About the Library of Congress
The Library of Congress
The Library of Congress is the largest library in the world, with millions of books, recordings, photographs, newspapers, maps and manuscripts in its collections. The Library houses the Congressional Research Service (CRS), the main research arm of the United States Congress. By statute, Congress has directed the Librarian of Congress to revise and update the Constitution Annotated on a periodic basis, a task completed by the attorneys in CRS.
The Librarian of Congress, through the work of CRS’s constitutional scholars, fulfills her statutory obligations imposed by Congress to provide the Constitution Annotated. Beyond fulfilling a statutory mandate, the Constitution Annotated serves the Library’s fundamental mission of educating the public through authoritative, objective, and non-partisan analysis.
