Thanks, Alan. That covers exactly what I want to know. I may not agree with the treatment in RDA (I didn't agree with it in AACR2, being based on a narrow view of editorial roles) but as long as I understand it and can explain it to students that's all that really concerns me.

However, someone who is described as an editor in the SOR , may be deemed to be an author if the extent of their revision or adaptation is judged to result in the creation of a new work. This is a question of judgment and will depend on the evidence in the resource itself or obtained by comparing both resources. Pragmatically we will consider new editions to be new expresssions rather than new works unless there. is compelling evidence to the contrary. See also 22.214.171.124 Editor of compilation The relationship designator "editor of compilation " also denotes a relationship to an expression, not a work. This would be used for someone who has contributed to an aggregate work, such as anthology. If the anthology consists of the works of a single person, family, or corporate body, that person would be the creator and the preferred title for the work would be either a conventional collective title or an established title. The authorised access point for the work, would be contructed from the name of the creator followed by the preferred title for the work -. 126.96.36.199,/188.8.131.52 If the anthology includes works of more than one person, family, or corporate body.
