panel spine linings (Q456): Difference between revisions

A square or rectangular lining which more or less exactly covers the spine between the joints and two adjacent sewing supports. In the panels at head and tail, the panel linings extend to the end of the spine, though in some sixteenth-century bindings, the panel linings at head and tail were divided into two to expose the change-over station, perhaps with the intention of disguising the bump created by the kettlestitches.
