Legal Research at Princeton: U.S. Law: Regulations

Introduction to Regulations

Regulations and administrative law refer to the regulations (also called rules) promulgated by administrative agencies, both on the federal and state levels.  Similar to statutes, regulations are published chronologically and then codified into a subject-based code of regulations.

Federal Regulations

Federal Regulations are chronologically published in the daily Federal Register (Fed. Reg). This daily publication publishes both proposed and final regulations, executive orders and other official documents from the executive branch and is sometimes referred to as the executive branch’s “daily newspaper.”  Next, the regulation codified in the Code of Federal Regulations (C.F.R.).  This set contains the current federal regulations in force organized by subject.
