Once a bill is signed into law by the President, it is published as an individual "slip law" and assigned a chronological number based on the Congress in session in which it passed. Therefore, Public Law 95-336 was the 336th law passed by the 95th Congress. Slip laws are then reprinted in the bound set called the United States Statutes at Large. The Statutes maintain the same chronological sequence as the slip laws; however, the volumes have numbers unrelated to the sessions of Congress. In which case, Public Law 95-336 can be found at Statutes at Large volume 92, page 451 and is properly cited as 92 Stat. 451.

The statutes are then organized ("codified") by subject in the United States Code. The Code compiles all the laws in effect on a given date into 53 subjects, called titles. As such, Public Law 95-366 becomes 21 USC §1001. The Code is recodified every six years and is kept up to date with an annual cumulative supplement. The United States Code Annotated is a commercially produced (Thomson Reuters) version of the United States Code which adds case notes, history, and commentary to each Code section. USCA is updated by annual cumulative pocket parts and pamphlet supplements which can be published up to a year faster than those for the official version. An online version of the Code is also available from govinfo.gov as well as other sources.

Finding Statutes By Subject

To find a law by subject, start with the United States Code database from govinfo.gov. Then update your search in the Public and Private Laws database, also in govinfo.gov, to find any new legislation on the subject. To be complete, also check the index of the print set United States Code Annotated. If you cannot find the law you are looking for in one of the govinfo.gov databases or USCA, read up on the subject in American Jurisprudence, 2nd edition (KF 75 .A47 1962 Reference). The library's print set was cancelled in 2003, but it may be a good starting point to introduce you to the online version in Westlaw (to access in Westlaw click on "Secondary Sources"). Case law governs some areas of law more than statutory law (contracts, for instance). AmJur should give you some feel for that.

Finding Statutes by Name

To find a law by its popular name, start with one of the online versions of the Table of Popular Names. Also, print versions are shelved with the USCA and the USC.  For a very recent law, you may need to search Public and Private Laws in govinfo.gov, although popular names are not always included in the actual text of the act. You may also find a reference to the bill in CQ Magazine or a newspaper article which gives the public law number. Follow the link to Public Laws on Congress.gov to see the public laws from the current congressional session (other lists of public laws available back to 1973). The Congressional Record also records the public law number when a law is passed.

Before 1973

If the law was passed before the 93rd Congress (1973-1974), you will need to scan the spines of the print volumes of the Statutes at Large to find the appropriate volumes. You should then check the title pages of each volume for the correct range of public laws. Once you have the correct volume and part, the "List of Public Laws" will give you the page number where the law begins.

United States Statutes at Large, 1903 - (Documents)
  • AE 2.111:vol (1984 - )
  • GS 4.111:vol (1949 - 1983)

  • microfiche (1799 - 1948), shelved in CRS microfiche cabinet

Contains public and private laws, concurrent resolutions, and proclamations passed by Congress and signed by the President. Each volume also has a subject and name index.

Updating a Public Law

To find the current status of a very recent law when you have the public law number, use the US Code Classification Tables below. For an earlier law, search one of the electronic versions of the United States Code AND check the Tables volume of USCA.

United States Code Classification Tables (Office of the Law Revision Counsel, U.S. House of Representatives)
Organizes public laws by public law number and by Code section. Use the table sorted by Public Law number to determine which sections of the Code will be affected by a particular law. Use the table sorted by Code section to find out whether a particular section of the Code has recently been amended.
United States Code Annotated, annual.
KF 62 .W45 (Reference). Reprints the official code but adds historical notes, cross references, references to key numbers in West's digest system, and extensive case notes. Use the Tables volumes, making sure to use all three volumes -- the bound volume, a bound cumulative supplement, and a pamphlet cumulative supplement. The Table is laid out in chronological order and will refer you from the public law number to the title and section of the USC and USCA. The Table will also tell you if the law has been eliminated or repealed. For recent legislation, remember to check the Tables section in the pamphlet supplement. WTAMU students, faculty, and staff can also search the online USCA Tables by public law number.
