In 2015, Hagley acquired the Rothschild Patent Model Collection of 4101 models. This makes Hagley's collection (now numbering 4971) second only to the Smithsonian in holdings of patent models. 100 selected models will be on display in the Copeland Room of the Hagley Library during Library hours. Also open the second Saturday of each month. This is not part of the regular Hagley Museum admission. Use Buck Road entrance.
