Book excerpt: Disability Incarcerated gathers thirteen contributions from an impressive array of fields. Taken together, these essays assert that a complex understanding of disability is crucial to an understanding of incarceration, and that we must expand what has come to be called 'incarceration.' The chapters in this book examine a host of sites, such as prisons, institutions for people with developmental disabilities, psychiatric hospitals, treatment centers, special education, detention centers, and group homes; explore why various sites should be understood as incarceration; and discuss the causes and effects of these sites historically and currently. This volume includes a preface by Professor Angela Y. Davis and an afterword by Professor Robert McRuer.
