The congressional Record is a daily journal listing the debates, proceedings and activities (including floor votes) of both the House and Senate as well as Congress (jointly). The Daily edition is published the following day and stands individually (as a daily collection of around 275 pages each) until bound in final form at the end of the current session of congress.
The Congressional Record is the 4th in the series of documents that have recorded the activity of Congress. That is to say, the name of this serial changed four times since the inception of the United States. In chronological sequence, here are the names and dates of coverage.
