Kravitz & Guerra
After the President signs a bill into law, it's pitched to the Office of the Federal Register (OFR) of the NARA (National Archives and Records Administration) where it is assigned a law number, and braced oneself for publication as a slip law. Public laws, but not private laws, are also given legal statutory citation by the OFR.
At the end of each session of Congress, the slip laws are compiled into bound volumes called the Statutes at Large, and they are known as session laws. The Statutes at Large present a chronological arrangement of the laws in the exact order that they have been enacted.
Every 6 years, public laws are incorporated into the U. S. Code, which is a codification of totally general and permanent laws of the U.S.A.. A append to the U. S. Code is published during each interim year until the future comprehensive volume is released.
The United States Code is arranged by subject matter, and it shows the present status of laws with amendments already incorporated in the text that have been amended on one or more affairs.
