This edited collection speaks to and expands on existing debates around incarceration. Rather than focusing on the bricks and mortar of institutional spaces, this volume’s inventive engagements in ‘thinking through carcerality’ touch on more elusive concepts of identity, memory and internal – as well as physical – walls and bars. Edited by two human geographers, and positioned within a criminological context, this original collection draws together essays by geographers and criminologists with a keen interest in carceral studies. The authors stretch their disciplinary boundaries; tackling a range of contemporary literatures to engage in new conversations and raising important questions within current debates on incarceration. A highly interdisciplinary project, this edited collection will be of particular interest to scholars of the criminal justice system, social policy, and spatial carceral studies.
