Federal Legislative History Research: Before You Begin

Created by Law Librarian Emeritus Susan Lewis, updated by Khelani Clay

Beginning Your Legislative History Research


Your legislative research will be much easier if you locate as much as possible of the following information for each act:

  1. its Public Law number (or chapter number for laws passed before 1957);
  2. its location in the U.S. Statutes at Large;
  3. the date of enactment;
  4. the number of the House or Senate bill and Congress that was enacted.

Your online searching will be more precise if you use them; you will retrieve less irrelevant material.

What Is a Legislative History?

A legislative  history is a compilation of documents produced at each stage of the legislative (congressional) process.

How Is a Legislative History Used?

Legislative history documents may be used:

To aid a court in its interpretation of statutes, but only if:

  • The statutory language is unclear on its face;
  • No statutory canons exist to guide the court in its interpretation; and
  • There are no existing judicial or federal agency interpretations of the statutory language


to track a pending bill as it moves through Congress.
