Alternative Dates

When providing alternative dates in an access point, follow RDA and record both years in full. In the 046, record the years in square brackets separated by a comma, following EDTF standards (detailed instructions are available in DCM Z1 046).

Note: Alternative dates are meant to represent two consecutive years. Do not use this construction for non-consecutive years.
