1. The free end of the cords, thongs, or tapes on
which a book has been sewn, that are used to
attach the boards (or case) to the next block.
Tapes may be glued to the inside surface of the
boards, or they may be glued into boards that have
been split horizontally (or between two boards
glued together); this is "split-board binding,"
that was at one time the traditional method for
library binding. In library binding today, when
tapes are used, the slips are glued to the
overhanging spine lining cloth and both are then
glued to the insides of the boards of the case.

BOARDS . When cords or thongs are used, as in
craft binding, they are strung through holes
punched in the boards, in which case they are said
to be "laced-in." See also: HOLING OUT ; LACING-IN . 2. A term
sometimes applied to the paper forms used in
writing instructions to the binder. 3. Matter not
set up into pages, but pulled as proofs, on long
slips of paper called galley proofs. See also: PROOF (2) . (156 , 236 , 335 )
