The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

Preemption is a doctrine of American constitutional law, under which states and local governments are deprived of their power to act in a given area, whether or not the state or local law, rule or action is in direct conflict with federal law. This book covers not only the basics of preemption but also focuses on such topics as federal mechanisms for agency preemption, implied forms of preemption, and defensive use of federal preemption in civil litigation.
