Kathy Acker’s body of work is one of the most significant collections of experimental writing in English. In Kathy Acker: Writing the Impossible, Georgina Colby explores the compositional processes and intricate experimental practices Acker employed in her work, from early poetic exercises written in the 1970s to her final writings in 1997. Through original archival research, Colby traces the stages in Acker’s compositional processes and draws on her knowledge of Acker’s unpublished manuscripts, notebooks, essays, illustrations, and correspondence to produce new ways of reading Acker’s works. Rather than treating Acker as a postmodern writer this book argues that Acker continued a radical modernist engagement with the crisis of language, and carried out a series of experiments in composition and writing that are comparable in scope and rigor to her modernist predecessors Stein and Joyce. Each chapter focuses on a particular compositional method and insists on the importance of avant-garde experiment to the process of making new non-conventional modes of meaning. Combining close attention to the form of Acker’s experimental writings with a consideration of the literary cultures from which she emerged, Colby positions Acker as a key figure in the American avant-garde, and a pioneer of contemporary experimental women’s writing.
