The Rosenbach staff welcome your questions about our collection and about your books, manuscripts, and works of art. Please fill out the form below to submit a reference question through the web. Before contacting us, however, you may find it helpful to look at some of the general information in our Collections FAQ about old & rare books; appraising, authenticating, and selling materials; and caring for your collection. Otherwise, if you are looking to visit our reading room to do research please make an appointment here.
