leather hinges ( leather joints )
Endpaper hinges made of leather and designed to
add strength at the point where the endpaper
flexes. They are used with simple folded endpapers
in either of two ways—by sewing them in with
the endpapers while the book is being sewn, or by
pasting them down on top of the endpapers after
covering. Leather hinges (or joints) have been
used since the 17th century in Europe, and between
1750 and 1800 they were a fairly common feature of
the best English morocco and Russia bindings. They
were usually heavily embellished with fillets,
rolls, and small tools. (83 , 236 , 335 )
