Lamy of Santa Fe: His Life and Times

US-only true first: Farrar, Straus and Giroux, New York, 1975 (Pulitzer Prize for History, 1976); no contemporaneous UK edition traced in the sources consulted. The census note misses a real precedence point that is corrected here: the 1975 first edition was issued in two forms, which is why dealers catalogue the black-cloth issue specifically as the "first trade edition". A signed, numbered large-paper limited issue was published alongside it, in a slipcase and without a jacket as issued. Name both: the signed large-paper limited issue and the black-cloth trade issue. The limitation figure is not settled in the sources consulted -- one dealer describes it as one of 500 large-paper copies while numbering a copy "#63 of 490" -- so the figure should be read off the limitation leaf of the copy in hand rather than assumed. "First thus" trap: the FSG/Noonday trade paperback (ISBN 0-374-51588-3).
