"Unequal Sisters" has become a beloved and classic reader in American Women's History. It provides an unparalleled resource for understanding women's history in the United States today. When it was first published in 1990, it revolutionized the field with its broad multicultural approach, and continued, through its next two editions, to emphasize feminist perspectives on race, ethnicity, region, and sexuality. This classic work is in its fourth edition, and has incorporated the feedback of end-users in the field, to make it the most user-friendly version to date.
