Since the publication of the second edition of this bibliography in 1987, the focus of writing and research on women in business, labor, and economics has remained faithful to several constants: the documentation and analysis of occupational sex segregation, equal employment, and the important work of recovering the histories of working women in blue-collar as well as professional jobs. One category—the needs of working mothers—has arguably been expanded to include the notion of working families even as the research shows that women still do most of the housework and child care in addition to any paid job they may have outside the home, and that divorced women and single mothers still suffer economically. Women's work and women working remain cultural referents in needs of further definition. Subjects represented in this section include women and work (including international aspects and race/ethnicity), feminist economic theory, sexual harassment in the workplace, comparable worth, glass ceilings, nontraditional careers, unions and the labor movement, economic and labor histories, unpaid household labor, sex segregation in careers/professions, independent wage earners, women/gender (race/ethnicity) in segregation in careers/professions, international economic development/conditions, technology in the workplace, and blue-collar workers. The "Monographs" section is subdivided into three categories: "Economics, Development, and Globalization"; "Business, Entrepreneurship, and Labor"; and "Workplace Issues, Unions, and Activism."
