Dust jacket

A dust jacket is a removable paper cover that wraps around a hardcover book. It usually features the book’s title, author, cover art, and promotional blurbs. Its primary purposes are to protect the book’s binding from dirt and damage and to provide marketing information. Besides practical protection, it often enhances the book's visual appeal and collectible value. Dust jackets are typically discarded after purchase but can be preserved as part of a collection. They are an important part of a book's presentation, especially for new or special editions.
