A dust jacket is the protective and often decorative outer covering of a hardcover book. It's also known as a book jacket or dust wrapper. Its main purpose is to shield the book from dust, dirt, and damage. However, it also serves as a marketing tool, featuring the book's title, author, and a blurb designed to attract readers. Think of it as a removable coat for your book. It often includes artwork or designs related to the book's content.
