Book and Paper Group Wiki > Book Conservation Wiki > Board Attachment

This page describes the various methods of securing book boards to a text block. Boards can be attached individually to each side of the text block, or they can be attached to an outer covering first, with this unit then attached to the textblock. In general, boards are either sewn, laced, or glued on, and often a combination of these techniques is used.

These methods describe the new binding of books. For a discussion of treatment techniques for reattaching detached boards, see Board Reattachment.

Sewn Boards

The same sewing thread used for leaf attachment (rather than any additional sewing support) is used to attach boards. Examples of this structure include historical Ethiopian bindings and Gary Frost's "sewn board" binding.

Laced Supports

In a supported sewing system, the supports extend beyond the textblock spine and are used to secure the boards. Common supports are cords , thongs, and tapes. These extended supports are fed through pre-made holes, and grooves or channels may also be cut to recess the supports, which are then secured in placed or “fixed” with paste or animal glue, creating a combination of mechanical and adhesive board attachments. Extensions of sewn endband cores can also be used as additional attachments.

Laced Limp Case

In a laced limp case system, a pre-formed covering piece (generally paper or parchment) is attached to the textblock using extended sewing supports which are laced through pre-formed holes. The system still called limp or semi-limp when floating (non-adhered) boards are used.

• 

  Split alum-tawed thongs used as sewing and endband supports are laced through holes in the limp vellum case

• 

  Inside the case, the laced ends of the supports are captured behind extra long head and tail turn-ins. Such bindings may or may not include additional pastedowns.

Adhered Boards

Boards are adhered directly to the textblock before covering, often utilizing extended spine linings, sewing supports, cloth hinges, or endpaper "waste" leaves as additional board attachment. Many variations in materials and construction are possible—the defining characteristic is an in-boards binding that does not include laced supports.

Split Boards

Extended sewing supports or spine linings are adhered between the two layers of a single board which has either been split (delaminated) or made up in multiple layers.

Case Binding

In case bindings, both boards are brought together in a single complete covering piece, called a case, which is attached to the bookblock as a final production step.
