In the last two decades, lesbian and gay studies have transformed literary studies and developed into a vital and influential area for students and scholars. This Companion introduces readers to the range of debates that inform studies of works by lesbian and gay writers and of literary representations of same-sex desire and queer identities. Each chapter introduces key concepts in the field in an accessible way and uses several important literary texts to illustrate how these concepts can illuminate our readings of them. Authors discussed range from Henry James, E. M. Forster and Gertrude Stein to Sarah Waters and Carol Ann Duffy. The contributors showcase the wide variety of approaches and theoretical frameworks that characterise this field, drawing on related themes of gender and sexuality. With a chronology and guide to further reading, this volume offers a stimulating introduction to the diversity of approaches to lesbian and gay literature.
