"case binding"的定义和意义

What is "case binding"?

Case binding is a bookbinding method where the book's pages are sewn or glued together to form a text block, which is then encased in a hard cover. The cover, often made from cardboard covered with paper, cloth, or leather, is glued to the text block along the spine. This type of binding is common for hardcover books and provides a durable and protective exterior, allowing the book to withstand regular use while offering a professional appearance. Case binding is known for its strength and is used for a wide range of book genres, from novels to reference works.
