Connoisseurship. We strive to provide our clients with the best possible examples of the most important items in top condition and the most desirable state. For every great first edition or important photograph we handle, there are thousands we reject on the basis of quality, condition, priority, and historical significance. Every day we consult with our clients concerning the fine points distinguishing the ordinary object from the extraordinary treasure.

Bibliographical Research. Thorough bibliographical research and accurate cataloguing are hallmarks of our business. We maintain a reference library of more than 10,000 volumes, including bibliographies, dealer, auction, and exhibition catalogues, and more than a century of auction records and price indexes. While most dealers and collectors are limited to online price data, our clients benefit from our use of more than 100 years of auction records.

Auction representation. We regularly represent clients at auction, providing expert independent analysis of bibliographical points and condition, the market, strategy, and saleroom bidding.
