How-to & Library Resources


Last Updated 3/2018

1. Starting with a U.S.C., U.S.C.A. or U.S.C.S. citation:

Use the historical notes at the end of the citation to find the Public Law number. Many sections of the U.S. Code will have multiple P.L. numbers as the sections have been amended multiple times. It is helpful to know the approximate date the law passed to zero in on the relevant Public Law.

2. Starting with the Popular Name of the legislation:

Find the Public Law number in Shepard's Acts by Popular Name (REF KF 90. S52) or look in the popular name tables in the pamphlets at the end of the U.S.C.A. or U.S.C.S.

3. When you know the Public Law number:


  • For the years 1970 to 2008, use the CIS Index (DOCREF KF 49.C62) to find a summary of the legislative history. CIS Legislative Histories from 1970 to date are also available through Proquest Congressional Publications available at (available on site or with Rutgers University log-in).
  • For legislation passed from 1973 to the present, use (, a legislative database maintained by the Library of Congress. can be searched using the bill number or public law number.  One can also check the status of pending legislation through For more recent legislation, provides hyperlinks to many of the relevant documents, including the Congressional Record, reports and hearings. The text of the hearings usually contains only the prepared statements submitted by witnesses, not actual testimony.
  • The U.S. Code Congressional & Administrative News USCCAN (DOCREF KF 48. U54) contains the full text of Public Laws from 1941 to the present. Beginning in 1948 it contains legislative history summaries. The summaries are not as complete as those found in the CIS Index or on Thomas. Selected House and Senate Reports can be found in USCCAN, but the text of the reports may be redacted. Where possible obtain the text of reports from the Serial Set.
  • At the end of the Congressional Record Index volume, or after 195?, in the Congressional Record Daily Digest Volume, there is a brief summary history of bills passed that year. The summary includes committee report numbers.
  • Lexis and Westlaw - Both online services offer some legislative materials. Westlaw's coverage includes House and Senate committee reports (as reported in USCCAN 1948-1989 with comprehensive coverage starting in 1990) and the Congressional Record (from 99th Congress to today).  Lexis has all committee reports since 1990 and the Congressional Record from 1985 to today.  For current legislation, Lexis and Westlaw may offer more comprehensive coverage than print sources.

5. Finding Compiled Legislative Histories:

In most cases it is necessary to compile a legislative history from scratch by locating all of the relevant documents listed above. But for some major legislative acts there may exist published legislative histories that bring together all of the relevant documents and may also contain added commentary and analysis by the author(s). Many of these compiled legislative histories are published by the staff of congressional committees (usually as Committee Prints) or the Congressional Research Service. Legislative histories are also published by executive agencies or by legal scholars as law review articles. Checking for the existence of a compiled legislative history can save the researcher a great deal of time and effort.

There are two major indexes for finding compiled legislative histories:

  • Johnson, Nancy P., Sources of Compiled Legislative Histories. Buffalo, N.Y.: William S. Hein & Co., 2012. [DOCREF- KF 42.2 .S68 2012]

    This work covers laws passed from the 1st through the 110th Congress.

  • Reams, Bernard D., Federal Legislative Histories: An Annotated Bibliography and Index to Officially Published Sources. Westport, CT: Greenwood Press, 1994. [DOCREF KF 42.2 1994]

    This work is limited to legislative histories published by official government sources (Committee Prints or works by executive agencies). It covers laws passed from the 1st through 101st Congress. Though the scope is narrower than the Nancy Johnson work it contains some histories not covered in the Johnson index.

The Law Librarians' Society of Washington, DC maintains a listing of compiled legislative histories available online at

HeinOnline includes the full text of many compiled legislative histories through its US Federal Legislative History Library, available at

Compiled legislative histories are also available through Lexis and Westlaw. Westlaw features the Arnold & Porter legislative history database that contains the full text of legislative documents for about two dozen major laws. Additionally, Westlaw also has three practice specific legislative databases for immigration law, securities & blue sky law and taxation. The CIS Congressional Universe is a subscription database available from Lexis that provides full legislative histories with hyperlinks to all of the associated documents for legislation from 1970 to the present. It is not available through the basic Lexis account and Rutgers does not have a subscription to this database.
