Is there an official way to diffrentiate between the two versions of Mirrocle World?

Gah! I keep forgetting to ask something. This is the last one, I promise. Mods, if there's a way for you guys to paste threads together, please do.

Anyway, is there an official way to differentiate between the two? Or are they both called simply "Mirrorcle World"?

I can't find anything on the covers about it and sites are inconsistent. Some call them "Depend on you ver." vs. "YOU ver.", others "[JACKET A]" vs. "[JACKET C].
