These boxes are designed to prevent parchment textblocks or parchment covered books pushing open the box lid, as they would with a conventional drop spine box.
Protecting the volume from physical and light damage, this box design also buffers the contents from the surrounding environment. It gently restrains the movement of the book’s parchment elements, constraining warping and cockling which minimises pigment loss from the illuminations and distortion of the binding.
This highly flexible design means it can provide each volume with the specific care it requires and be adapted to support volumes with other characteristics such as girdles or wedge-shaped textblocks.
