Just to chime in with support (a) for adding Performer I skimmed through the "roles" explicitly coded in records I have received as part of the LC/Ameritech competition and reckoned that everything else was either included in Rebecca's list or clearly too specialized (e.g. slide-maker, lithographer) (b) concern about Illustrator The definition seems book-centric. Would it include the photographer for a book illustrated by photographs or the "cover" designer for recorded music (even music distributed over the web will have associated graphics as part of its packaging, surely). I would be tempted to drop Illustrator and assume that it is another particularization of Contributor/Collaborator that doesn't belong on the minimalist list.
