Concepción Arenal – Penitentiary Studies (2nd Edition, Madrid, 1877)

A landmark work by Concepción Arenal, one of the foremost Spanish jurists, criminologists, and social reformers of the nineteenth century. In this 1877 second edition, Arenal presents a comprehensive study of punishment, prison organization, and the reform of penitentiary institutions, advocating rehabilitation through education, labor, discipline, and moral improvement rather than mere punishment. The book examines European and American prison systems, solitary confinement, prisoner classification, recidivism, sentencing, and the treatment of women and juvenile offenders. A classic of criminal law and penitentiary science, it remains an essential reference for legal historians, criminologists, and collectors of rare legal works.
