The Andover Historical Society seeks to preserve and share the history of Andover, Massachusetts, founded 1646. To this end, the society operates the 1819 Amos Blanchard House and Barn Museum which illustrates the life of an early 19th-century (1820-1850), middle-class family. The barn contains a variety of vernacular tools. According to the society site, tour topics include "politics, religion, women's roles, economics, banking, youth, education, household management, and agriculture." Extensive archival materials are available for research at the Caroline M. Underhill Research Center.

The society offers exhibits, period rooms, guided tours, educational programs, hands-on activities, and archival access.
