I have one of the same books from which the pages were scanned in 
front of me.  It is from the John Rylands University of Manchester 
library.  Published by the Chetham Society in 1860, it is  limited in 
its appeal to historians and genealogists.  As the libraries from 
which the dodgy images were scanned are in the USA (Harvard and 
California) and as the Google blurb says that they are scanning books, 
I see no reason for any intermediate imaging.   DPScan works fine with 
images from books in the Bodlean Library Oxford.

They most certainly are.  You could never get near that resolution 
from ink on paper in 1860.
