Goodreads Librarians Group discussion

I've run across a couple of instances of this recently and I'm not sure what the policy should be.

One example is Anathem

Apparently Neal Stephenson is not only the author, but is also credited as one of the Narrators of the audio book.

How do we handle this? I don't want to tag the author as Narrator, since he is still the author. I haven't tried listing his name twice, and I'm guessing we may not want to do that even if it is possible.

Why not? Makes sense to me to list him again with "narrator" as the role.

The system gets screwy when an author is listed twice. However, you can make his role author/narrator.
