‘Intersectionality: A Foundations and Frontiers Reader’ is an accessible, primary-source driven exploration of intersectionality in sociology and related fields. The book maps the origins of the concept, particularly in Black feminist thought and sociology, opens the discourse to challenges and applications across disciplines and outside academia, and explores the leading edges of scholarship to reveal important new directions for inquiry and activism. Charting the development of intersectionality as an intellectual and political movement, Patrick R. Grzanka brings together in one text both foundational readings and emerging classics. Original material includes: Grzanka’s nuanced introduction which provides broad context and poses guiding questions; thematic unit introductions; author biographies and suggestions for further reading to ground each excerpt; and a conclusion by Bonnie Thornton Dill reflecting on the past, present, and future of intersectionality. With its balanced mix of analytical, applied, and original content, Intersectionality is an essential component of any course on race, class, and gender, feminist theory, or social inequalities.
