This respected resource is a great starting place for criminal law research, as it covers the history of various criminal law principles, developments, and the present status of the law. It also contains an extensive list of defenses - both generally and as they apply to specific offenses such as burglary, forgery, libel, homicide, and more. One of the assets of this set is the thorough primary and secondary law annotations, with a particular focus on A.L.R articles. It also provides both state and federal analysis, as well as an in depth look at the Model Penal Code.
