Julie Moore asked on Autocat RDA:

>required?
Field 264 1, if known, is the only core one; 264 2 or 3 become core
only in the absence of data in 264 1.
We consider 264 0 needed, just as we provided that data in 260 contra
AACR2.
We supply 264 2 for electronic aggregators, with the original print
publisher in 264 1. We only supply 264 4 if the year differs from
that in 264 1' it is not core.
