incorporating social, economic, and political history, they included contemporary issues and women's contributions to civilization. Margaret Crocco points out that the interdisciplinary approach the Beards used in their textbooks encouraged the development of academic programs in American society in the 1930s and 1940s at colleges and universities including Yale University, Brown University, the University of Minnesota, and the University of Pennsylvania. Mary was retroactively elected to membership in Phi Beta Kappa in 1939. (In 1897, when she graduated from DePauw University, only males were awarded this academic honor.) In History and Feminism: A Glass Half Full (1993), Judith Zinsser argues that beginning in the 1930s, Mary Beard "was the most well-known authority and advocate for women's history in the United States." Beard's writings and the actions she took during her life on behalf of women's suffrage, labor issues, and establishment of women's archives also helped to illuminate the contributions that women made throughout history. By end of twentieth century, other historians began to consciously integrate women's contributions to history in their publications such as Howard Zinn's revision of A People's History of the United States (rev. 1995). Margaret Crocco concluded that Mary Beard's perspectives on women's history, in general, and Beard's contention that women have also been active agents in history "remain at the forefront of the field today." In The Majority Finds Its Past: Placing Women in History (1979), historian Gerda Lerner described the ongoing efforts to write about women's history as continuing the work that Beard had begun. Although Beard's work to establish a women's archive in New York City was unsuccessful, she consulted on other women's archive initiatives that eventually lead to the establishment of the Schlesinger Library at the Radcliffe Institute for Advanced Study at Harvard University, as well as the Sophia Smith Collection at the Neilson Library at Smith College, and other women's history projects such as those in New Jersey. One of Mary Beard's indirect legacies was the development of women's history courses, which have become standard offerings on American college campuses. Her work "A Changing Political Economy as It Affects American Women" is an early example of a women's history course syllabus. Women's history has evolved into an academic field of study. In 1970, the Indiana University-South Bend campus began what is the oldest continuing women's studies program in the United States.
