Introduction to Women's, Gender & Sexuality Studies: Interdisciplinary and Intersectional Approaches, third edition, reflects the exciting changes taking place in this field. Emphasizing both interdisciplinarity and intersectionality, this innovative mix of anthology and textbook includes key primary historical sources and debates on contemporary issues. Readings from a range of genres and perspectives illustrate the diversity of the field. While many of the readings are foundational texts, the book also integrates new work from established scholars and emerging voices to expand current debates in the field. The text is enhanced by thorough overviews that begin each section that encourage students to think critically and self-reflexively. The addition of Act Now! A Feminist Toolkit for Twenty-first Century Activism to this edition enables students to take their theoretical classroom learning and apply it to activism in their daily lives and the broader world. Act Now! encourages students to use what they have learned to enact change.
