The United States Constitution creates a federal government comprised of three separate and equal branches, and each are sources of law: legislative, executive, and judicial. In addition to the information below, the Law Library of Congress provides a helpful guide to federal legal materials.
The three branches of government in the United States (executive, legislative, and judicial) were created by The United States Constitution. If you are looking for executive orders, proposed/final regulations, or any other primary sources from the executive branch, please see our Administrative Law guide. If you are looking for federal legislation or legislative history, please see our Federal Legislative History guide. Information on how to find cases can be found on our Litigation guide, or any of our subject-specific research guides (e.g. Contracts Intellectual Property, etc.). Our Government Documents LibGuide also has links to many resources that could be helpful to you if you are looking for Federal Primary Materials.
