This manual is one component of the four-part publication Human Rights and Prisons – a human rights training package for prison officials. The four components are designed to complement each other and, taken together, provide all necessary elements for the conduct of human rights training programmes for prison officials, under the training approach developed by the Office of the United Nations High Commissioner for Human Rights. This manual (component one of the package) provides in-depth information on sources, systems and standards for human rights relating to the work of prison officials, practical recommendations, topics for discussion, case studies and checklists.
