Dust jacket
From Wikipedia, the free encyclopedia
The dust jacket (sometimes dust wrapper or dust cover) of a book is the usually detachable cover, often illustrated, consisting folded, front and back flaps, by which the cover attaches itself to the front and back book covers. These are thought of as having the purpose of protecting the binding of the book from scratches. However, they are often quite fragile, and since dust jackets have intrinsic value, aesthetic and financial, they themselves are wrapped, by bookman, and bibliophiles, for example, in transparent, acetate book jacket covers. In the world of book collecting the presence or absence of an original dust jacket has a significant impact on a collectible book's value. Often the front flap has information about the story, and the back flap tells about the author.
In schools, teachers often require students to use a book cover to protect textbooks. Made of paper, fabric, or plastic, these function like a dust jacket to protect the front and back cover from damage.
