This society is dedicated to preserving artifacts and memories from the steamship days of yore. Its members promote conservation and preservation efforts, maintain a library, create exhibits and publish a quarterly journal. The collection contains approximately 200,000 photographs of cargo vessels, cruise ships, lake and coastal ships, military transports, passenger liners, river steam boats, tugboats and work boats. There are also 25,000 postcards, brochures and other items devoted exclusively to the history of engine-powered vessels. Visitors are requested to make an appointment.
