The Rights Track: Sound Evidence on Human Rights and Modern Slavery uses rich content from The Rights Track podcast [www.rightstrack.org] in an innovative book that enhances and enriches our understanding of the human rights challenges facing the world today. This book showcases the important role of evidence in tackling those challenges and explores the medium of podcasting as a tool for discussing how research evidence is used to protect and promote human rights.  The book is situated in the context of the post-9/11 era and the many geo-political changes that have taken place over the first two decades of the twenty-first century. Its motivation is to (1) demonstrate the healthy and inspiring work being carried out on multiple dimensions of human rights, (2) capture the different kinds of insights and knowledge about human rights through the dialogic and conversational format of podcasts, and (3) illustrate the enduring importance of human rights, particularly during increasingly challenging times. Each series of the podcast has been structured around big questions in the field of human rights, which have evolved thematically over six years (2015-2021).  The book also groups these big questions thematically, where the text is written for a general audience and in a user-friendly style. Part I provides the background and context for the content. Part II addresses significant human rights themes ranging from human rights mobilisation to human rights in times of the COVID-19 pandemic. Part III addresses the global challenge of modern slavery, a United Nations Sustainable Development Goal aimed to help more than 40 million enslaved people in the world today. Part IV provides a stock take and projection for the future of human rights. The dialogic and conversational format of the podcasts provide a rich source of human rights content that stays close to the voice of the very people seeking to advance human rights.
