Query: Fact checking?

I'm pretty disappointed by this book - as other reviewers have said, there are many interesting facts, but it's quite incoherent. And then I start wondering how many are facts. On p.29 of my paperback edition, we learn that Charles II hid in an oak after the battle of Northampton, and then on p. 101 that someone used spectacles for short sightedness for magnifying small objects. This sort of thing is so lazy and sloppy.
