Barlow, Frank, et al., ENGLISH MONARCHS, Berkeley: University of California Press, 1970. Beautiful ¼ maroon and mauve cloth hardcovers, w/gilt titling and gilt-stamped lion to lower front board, 1970 reprint of 1964 1st eds., 7vols complete, 8vo (9.1875x6.0625”), Very Good+/n.a., approx. 2,600 pp. Only flaw noted is a stain to the top edge of vol.2, external only.  
The book is praised for its formidable scholarship, with The Spectator noting Barlow “recovered the real Edward” and The Times calling it “an intellectual exercise of the highest order.” Reviewers appreciate its scholarly and factual focus but hint at its being a bit much for casual readers. 
Quite the distinctive set of books indeed – and a treasure house of knowledge regarding English Monarchs.
