Something on the Origins of the Two Largest Map Collections in the USA and the Practice of Map History
/1 June 2025: I have included almost the entire post, with few changes, in my forthcoming monograph, Comparative Map History and “the History of Cartography”, section 3. That publication is the copy of record, as it were, so I have deleted the post from this blog. For information please refer to the monograph (ordering information etc. at right).
