A book cover is the outer protective layer of a book, designed to attract readers and provide information about the content inside. It usually features artwork, the title, and the author's name. A well-designed cover can spark curiosity and encourage people to pick up the book, making it an essential part of the publishing process. There are two main types of book covers: hardcover and paperback. Hardcover books have a stiff, protective cover, while paperback books are more flexible and lightweight. Both types serve the same purpose but appeal to different audiences and preferences, influencing how readers choose their next read.
