The monograph surveys the expansion and varieties of higher education available to women in the United States, distinguishing broadly between liberal college training and professional or vocational instruction. It categorizes institutions as coeducational colleges, independent women’s colleges, and women’s colleges affiliated with men's institutions, and examines regional patterns in coeducation. The analysis links western prevalence of mixed education to public-school traditions and to the prominence of women as teachers following the Civil War, while eastern developments followed a different private-college trajectory. The work reviews early institutional examples, traces the spread of state universities admitting women, and presents comparative data on women’s participation across disciplines and time.
