US Constitutional Law (USC) provides a comprehensive research resource on the law, politics, and history of constitutionalism in the United States at the federal and state levels. Combining extensive primary materials with expert commentary, the service provides researchers with unparalleled access to the historical development of federal and state constitutionalism.

At launch, the resource features the full text of current and historical state constitutions as well as the Oxford Commentaries on the State Constitutions of the US series, offering article-by-article commentaries on every State Constitution, tracing their historical development.

This site is powered by the Oxford Law Citator, so that researchers can instantly follow citations between documents, while a powerful browse functionality allows users to look across resources by subject, jurisdiction, and chronology.

Moving forward, US Constitutional Law will be continuously expanded and updated with a rich archive of primary materials and secondary literature covering the full historical sweep of American State and Federal constitutionalism. The resource will be invaluable to all students, researchers, and lawyers looking to understand American Constitutionalism whether they are inside or outside the US.
