Agencies authorized to make regulations submit proposed and final regulations for publication in the Federal Register. The Federal Register also includes agency notices and presidential documents, such as executive orders. There is a monthly index for the paper issues of the Federal Register. The microfiche edition has an annual index.
The National Archives’ Office of the Federal Register produces the Code of Federal Regulations, which codifies the permanent regulations published in the Federal Register. A non-permanent regulation, such as a regulation closing a river to boat traffic on a specific date, would not be codified. Volume three, also known as “The President” is not replaced when a new edition is published. Each year, an index volume is published.
Every month, the Office of the Federal Register produces List of Sections Affected, which provides Federal Register page numbers where one can find changes made to specific sections of the Code of Federal Regulations since the most recent replacement volume was published. Each quarter (typically March, June, September, and December), an issue is published that is to be kept for reference.
