"Without books the development of civilization would have been impossible. They are the engines of change, windows on the world, "Lighthouses" as the poet said "erected in the sea of time." They are companions, teachers,magicians, bankers of the treasures
of the mind, Books are humanity in print."
Since it is a temporary zone, you shouldn't register it with nyisutter. Just make a notation in the comments portion of the release notes that you released the book from your Yard Sale Crossing Zone. I did something similar for Halloween. I made a list of all the books with their BCID numbers and crossed off any that didn't get taken, then released the rest. You can journal them, rather than releasing, if it seems more appropriate to you.
