About The Constitution of the United States of America: Analysis and Interpretation


The Constitution of the United States of America: Analysis and Interpretation, popularly known as the Constitution Annotated, encompasses the U.S. Constitution and analysis and interpretation of the U.S. Constitution with in-text annotations of cases decided by the Supreme Court of the United States.


The U.S. Constitution comprises the primary law of the U.S. Federal Government. It describes the three chief branches of the Federal Government and their jurisdictions, and lays out the basic rights of citizens of the United States. The U.S. Constitution is the oldest Federal constitution in existence and was framed by a convention of delegates from twelve of the thirteen original states in Philadelphia in May 1787, Rhode Island failing to send a delegate. The U.S. Constitution is the landmark legal document of the United States.


FDsys provides access to Constitution Annotated editions and supplements from 1992 forward. The volume has been published as a bound edition every ten years, with cumulative updates issued in the intervening years biannually as inserts that address new constitutional case law, primarily from U.S. Supreme Court decisions. The analysis is provided by the Congressional Research Service (CRS) at the Library of Congress.


New Resources


In 2013, new resources were introduced to coincide with the release of the 100th anniversary edition of the Constitution Annotated. This includes a frequently revised “digital update” version on FDsys. Beginning with the 2012 centennial edition of the Constitution Annotated, interim digital updates are made available in PDF several times a year on an irregular basis. The first update includes analysis for the 2012 edition up to June 26, 2013. All new resources beginning with the 2012 edition have GPO’s Seal of Authenticity on every page.


Also in 2013, the Library of Congress began using the PDF files produced by GPO to power a Constitution Annotated mobile app. The app can be downloaded for free from iTunes. An Android version is under development.
