Dacier did not examine all the art works in person. When he questioned the attribution of an original work he placed an asterisk (*) next to the relevant catalogue number, this was when a work had been previously catalogued as by Saint-Aubin but Dacier doubted the attribution. (For his explanation of this system, see v.2, p. vii). Therefore caution must be exercised when his catalogue numbers are given as pedigree for Saint-Aubin works. The Bibliothèque nationale in Paris owns Dacier's personal copy of his catalogue, which he continued to update and annotate until shortly before his death. An American scholar, Kim de Beaumont, transcribed these annotations. A copy of her transcriptions is in the Frick Art Reference Library in New York.
