabet are assigned to other areas of knowledge.
