Additional sources of information on the histories of bills or legislative histories


What is bill tracking?

To understand a bill's progress toward becoming a public law (or not), some databases have "bill history" or "bill tracking" sections where researchers can follow the chronological sequence of actions on a bill, its current status, and locate the associated publications.

What is a legislative history?

A legislative history is a list of the steps that a particular piece of legislation went through and the associated documents. A legislative history might be used to answer questions such as:

  • What steps did a bill take in Congress? What documents were produced at each step?
  • What was the intent of Congress?
  • What arguments for and against the legislation were made?
  • Who were the leaders associated with the legislation?
