"The new book – Suffrage: Women’s Long Battle for the Vote – is the first comprehensive, evidence-based history of the American suffrage movement to appear since 1959. That book [Century of Struggle] was written by Eleanor Flexner...Since Flexner wrote her superb book–on which I and virtually every other suffrage historian has relied–there has been tremendous amounts of new research that has enhanced our picture of the suffrage movement, or I might say, suffrage movements, particularly on the activism of African-American women, who were segregated out of the white-dominated movement in the late 19th and early 20th century."
