A wrapper originally used to protect the covering
material of the book from soiling or other damage,
but now also used for promotional purposes. It may
be plain, printed, or illustrated, and is flush
with the covers of the book at head and tail, but
folded over the fore edge of both covers. It is
usually detachable. Modern book jackets are often
very elaborately designed and are frequently
printed in color. The book jacket, in one form or
another, can be traced back to the 16th century.
Also called "book wrapper," "dust cover," "dust
jacket," "dust wrapper," "jacket," and "wrapper."
