The collection examines the relationship between illicit markets and the economic functioning of organized crime, highlighting how activities such as drug trafficking, human trafficking, arms trafficking, and the use of cryptoassets generate and move large volumes of illicit funds that are later integrated into the formal economy through asset laundering.

The featured collection is grounded in these principles: to present public security professionals and criminal justice practitioners with new security perspectives in a transnational context.

The collection brings together introductory materials and applied studies on the use of Social Network Analysis (SNA) in criminal investigations. It presents the theoretical foundations, methods, and metrics used to map connections between individuals and organizations, identify strategic targets, and detect vulnerabilities within criminal structures. The approach integrates knowledge from sociology, mathematics, and criminology, supporting evidence-based law enforcement actions and strategic decision-making.

The collection addresses cooperation mechanisms between judicial and law enforcement systems in the prevention and suppression of organized crime, corruption, and other forms of transnational crime. It brings together studies, treaties, and documents on extradition, the production and sharing of evidence, asset recovery, and joint investigation teams, highlighting experiences and regulatory frameworks from different regions.
