This booklet gives an overview of IOM publications on trafficking in persons and other related issues. The publications cover different forms of exploitation in times of crisis involving labour migrants and other groups of vulnerable migrants, the challenges in doing research on human traffickers and trafficking operations, the health consequences of human trafficking, responses of stakeholders to combat trafficking in persons, and assisting and reintegrating victims of trafficking. In this series, there are also studies on areas where little research is done, such as the causes and consequences of re-trafficking.
