The mission of HSWC is to stimulate interest of present and future generations in the history of Windham County, Vermont, and its several townships, and to acquire a more intimate knowledge of the methods, customs, hardships, and triumphs of its present ancestry. HSWC achieves it mission through two museums, The County Museum and the West River Railroad Museum, which are open to the public without charge, and where exhibits and resources share the history of Windham County, Vermont with people of all ages from near and far. The Society also houses and maintains collections relating to Windham County and makes them available for exhibits, programs, research and geneology services. It publishes a newsletter for members three times each year and offers events and educational programs that relate to its mission. It also sells mission-related items for sale at mini-stores.
