Well, I don't mind contributing one of my own to this survey. It's from a book review published over 20 years ago when I was nastier than my present mellow self: At the end of the review I remarked that "...one can only read with dismay the statement on the reverse of the title page: 'Clothbound editions of Princeton University Press books are printed on acid-free paper, and binding materials are chosen for strength and durability.'"
