cover
1. The outer covering of a book placed on a text
block to protect it both in use and storage, and,
in many cases, to serve as a medium of decoration.
A cover may be limp, e.g., a LIMP BINDING , which
has no boards and the covering (usually vellum) is
turned-in on itself and covered with the board
papers; semi-limp (or semi-flexible), in which the
boards are thin and flexible and are covered with
leather or cloth and drummed on. See: DRUMMING ON . 2. A SELF-COVER , as of a
pamphlet; or a stiff cover, e.g., more or less
rigid boards covered with leather, vellum, cloth,
paper, or combination thereof. Stiff covers are
usually glued down all over, turned in and covered
with board papers. In edition and library binding,
the term CASE (1)
is more appropriate. 3. The outside leaf of a
periodical issue. (131 , 236 , 256 )
