Case binding is a method of bookbinding that involves attaching a book's pages to a rigid cover. This process typically includes sewing the pages together and then gluing them to a hard cover made of cardboard or similar materials. The cover is often wrapped in cloth, leather, or paper, providing durability and protection for the book. This binding technique is commonly used for hardcover books, making them more resilient than other types of bindings, such as paperback. Case binding allows for a professional finish, making it a popular choice for publishing both fiction and non-fiction works.
