I have a need to cite creators who have different roles for the same source, but I cannot see an example. My specific case involves an author and a separate translator, both of whom I wish to cite as they both contribute to the work being analysed, but I'll try to keep the question general.
My issue is with the punctuation. The role is normally separated from the creator name with a comma, but commas might also be used when there are multiple authors. Hence, how do form an unambiguous list of creators that may have differing roles?
