If it is on cotton bond paper then handling it bare handed with clean hands does it no harm.
My wife's family has a lead extrusion tool for stained glass from the 1600's and it has the book that came with it as an instruction manual. It looks like it is on new paper despite the fact that it's over 400 years old.
Can't say what kind of paper, but irrespective of that, I can't say I've seen anyone handle 600 year old books with bare hands and as roughly as this guy was.
