buckle
1. The wrinkling near the head and binding edge of
a section, which may be caused by paper that is
too thick, or by too many folds in forming the
section, and which may be accentuated by the grain
direction of the paper being incorrect—i.e..
running from spine to fore edge rather than head
to tail. 2. Book covers or cover boards that have
been warped and twisted in several directions. See
