"The United States Code is the official codification of the general and permanent laws of the United States of America. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second Session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First Session, enacted between January 2, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 U.S.C. 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office"--Preface.

The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

Chief Justice John Marshall argued that a constitution "requires that only its great outlines should be marked [and] its important objects designated." Ours is "intended to endure for ages to come, and consequently, to be adapted to the various crises of human affairs." In recent years, Marshall's great truths have been challenged by proponents of originalism and strict construction. Such legal thinkers as Supreme Court Justice Antonin Scalia argue that the Constitution must be construed and applied as it was when the Framers wrote it. In Keeping Faith with the Constitution, three legal authorities make the case for Marshall's vision. They describe their approach as "constitutional fidelity"--not to how the Framers would have applied the Constitution, but to the text and principles of the Constitution itself. The original understanding of the text is one source of interpretation, but not the only one; to preserve the meaning and authority of the document, to keep it vital, applications of the Constitution must be shaped by precedent, historical experience, practical consequence, and societal change. The authors range across the history of constitutional interpretation to show how this approach has been the source of our greatest advances, from Brown v. Board of Education to the New Deal, from the Miranda decision to the expansion of women's rights. They delve into the complexities of voting rights, the malapportionment of legislative districts, speech freedoms, civil liberties and the War on Terror, and the evolution of checks and balances. The Constitution's framers could never have imagined DNA, global warming, or even women's equality. Yet these and many more realities shape our lives and outlook. Our Constitution will remain vital into our changing future, the authors write, if judges remain true to this rich tradition of adaptation and fidelity.
