Large portions of public laws are enacted as amendments to the
United States Code. Once enacted into law, an Act will be published in the
Statutes at Large and will add to, modify, or delete some part of the United States Code. Provisions of a public law that contain only enacting clauses, effective dates, and similar matters are not generally
codified. Private laws also are not generally codified. Some portions of the United States Code have been enacted as
positive law and other portions have not been so enacted. In case of a conflict between the text of the
Statutes at Large and the text of a provision of the United States Code that has not been enacted as positive law, the text of the
Statutes at Large takes precedence. ==History==
