The only hint in the book itself that it's not the right printing is the note on the blank pages 6 and 7 "[[CP: Other permissions to be listed here, when all in. Allow 2 pages]]". That and the fact that, two weeks into my class, we figured out that all my page numbers are at least 20 pages off, and I'm missing the timelines, and ALL THE ILLUSTRATIONS.Other than that, it's a nicely put-together text, and my class is really enjoying it. I'm just disappointed that Amazon sent a non-final copy.
