Sterling Catalog   What's in it?  What's NOT in it?  Arrangement  Locating Materials
How do you Locate Material Found in the Catalog?
Material is arranged in each of the libraries on campus by location within the library and by call number.

For most materials shelving in the general bookstacks, call numbers are assigned based on their subject using classification systems which attempt to arrange all of human knowledge in large subject categories. Sterling has used two different classification systems:

  • Until 1970, it used the Yale system.
  • Since then, the Library of Congress system (LC) has been used.
  • The call number almost always appears in the upper left corner of the card.

    Since the first element in both classifications systems is a series of letters and numbers, Library of Congress call numbers are always clearly indicated by having the designation "(LC)" follow them on the card.

    Shelving in a location other than the Sterling stacks, whether in another library or in a specific collection in Sterling, is indicated by the name of the library or collection appearing above or below the call number. These location symbols always take precedence over location by call number.

    Shelving in the Sterling stacks is by size as well as classification. Size indications include:

    In the Yale classification:
  • Oversize works carry an initial "O" or a "+" as the first element of the second or third line of the call number.
  • Folio works carry a double initial "OO" as the first elelment of the second or third line of the call number.

    In the Library of Congress classification
  • Oversize works carry an initial "+" as the first element of the second or third line of the call number.
  • Folio works have the word "Folio" printed above the call number.
  • Use the Sterling stack directory to translate the combination of classification and size into a stack level location in the stacks.
