Understanding Call Numbers



The most frequently use classification systems are :

  • Dewey Decimal Classification System (Dewey) - Used by most public and school libraries.
    Dewey call numbers begin with a three digit number.
    In the online catalog, typical Dewey call numbers look like:
    • 813 AL355L 1987

    On book spines, or labels on other materials, Dewey call numbers are arranged vertically and would typically look like:
    • 813
      AL355L
      1987

  • Library of Congress Classification System (LC) - Used by most academic libraries and in other larger libraries.
    LC call numbers begin with letters.
    In the online catalog, typical LC call numbers look like:
    • PS 1017 .L5 1983

    On book spines, or labels on other materials, LC call numbers are arranged vertically and would typically look like:
    • PS
      1017
      .L5
      1983

  • Superintendent of Documents (SuDocs) - Used by libraries with extensive collections of materials published by the United States Government
    SuDocs call numbers begin with letters and always include a colon.
    SuDocs call numbers typically look like:
    • HE 20.3002:R 24/5

Libraries may use one or all of these systems, based on the collections they own.

LSU Libraries use all of the above systems, as well as some other classification systems which are specially suited to certain special collections.
