Jacket

 

a covering, usually removable, of a book or booklet in the form of a sheet with flaps. It is generally made of heavy paper coated for purposes of reinforcement or covered with a transparent synthetic film that also improves the jacket’s appearance. Jackets are sometimes made from polymer films. Originally, jackets were used to protect the bindings of expensive editions from damage; they were later used for purposes of publicity as well. The jacket sometimes serves a purely aesthetic purpose.
