Our Heroine is reading something, about 100 years old, in whatever would be the closest functional equivalent to a cheap notebook--something that someone might write unofficial or low-priority notes/records in.
first question: am I correct in assuming that this would most likely be either a leather folio with loose pages, or a somewhat crudely bound book, made of relatively low grade/second rate parchment?
second question: assuming it has been stored reasonably well (though not hermetically or anything), and not handled excessively, what kind of *condition* would it be in?
Searches tried so far: (parchment OR vellum) (storage OR deterioration OR decay)--I mostly found stuff about either poorly stored parchment (damp conditions and such), or chemical decay from either treatments to make a book pretty, or pollution. Neither apply here.
(as a side note I can probably figure out on my own if I poke my brain hard enough... assuming Our Heroine's 14, and the writer of the 100-year-old notebook was an adult ancestor, how many "greats" would he probably be? Usual marriage age in the culture is 16-20)
