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, and is still published today.
The daily edition of the Congressional Record is published daily when Congress is in session.
At the end of each session of Congress, all of the daily editions are collected, re-paginated, and re-indexed into a permanent, bound edition. This permanent edition, referred to as the Congressional Record (Bound Edition), is made up of one volume per session of Congress, with each volume published in multiple parts, each part containing approximately 10 to 20 days of Congressional proceedings.
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). These can be accessed through A Century of Lawmaking For a New Nation: U.S. Congressional Documents and Debates.
