For those interested in Civil War, the Cambridge Room has the eight volume set of the series, Massachusetts Soldiers, Sailors, and Marines in the Civil War, published in 1933. Each veteran is recorded by his military unit, including the Massachusetts Soldiers and Officers in the United States Colored Troops.
