The library was built for the needs of the local population in 1903. It is located on the corner of Library and South Main Streets, across the tracks from the museum. It was built with a $15,000 grant from the Andrew Carnegie Foundation and matched with $10,000 raised from the citizens of Pittsfield, and $5,000 from the estate of the late Robert Dodson. The library and monument to the soldiers of the Civil War, which is in front of the library, were dedicated in 1904 and named to the National Register of Historic Places in 1983, the same year the interior of the dome was painted. Granite inscriptions of World War I veterans are mounted on each side of the front entrance doors. The small masonry building and the land on which it sits is owned by the Town.
