“This notebook was owned by the 19th Century poet, preacher, and naturalist, George Crabbe. The binding was damaged, and split along the joint, and some of the sections were loose. However, of most concern were the loose plant and insect specimens that were pressed between the pages.”
Read more about how it was repaired and restored at NLS Conservation: 19th Century Naturalist Notebook with Specimens. The rest of the blog also has some interesting photos of old bindings being repaired.There are only a few posts, all dated 2011. I wish they’d kept up the blogging!
