A book cover is the outer protective layer of a book, designed to attract readers and provide information about the content inside. It typically includes the title, author’s name, and artwork or images that reflect the book's theme. Covers can be hardback or paperback, with various finishes like matte or glossy. Book covers serve both functional and aesthetic purposes. They protect the pages from damage and dirt while also enticing potential readers. The design can influence a reader's first impression and often plays a significant role in a book's marketing and sales success, making it an essential aspect of publishing.
