Guidelines for Recording Holdings: Extent of Unit

  • Extent of unit is usually given when a unit lacks enumeration and/or chronology.


  • Extent of unit is recorded as a count of the number of parts held followed by a term indicating the specific class of material.


    • If the number of parts appears on the container or the number is easily determined, give the exact number of parts


      1 v. [only used if unit also has accompanying material]
      2 sound cassettes
      1 disk
      50 playing cards + 10 green dots + 10 scorecards
    • If the number of parts does not appear on the container or the number is not easily determined, give an estimate of the total number of parts.


      ca. 500 pieces
