Federal Legislation and Statutes

Scope and Access

The first issuance of an enacted law passed by the United States Congress is a slip law. This pamphlet contains the text of a single act and is individually paginated. At the end of each legislative session, the slip laws are consolidated and arranged chronologically into a permanent set of bound volumes called session laws. Codes are the subject arrangement of session laws. Annotated codes provide citations to law reviews, legal encyclopedias and other reference sources as well as abstracts of cases decided on that point of law.

Slip Laws

Each enacted law is assigned a public law number or a private law number. Public laws are intended to be for wide application whereas private laws are intended for individuals or small groups of people. Private laws and public laws have their own numbering. Few private laws are passed during a legislative session.

The heading of a slip law contains the public law number, the date it was approved and the session law cite. Below that is the text of the enacted law. Marginal notes provide the bill number that introduced the law, the date of approval, the name of the act, and the United States Code citation. Also in the margins are headings that direct to specific points in the law. At the end of the slip law is a brief legislative history. It provides references to House and Senate reports as well as Congressional debates.

Slip laws are slow to appear and researchers often use privately published resources to obtain current and timely information on recently enacted legislation.

The first number designates in which Congress the law was enacted. The second number represents the chronological sequence of enactment by Congress.


Session Laws: United States Statutes at Large

The United States Statutes at Large is an official publication of the United States and is the permanent bound collection of slip laws. It is issued at the end of each legislative session. The Statutes at Large is published slowly and there is a lag time of two to three years from the end of the legislative session to the time that they are published.

Currently, session laws are the authoritative binding text of federal law or positive law of legislation. However, Congress is currently engaged in a project to enact each title of the Code as positive law. For more information, please refer to the preface in the 2000 edition of the United States Code (page vii).

Although publication did not begin until 1846, the Statutes at Large retrospectively covers public and private laws enacted since 1789 and treaties since 1778. Until 1951, ratified treaties were included in the Statutes at Large. This was discontinued when the government began publishing U.S. Treaties and Other International Agreements (Gov. Docs. S 9.12:). Ratified treaties now appear in this separate publication.

Since 1938, each volume of Statutes at Large contains laws enacted during a legislative session. Before that, several legislative sessions had been combined into one volume. Statutes at Large is arranged with the text of the public laws first, followed by private laws, concurrent resolutions and proclamations. The layout for the text of the enacted laws is the same as discussed in the above slip laws section. One exception is bill numbers, which did not appear in Statutes at Large until 1904. Bill numbers for these years can be located in the following title, Legislative Reference Checklist: The Key to Legislative Histories from 1789-1903 (KF49 .I43 1982 ).

Code: United States Code

The United States Code is a subject or topical arrangement of all public laws in effect at the time of printing. The code only contains the permanent laws that are in force at the time of publication and removes repealed laws and revised laws that have been amended by Congress.

The United States Code is the official federal code and is published by the United States Government. The current format for the Code was established in 1926. It has 52 titles. Each title is divided into chapters and further subdivided into sections. A new edition is reissued every six years and is updated annually with cumulative bound supplements. The United States Code is published slowly and can be from eight months to four years out of date.

The United States Code does not reflect judicial decision-making. If a court declared a statute unconstitutional, no indication of this would appear until the legislature either amended or repealed the statute.

At the end of each section of the code is historical information on the statute. It states when the law went into effect and any amendments made to the act since then. It gives the date of enactment and provides references to the Statutes at Large cite and the public law number, which enables the user to locate the original text and to locate any legislative history materials relating to the enactment. Codification and amendment sections follow providing information about the statute.

Annotated Codes: United States Code Service and United States Code Annotated

Annotated codes are published by private publishers and are unofficial federal codes. Annotated codes have all of the same features of the U.S. Code, but also provide annotations to statutes and are updated more frequently. The United States Code Service (USCS) and United States Code Annotated (USCA) are two annotated codes.

The USCS and USCA maintain the same title and section numbering found in the U.S. Code. However, the USCS follows more closely the context and language used in the Statutes at Large (using notes for clarification), while the USCA follows the language of the U.S. Code more closely.

USCS and USCA provide annotations to supplement the statute. They provide historical notes, which can be used to research the language of the statute as it was enacted and its amendments. The notes give the date of enactment, the public law number, and the Statutes at Large cite. There are also brief comments about amendments, or revisions made to the statute.

If there is a complimentary Code of Federal Regulations section, it will be included in the annotations as well as any cross-references to other USCS or USCA citations. A research guide follows providing references to treatises, the American Law Reports (ALR), law reviews and legal encyclopedias. The USCS cites to the legal encyclopedia, American Jurisprudence 2d and USCA cites to Corpus Juris Secundum.

A Notes and Decisions section follows which contains brief abstracts of cases discussing the particular statute. The USCS includes judicial and administrative decisions, while USCA contains judicial decisions only. USCA is more comprehensive in the judicial decisions it includes. The USCS does not include all decisions on the statute; it excludes those that are obsolete or repetitive.

USCS and USCA are updated more frequently than the U.S. Code. Pocket parts and pamphlets are issued yearly to update the main volume. Throughout the year, advance annotation supplements are issued containing the most current annotations. Monthly, advance legislative services are published which has the text of recently enacted laws, executive documents, court rules, and selected regulations with tables indicating which code sections have been affected by recent legislative action.
