About the Exhibit

Exhibit Summary and Site Map

Systems at Work looks at America’s postal system in different ways. You can click on a selection of years used to showcase how mail was moved during each of the time periods. The year sections also provide information about aspects of postal operations from that era. A series of “Catalysts of Change” moments provide information about items or methods that helped change the way the system operates. Objects scattered through the exhibit help showcase eras and operations.
