The articles in this 20th anniversary double issue address the ways in which the politics of racism and sexism organize what knowledge is and how we learn, incorporate, resist, and transform it. Many of the articles in Part 1, "Racism, Sexism, Knowledge and the Academy," explore and analyze racism within the academy, including the discipline of Women's Studies. The potentially transformative, empowering, and politically subversive nature of feminist academic work, both inside and outside of Women's Studies programs, is also taken up in this section. The writings in Part 2, "Politics, Identity and Organizing," address issues of location, identity and social change. Some of the contributions to this section are grounded in personal experience. All of the pieces in some way take up diverse aspects of the way women's oppression is socially organized.
