The United States Code is the codification by subject matter of the general and permanent laws of the United States based on what is printed in the Statutes at Large. It is divided by broad subjects into 50 titles and published by the Office of law Revision Counsel of the U.S. House of Representatives.
The USC has been published since 1926 every six (6) years. To stay current, annual cumulative supplements are published in between the years. The GPO Access has the 1994, 2000, and now even the 2006 versions of the United States Code, including the annual supplements. Files are available in ASCII Text from the 1994 edition forward and Portable Document Format (PDF) from the 2006 edition forward.
