blankbook binding

A style of binding for books meant to be written in and which, therefore, must lie flat at any place the book is open. Blankbook binding is one of the principal subdivisions ofSTATIONERY BINDING and differs greatly from the other major nit of binding, LETTERPRESS BINDING . One of the major differences is that blankbooks, or account books, as they are also called, are rounded but not backed, having instead a SPRING-BACK , which, in conjunction with the LEVERS , causes the spine of the book to "spring" up when the book is opened, thus giving full access to the gutter of the opposing pages. The best blankbook binding is very durable, with sewing on wide bands of webbing, rather than tapes, the ends of which are secured between split boards. The books also have heavy linings and strongly reinforced endpapers, called "joints" in a blankbook. In addition, it is not unusual for the folios to be sewn first to heavy cloth guards before being sewn to the webbings. Additional strength is sometimes imparted by hubs on the spine (which also protect the lettering) and bands either over or blankbook frame under the covering material. Although formerly always covered in leather, many blankbooks are now covered in heavy duck or canvas. Called "account-book binding" in Great Britain. (58 , 320 , 339 , 343 )
