direction line
The line of printed characters in a publication
when the abbreviated title of the book, i.e., the
DESIGNATION MARK ,
follows the signature mark, or letter, printed at
the foot of the first page of each sheet. It is
intended to serve as a guide to the binder when
gathering. Until the end of the 18th century the
direction line, printed below the text of the
page, and often between the text and the
footnotes, contained theCATCHWORD ,
signature, press figures, and occasionally the
volume number or part number. See also: SIGNATURE AND CATCHWORD
