scaleboard ( scabbard )
The thin wooden boards, which are only slightly
thicker than modern pasteboard, made of oak,
maple, or birch wood, and used by bookbinders in
Colonial America in lieu of paper boards,
principally because of their availability and ease
of use. It was used, even after paper became
generally available, for the cheaper sort of work
well into the 19th century. Scaleboard is not to
be compared with the pasteboard of earlier times,
which was sometimes very thick. (115 , 200 )
