Combining/Separating Editions

[Donna]

I'm not sure if this is the right place to ask, but I have a question about combining multiple issues of the same book. Should an Annotated, illustrated and "regular" edition of the same title be combined as the same book or should each of those be listed as their own separate editions? Here is an example: Ghost Stories of an Antiquary, Ghost Stories of an Antiquary Illustrated & Ghost Stories of an Antiquary: Annotated all by M.R. James Originally there were some combined and some listed separately on this author's page. I combined them, but then started to wonder if they should be separate or not. Someone please advise. I will be happy to go back and separate the Annotated and/or Illustrated versions if that is the way they should be listed.

Thank you,
~Donna

As long as they have all the same stories, they should be combined.

Thanks Scott. That's what I thought, but I just wanted to make sure.
