Emphasizing the diversity of collage in the twentieth century, Rona Cran's book explores the role that it played in the work of Joseph Cornell, William Burroughs, Frank O'Hara, and Bob Dylan. Collage's catalytic effect, Cran argues, enabled each to overcome a crisis in representation that threatened to destabilize their work. Throughout, she shows that rigid definitions of collage severely limit our understanding of artists and writers who used it in non-traditional ways.
