spine lining
1. The process of reinforcing the spine of a sewn
book, after gluing-up, rounding and backing, and
before covering or casing-in. The spine lining
material (which is usually a fabric) does not
generally extend closer than within 1/8 inch of
the head and tail of the text block. In edition
and library binding, the lining material, or
initial liner, if there is more than one, extends
beyond the edges of the spine, and is attached to
the boards of the case; any subsequent lining,
however, stops at the shoulders of the spine.
The purpose of lining the spine is to support it
and to impart a certain degree of rigidity, while
still maintaining the necessary flexibility for
proper opening; consequently the weight and
stiffness of the spine lining material is of
considerable importance. See also: SPINE LINING FABRIC

PAPER . 2. A term used incorrectly with
reference to the strengthening or stiffening of
the area between the boards of the covering
material of case bindings. This lining is more
appropriately called the INLAY (1) .
