Expression

Expression is used only for dates or date spans spelled out in full year/month (and in rare cases day) form, e.g. 2009 September-2010 February, or 1980s, or if using “circa” to indicate uncertainty about dates, e.g. circa 2000-2010. This field is not used if the single date or date range is a simple YYYY or YYYY-YYYY format. If two dates exist for a collection separate with a comma or semi-colon and then fill in the inclusive dates - example 1965; 2009.

         Examples

:

• • 1903, 1950-1955

  • circa 1975 August

  • before 1920
  • after 1920
  • 2015 Fall
  • 2009 April 5 - 2010 May 1
