Use in Book Manufacture (History and Techniques)

Covering Material

There are differences of opinion in how to describe various styles of parchment-covered bookbindings. Etherington & Roberts (1982), Ligatus, and Albritton and Amato (2016) describe a "limp binding" or "limp covers" as having no underlying board. Although Ligatus disagrees with the use of the term, but both Ligatus and Albritton & Amato agree that a semi-limp binding has a thin, flexible board underneath the covering material. Stiff-board bindings have rigid boards that are fully adhered, drummed-on, or loose (i.e. the classification depends on the rigidity of the underlying material).

Other conservators base the classification on whether or not the covering material is adhered to the board. If there is no adhesive connection, then it is a limp binding, and if there is an adhesive connection, it is a stiff board binding [citation needed].

Semi-Limp Vellum

Albritton and Amato (2016) describe two types of semi-limp bindings:

• a wrapped board binding has a "full flexible stiffener found wrapped beneath its outer parchment cover."
• a floating boards binding has "two separate flexible boards inserted at the front and back covers."

Stiff Board Vellum

As discussed above, this can refer to a binding with a stiff board underneath the vellum cover or to a binding where the vellum is adhered to a board, rigid or not.
