After allowing this volume to passively grace my music stand for several years, I decided it would be better appreciated by a pianist friend of mine, and so restored it to a usable state. The textblock was coming loose at the signatures and was almost completely separated from its case. I repaired the signatures, resewed and lined the textblock, then refit the textblock into the original case after lightly treating the spine leather to quell disintegration at the head and heel.
In lieu of my latest restoration project (which should be completed in the next few weeks), I can't help but flaunt the newest (and, ironically, the oldest!) addition to my personal library: a second-edition printing of Samuel Johnson's first dictionary of the English language, published in two volumes in 1756. My copy is volume two, 'L-Z'.
It came to me in a very sorry state: most of the original cover is gone, with only the laced-in back board still attached to the textblock, although the sewing itself is in great shape. I also noticed a tiny knot of red and gold silk threads sticking out of spine edge, which might be a clue as to what the original sewn endbands looked like.
