Policy and formulation

  • Include readily-available date information in this field, even if that information is not used in the authorized access point.
  • Firm (even if vague) dates do not need a ǂ2; it is assumed that the source is ISO 8601 (the international standard for dates and times).
  • Uncertain dates are formulated according to the Extended Date/Time Format developed by the Library of Congress, and require ǂ2 edtf

Examples
