Yellowskin

Yellowskin or Year-book of Tuckborough was one of the oldest Hobbit chronicle books said to contain entries dating back some 900 years before the War of the Ring.

It contained chronicles of the Took family, including marriages, births and deaths, but also legal details and references to important events in the Shire as a whole. Yellowskin became a source for much of the historical information, especially about the Tooks, to find its way into the Red Book of Westmarch.

Etymology

The name 'Yellowskin' presumably derives from the aged and decayed condition of the book, suggesting that the records of the Tooks were recorded on vellum, or some other form of parchment made from skin.
