Search & Browse the U.S. Constitution Online

In celebration of Constitution Day, I want to highlight an amazing resource available freely on the web: The Constitution Annotated: Analysis and Interpretation of the U.S. Constitution.

The Constitution Annotated includes an explanation of the meaning of the Constitution, broken down Article by Article, Section by Section, and Clause by Clause. The explanation is direct and understandable, and it is heavily footnoted to the resources such as United States Supreme Court opinions that have historically interpreted the Constitution. 

Hosted by congress.gov and prepared by the American Law Division of the Congressional Research Service, this is a HUGE resource. In print, it is over 3,000 pages! The online version has functionality that makes it even more useful. For example, you can search using simple keywords. You can filter and refine your results to focus on articles, amendments, topics, and resources.

Researchers who would prefer to browse are easily able to do so.

For those who wish to review Constitution adjacent information, that is also available. The site includes a number of Tables—every researcher’s favorite! There is a Table of Laws Held Unconstitutional in Whole or in Part, a Table of Supreme Court Justices, and a Table of Supreme Court Decisions Overruled by Subsequent Decisions.

In addition to being a helpful resource to consider in beginning research on a constitutional law research problem, this website has the potential for helping a researcher identify trends in constitutional law over time. The site includes links to additional U.S. Constitutional Resources that are available through the Library of Congress.

Come by the library and visit our print copy—for today it is at the reference desk, regularly it’s located in the Reference Collection—or check it out online!
