What is a Rev Sub Edition Book?

Well, couldn't find out the section to discuss books. Anyone know what the abbreviation "Rev Sub Edition" Means?

Or point me to the right place to ask this.

The answer may depend on the context in which you saw this phrase, but a websearch for "book sub-edition" finds

From what I can see, it looks like it's a revised, revised edition. A book has been reprinted in a revised form, and then again with further revisions, but not enough changes to justify updating the revision number.
