Scope note:

Date range including earliest and latest dates of items in a group. For example, dates for the subjects contained in the archival materials, used particularly when the subjects do not correspond to the dates when the group or series was created. For example, a series created in the 1970s about the 1941 attack on Pearl Harbor would have a coverage date of 1941 and inclusive dates of 1970-1979 (e.g., 1941 (coverage), 1970-1979 (inclusive dates)).
