RobertHello Annette,Here are the PCC Guidelines for the Application of Relationship Designators in Bibliographic Records:
"Include a relationship designator for all creators, whether they are coded MARC 1XX or MARC 7XX. If the MARC 1XX is not a creator, the addition of a relationship designator is optional though strongly encouraged. Add a relationship designator even if the MARC field definition already implies a relationship. Relationships should be coded explicitly and not inferred from MARC or other parts of the record.Guideline 9. PCC highly encourages including relationship designators for all access points whenever it is clear what the relationship is."

We are implementing RDA original cataloguing soon and I would like to know whether the usage of relator codes (#e) with authors, editors, corporate bodies, etc. is mandatory in RDA? We feel that it is sometimes superfluous (like #eauthor) but would not like to contravene mandatory RDA guidelines. If it is mandatory, could I please have a reference to present to my "critical" colleagues. I have been unsuccessful in finding a clear guideline thus far.
Thank you and kind regards.
