How to Find Out the Market Value of Art Works and Collectibles

As a public institution, the New York Public Library's Art and Architecture department cannot engage in questions about valuation, attribution or authentication, nor recommend individual appraisers for works of art. Our department does have a reference collection of sales and auction catalog indexes and price guides for collectible items. These resources are available for use in the department, but the staff cannot answer queries from these publications over the telephone or by mail.
