The Congressional Record consists of four sections: the House section, the Senate section, the Extensions of Remarks, and, since the 1940s, the Daily Digest. At the back of each daily issue is the Daily Digest, which summarizes the day's floor and committee activities and serves as a table of contents for each issue. The House and Senate sections contain proceedings for the separate chambers of Congress.
A section of the Congressional Record titled Extensions of Remarks contains speeches, tributes and other extraneous words that were not actually uttered during open proceedings of the full Senate or of the full House of Representatives. In years past, this particular section of the Congressional Record was called the "Appendix". While members of either body may insert material into Extensions of Remarks, Senators rarely do so. The overwhelming majority of what is found there is entered at the request of Members of the House of Representatives. From a legal standpoint, most materials in the Congressional Record are classified as secondary authority.
By custom and rules of each house, members also frequently "revise and extend" the remarks they actually made on the floor before the debates are published in the Congressional Record. Therefore, for many years, speeches that were not actually delivered in Congress appeared in the Congressional Record, including in the sections purporting to be verbatim reports of debates. In recent years, however, these revised remarks have been preceded by a "bullet" symbol or, more recently and currently, printed in a typeface discernibly different from that used to report words actually spoken by members.
The Constitution, in Article I, Section 5, requires Congress to keep a journal of its proceedings, although the House and Senate Journals are separate publications from the Congressional Record, and include only a record of actions and votes, rather than verbatim texts of the debates.
The Congressional Record was first published in 1873. Prior to this, proceedings, roll calls, debates, and other records were recorded in The Debates and Proceedings in the Congress of the United States (1789–1824), the Register of Debates in Congress (1824–1837), or the Congressional Globe (1833–1873). A digital collection of these historical volumes is now available online via the Library of Congress.
