The journal GLQ: A Journal of Lesbian and Gay Studies is where queer theory has defined and transformed itself. On the occasion of the GLQ’s twenty-fifth anniversary, the editors, authors, and readers of the journal commemorate its impact on the field. The issue includes an extended “GLQ Forum” that looks back at specific articles and special issues, examines the significance and impact of each, and includes critiques and considerations of how these key works continue to resonate. A special section highlights and reflects on the contributions of major theorists such as Cathy Cohen, Eve Kosofsky Sedgwick, and Susan Stryker.
