This Major Reference Work synthesizes the global knowledge on cybercrime from the leading international criminologists and scholars across the social sciences. The constant evolution of technology and our relationship to devices and their misuse creates a complex challenge requiring interdisciplinary knowledge and exploration. This work addresses this need by bringing disparate areas of social science research on cybercrime together. It covers the foundations, history and theoretical aspects of cybercrime, followed by four key sections on the main types of cybercrime: cyber-tresspass, cyber-deception/theft, cyber-porn and obscenity, and cyber-violence, including policy responses to cybercrime. This work will not only demonstrate the current knowledge of cybercrime but also its limitations and directions for future study.
