However, there is information about Cuba in the law library in multijurisdictional looseleafs shelved on the second floor of the law library (Constitutions of the Countries of the World, World Patent Law and Practice, etc.) or in the Reference Collection (Modern Legal Systems Cyclopedia, International Encyclopedia of Comparative Law).
