The problem is the publication place attached to this specific ISBN. The article gives the 2013 revised edition as “Milano: Rizzoli” while also identifying it with ISBN 0-8478-4213-4 (13-digit: 978-0-8478-4213-1).

For that exact ISBN, Rizzoli’s own product page is on Rizzoli New York and lists the book as the 2013 hardcover edition with 396 pages and ISBN 978-0-8478-4213-1. WorldCat likewise catalogs that edition as “Publisher: Rizzoli, New York, 2013.”

So the page count and ISBN match, but the location Milano does not. This looks like a bibliographic mix-up: the 2013 edition identified by this ISBN is the New York Rizzoli edition, not a Milan one.
