sawing in
The process of sawing grooves across the spine of
the gathered sections of a book for reception of
the cords used in sewing a book on recessed
(sawn-in) cords. "Sawing-in" was introduced as
part of the search for economical binding
processes which began as early as the 16th
century. Centuries later, in combination with the
HOLLOW BACK , it
was to have a significant effect on the future of
craft binding. See also:RECESSED-CORD SEWING .
