The Cambridge Companion to Queer Studies
by
This Companion provides a guide to queer inquiry in literary and cultural studies. The essays represent new and emerging areas, including transgender studies, indigenous studies, disability studies, queer of color critique, performance studies, and studies of digital culture. Rather than being organized around a set of literary texts defined by a particular theme, literary movement, or demographic, this volume foregrounds a queer critical approach that moves across a wide array of literary traditions, genres, historical periods, national contexts, and media. This book traces the intellectual and political emergence of queer studies, addresses relevant critical debates in the field, provides an overview of queer approaches to genres, and explains how queer approaches have transformed understandings of key concepts in multiple fields.
