If only the spine changes, is it an ACE situation?

[Alison]

The first printing had a blank spine, which was quickly corrected in a second printing to show the title. The rest of the cover (i.e., what's shown on GR) is identical and the ISBN is the same. Is this an alternate-cover edition situation? Or is it not enough of a change to note?

[Scott]

What would be the point? You can't see the spine here.

[Emy]

To expand on Scott's comments - we don't usually show the spines of covers, so there wouldn't be a need for any type of alternate cover as far as I can tell.
