RDA 1.3 (for the core elements) - include the elements only if they "are applicable and readily ascertainable."
For these publisher-related elements though RDA does indicate the use of the "... not identified" placeholders. These signal at a minimum that the resource can be determined as being published but the place and name of publisher cannot be determined. The distribution and manufacturing data is triggered as core in the absence of identified publisher information, so that at least some useful identifying information must be recorded if applicable and readily ascertainable for published resources. New to RDA is the split of the AACR2's date of manufacture into two elements. The date of manufacture of an unpublished (i.e. one-of-a-kind, not distributed, etc.) resource is now Date of Production. Two new elements responding to archives and museum needs have been added to the Production Statement and these are: Place of Production and Producer's Name (these are not core elements). AACR2 1.4C8 and 1.4D8 prohibited recording the place and name of a producer for unpublished resources, and recycled the date of manufacture as the date for the production of an unpublished resource. RDA takes AACR2's division of published vs unpublished resources and crafts a new element, Production Statement, out of that.

It seems that the rules and the PCC policy statements are quiet on this possibility. Seth Huber University Library Specialist Western Carolina University
