They are going to need a bull too if they intend to make their own vellum! They would also require a good source of freshwater (ie a river) to fill and wash out the tanning pits for steeping the calf hides (& cow hides for the leather bindings). The cow- and calf-bones would then be turned into bone pins, bone combs, and other bone objects, and perhaps hooves into glue.
