This textbook examines prisons and imprisonment. Historically, prisons and prisoners have been a source of interest to the general public. However, despite near universal acceptance of imprisonment as a feature of society, we know relatively little about the reality of prison life, or the effects it has on individuals and communities. Using academic scholarship, empirical research, government papers, policy reports, and accounts from lived experiences of the institution, this book analyses the complexities and contradictions of prison life, the place of the prison in twenty-first century society, and its prospects for the future. This book will introduce readers to key debates surrounding the use of imprisonment, and challenge readers to interrogate conventional perspectives on an institution that reflects the society in which it is situated.
