This pair of elephant folios were printed in 1723 and are in a fine early nineteenth century gilt calf binding. As is not unusual with books of this size and weight, the joints had failed and the boards were detached from the text block of each volume. The block had been sewn on recessed cords and the spine leather had been mounted on a hollow, this had come away taking the leather with it and some pieces of leather. The sewing was otherwise intact.
As the books had sturdy text blocks and the boards were dense and heavy, I decided that the best approach for reattaching the boards was board tacketing. After the boards were reattached, the spine of each volume was cleaned off, given a new hollow and rebacked in hand-dyed calf. After consolidating the powdery leather with Klucel G, the original spine leather was reattached.
