DISCUSSION and GUIDELINES

Form and syntax
Follow the applicable rules for display dates in CREATION - CREATION DATE.

If a work has had mutliple object/work types over time, this date is useful in establishing when the work served a particular function or purpose.

Dates may be estimated or approximate; for example, it may only be known that a work was a certain size in the 18th century, but not precisely on which day or year the measurement was taken. For further discussion of dates in general, see CREATION - DATE.

TERMINOLOGY/FORMAT

Free-text: This is not a controlled field. Maintain consistent capitalization, punctuation, and syntax where possible. Index the dates in the controlled EARLIEST DATE and LATEST DATE subcategories.
