Case Binding is Used for Hard Cover Books

Case or edition binding, the most common type of binding for hardcover books, involves sewing the individual signatures together, flattening the spine, applying endsheets and a strip of cloth to the spine. The hard covers are then attached. The spine of a case bound hard cover book is typically rounded and there are hinges (grooves) along the edges of the cover near the spine. Case bound books often also have dust covers or jackets.
