b. Professional Training Series
The Professional Training series consists of handbooks and manuals intended to increase awareness of international standards and are directed at a specific target audience selected for its ability to influence the human rights situation at the national level. Although primarily designed to provide support to the training activities of the Technical Cooperation Programme of the OHCHR, these publications could also serve as practical tools for those organizations involved in human rights education to professional groups.
The training manuals in the Professional Training Series are adaptable to the particular needs and experience of a range of potential audiences within the target group, in terms of culture, education and history. Where appropriate, information on effective pedagogical techniques is included to assist trainers to use the manuals as effectively as possible.
Each manual or handbook is prepared with the assistance of experts in the relevant fields and is subject to extensive external review and appraisal. Where appropriate, manuals or handbooks are tested in training sessions prior to their finalization.

c. Human Rights Studies Series
The Human Rights Study Series reproduces studies and reports on important human rights issues prepared by experts of the Commission on Human Rights and the Sub-Commission on the Promotion and Protection of Human Rights (formerly Sub-commission on Prevention of Discrimination and Pro- tection of  Minorities) in accordance with their mandates.
