Hardcover books, also known as hardback books, are bound with a rigid protective cover, typically made of cardboard or thick paper. This sturdy construction helps to protect the pages inside and gives the book a more durable feel. Hardcover books often feature a dust jacket, which is a printed paper cover that wraps around the hard cover, providing additional design and information about the book. These books are commonly used for novels, textbooks, and reference materials due to their longevity and ability to withstand wear and tear. While they tend to be more expensive than paperback books, many readers prefer them for their aesthetic appeal and the quality of the reading experience they provide.
