Treatment Examples

Conservation of the Nuremberg Chronicle:
An illustrated report

Japanese Paper Reback

This is a relatively recent addition to the repertoire of the book conservator. Using Japanese paper the conservator can repair joints, headcaps and corners with a minimal of amount of effort. The repair is then touched up and refurbished with acrylic paints and an acrylic wax. This is quick and simple, yet aesthetically pleasing, repair that works well on almost all bindings in leather, vellum, cloth or paper.

Full Conservation Treatment

This example shows a full treatment on an 18th century French history of the Catholic Church. There was extreme mold damage to approximately the last 50 pages and the rear board. The leather covering was removed, the boards consolidated and repaired, the paper repaired using a "pulp-fill" technique and Japanese paper. It was then resewn as needed, new endbands sewn, and then recovered with calfskin. Finally, the original covering fragments reapplied.

Vellum Rebacking

This two-volume set of full vellum bindings from the early 19th century had been previously rebacked and was once again, in need of a rebacking. In order to complete the rebacking, the endsheets needed to be lifted, the spine cleaned and lined with linen. The case was reconstructed using new vellum.

Wooden Boards Binding

This early 16th century binding, while in essentially very good condition had a cracked front cover, weakened paper inner joints and was missing its clasps. The clasps on many bindings of this type are often missing or damaged because they were either removed over the course of time or because they simply wore out. In this instance, the front endsheet was carefully lifted, and the board partially drilled. A dowel was then inserted and sanded down till it was flush with the board. The endsheet was lined with Japanese paper because of other damage, and reapplied. At this time the joints were also repaired. New clasps, based on an impression/shadow of the original, were made of brass stock in a manner compatible with what might have been there.
