This book came in with several deterioration issues including pages that were very brittle and stitching that was failing. Also, the cover boards were lost and the leather spine was gone.
For this rather substantial volume it was necessary to de-acidify every page. Restoration of the spine was also an intensive process as it involved a series: fabricating new archival parts, glueing, and pressing under blotters. Fortunately, once it was done, we were very happy with the strength and appearance, the former giving it a condition that will allow it to be opened by grandparent hands and little grandkid hands for years and years to come.
