The increasingly international nature of crime underscores the need for countries to work together to control crime and terrorism. For there to be effective and efficient cooperation on the international level, it is necessary for countries to understand the structure of other police systems. The World Police Encyclopedia fulfills this need by providing a systematic survey of the police systems of all the member nations in the United Nations and Taiwan.

Written in a clear and accessible style, the World Police Encyclopedia is an essential resource that scholars, students, and those involved in working to control international and domestic crime will turn to for fact-checking and as a solid starting point for wider research and exploration.
