Goodreads Librarians Group discussion

I'm trying to add a book that is an anthology. As you may know, there is usually an editor listed as the primary author (usually they are listed on the cover as "Edited by X").
But when it comes to editors who ALSO contributed with one work included in the anthology, how should their roles be listed on the Goodreads record?
I'm thinking of some options:
1- Listing "X (editor and contributor)" [listed as primary author]}
2- Listing "X" [primary author with no role]
3- Listing "X (editor)", then the authors including "X" again at the end of the list (the story of this author is the last one in the book)

Let me know what you think!

Since we list the authors as contributors, I would add it as "Editor/Contributor."
