This subseries houses journals that list works of art sent out to clients "on approval" for sale and items received by the firm "on approval" for purchase. Information includes names of clients, such as museums, galleries, dealers, and individuals, titles of artwork or decorative art objects, and stock inventory numbers. Entries also indicate whether the piece was sold or returned, along with date of sale or return. Several of the journals also include name indexes in the front. Black entries appear to indicate items the firm sent out to clients for approval; red entries indicate items the firm received on approval. The last journal in the subseries exclusively lists "on approvals" for Paris and Geneva, 1926-1939 (Jacques Seligmann & Fils, Paris, and Jacques Seligmann & Co., Inc., Geneva).

Although the journals are arranged in chronological order, many contain scattered dated entries that do not match the chronological bulk dates of the journal; it is unclear why these entries appear out of order in many of the journals. It should also be noted that there is an overlap of years in the journals dated 1921-1927 and 1922-1928.
