(done) Merge empty duplicates - The Call of Cthulhu and Other Stories

[David]

Of the two redundant editions, one was empty and I merged it with the default (which is an Audible).
The other edition was not an empty edition, it was marked as an Audiobook. I found two other such Audiobook editions, one with ISBN, so I queued the deletion of the redundant two audiobook editions to the ISBN edition.

Done at last
