secondary binding
A second or subsequent binding of a publication.
Although the term may also be applied to hand or
library bindings, it is used principally with
reference to different times of edition binding.
When a publisher does not know how many copies of
an edition will be sold, and does not want to
assume the cost of binding and inventorying copies
which may not sell, he may have copies bound in
segments, and, as this may spread the binding of
the full edition over a period of time, the
different bindings may vary because of changes in
cloth color, spine lettering, etc. The practice of
deferred binding was more prevalent, and the
periods of time much longer, in the 19th century
than today, as edition binding is now very highly
mechanized and standardized. A REMAINDER BINDING is
not a secondary binding. (69 , 140 )
