openability
That characteristic of a bound book which allows
the leaves to lie relatively flat when the book is
open, with no weight or pressure applied
(especially along the binding edge). Openability
depends to a certain degree on the size of the
book, and to a considerable degree on the weight
and thickness of the paper, its grain direction in
the book (which should be parallel to the spine),
the method of sewing, and the overall quality and
structure of the binding. Cf: LYING FLAT .
