The more I think about it, the more I think the behavior that would work best for me doesn't make sense for the program. What I'd like is for an auto-merge to occur where there's no duplicate format, but for a new/duplicate book entry to be created where there is a duplicate format.

Then, in a separate process (e.g. when I went to read the title in question), I could review duplicate entries to determine whether they're different editions or the same thing. If they're the same, I could delete one of them. If they're different, I could manually update the metadata accordingly. This seems like inconsistent behavior in a way, though. If you use the automerge feature at all, you can end up with different editions in the same book entry if the different editions happened to be in different formats.
