Dorr left the "Evening Post" in the summer of 1906 and traveled in Europe, where she became even more interested in the growing international movement to grant the right to vote to women. She continued this activity upon her return to America. Dorr wrote investigative features and gritty vignettes on the grim situation faced by urban working women for the short-lived reform periodical, "Hampton's Broadway Magazine." Much of this journalism was collected in hard covers in 1910 as "What Eight Million Women Want," a book which was regarded as influential in its day.
