Garver here. 
That's right. Blame it all on the bindery!
What a shockingly cheap and startlingly effective way to get all the folks who have invested so heavily in the purchase of your book to actually look at it carefully, and not just skim through it lightly before placing it prominently on the coffee table as a silent symbol of sophistication!
Classy, and a lot cheaper but just as effective as sending out a note saying, "Please examine your books carefully as I had a $100 bill bound into one of them--but just one of them."
All best, (And, as previously noted, I have waded through the thing, from one end to the other, and did so without provocation or bribery. In so doing, I can honestly say, as an unsolicited testimonial, that, "Even though it will absorb some of those minutes God allocated to you at birth, looking and reading, even looking and reading this book, should generally be regarded as one of life's more beneficial activities!"
