As the centennial of the Nineteenth Amendment approaches in 2020, the USD Libraries have collected a variety of resources relating to woman suffrage - nationally and in regard to South Dakota, whose male citizens voted to enfranchise women in 1918. This LibGuide is not an exhaustive collection of research but rather various research tools to help students and academics to conduct research on a variety of woman suffrage related topics.
