The selective bibliography presented here focuses on interdisciplinary research developed over the past 6 years on three major themes for the prevention of radicalization, violent extremism and online hate speech. We wanted to gather in one bibliography at a time: Research that describes and understands the processes of online radicalization, encompassing terrorist propaganda, extremist activism and online recruitment processes. Research that promotes the construction of conceptual, technical, and methodological tools for the analysis and characterization of hate and extremist discourse. Evaluative research on counter-discourse or counter-narrative deployment policies by seeking to take stock of evaluations, impact measures and innovations. Technological research using big datas, datasphere analysis, development of effective action tools to fight online terrorism and online extremism. We are aware that this list is dated from 2015 to 2021. We strive to describe each result and provide a comprehensive literature review that selects the best research advances. We hope you find this bibliography useful in answering the three key social questions when addressing these areas: Are you sure that the digital world has become a space for radicalization and extremist recruitment? But how can we limit, on a regular basis, these dangers on the Internet? But is the fight possible? How to act on a daily basis.
