The FBI is romanticized, feared, criticized and admired. Because of its strong impact on American public life, it is the focus of interest and research by students and professionals studying history, politics, law, criminal justice and law enforcement. This is a complete reference work on this powerful organization. This new guide focuses on the history, role, powers, influence, organization, people and cases of the FBI. Organized into ten subject-defined sections, each with its own table of contents, this work is readable from cover to cover, as well as useful for reference look-up of specific topics. A selected annotated bibliography is also included, as is an appendix giving key statistics on staff sizes and appropriations since 1908.
