Should these two be combined?

[Misfit]

To the best of my understanding these two books are the same, only a new title with a new publisher. I don't know if any of the second version has been revised and/or rewritten,

If it is just being re-titled when it's being republished, then you would combine them (even if it has minor editing changes.)

But I'd recommend finding a source to cite for that - I checked WorldCat, Library of Congress and Google Books and none linked the two titles together at all.

According to her website entry about Vengeance is Mine, The Boleyn Wife is "a new, expanded edition"...I would guess that would mean they should not be combined.

Edit: I'd put a librarian note to that effect if that's what you decide and why.

Unless the content is new and significant, we usually combine books in which the majority of the text is the same (abridged and unabridged versions of books together, for example.)

In this case, I'd combine them.
