Bradel binding
A type of binding having a hollow back, and not
unlike a library binding, except that it is
considered to be temporary. The style was
originated in Germany by Alexis Pierre Bradel,
also known as Bradel l'ainé, and also as
Bradel-Derome, son-in-law and successor to
Nicholas-Denis Derôme. The style was taken
to France sometime between 1772 and 1809. Bradel
bindings generally have split boards into which
are attached the extensions of the spine lining
cloth. The edges are uncut, sometimes with the
head edge being gilt. They generally have a
leather or linen spine. In France the style was
known as "Cartonnage à la Bradel," or as
"en gist." See also: LESNÉ,
