Blueprints are separately catalogued as detail drawings, 1908-1910 (accession number 1991/146); furniture blueprints (Series 839); and landscape plan (Series 838). One archives box (0.2 c.f.) of miscellaneous blueprints have been separated from Series 833 and added to the Detail drawings. The Archives also holds a microfilm copy of the drawings which are part of the Post Papers at the New York Historical Society (Series 840).
