Stewf,
Thank you very much for the informative response. I see from your link that De Vinne is indeed available, so I will pursue whether it has much unicode support, and also if it has the ranging numerals that are used in the original.
The Benton Modern link you gave is good too, and more ... modern. It is probably a better bet as I do have a lot stuff in different alphabets to handle, and it comes with a 30-day free trial.
I can't help but be impressed with the overall look of pages from early last century, set in the commonly used fonts. Sheer personal taste, of course.
Russell.
p.s. I should have added that the 1911 book from which I took the scans was printed by the Aberdeen University Press.
