The Compendium combines the perspectives of the OSCE Office for Democratic Institutions and Human Rights (ODIHR)’s work on identity management and freedom of movement, and the OSCE Transnational Threats Department’s work on travel document security. It is the result of consultations initiated in 2013, and the subsequent process has included a series of expert meetings and a detailed questionnaire distributed to all OSCE participating States in August 2016.
