A hardcover is a type of book binding that features a rigid cover, typically made from cardboard or similar materials. This cover is often wrapped in cloth, paper, or leather, providing durability and protection for the pages inside. Hardcovers are commonly used for novels, textbooks, and reference books, making them a popular choice for both collectors and readers. Hardcover books usually have a sewn or glued spine, which helps them maintain their shape and withstand wear over time. They often come with a dust jacket, which is a printed paper cover that adds visual appeal and additional information about the book. Many readers prefer hardcovers for their longevity and aesthetic value in a bookshelf.
