United States Statutes at Large
The United States Statutes at Large, commonly referred to as the Statutes at Large and abbreviated Stat. , is the official record of Acts of Congress and concurrent resolutions passed by the United States Congress. Each act and resolution of Congress is called a slip law, which is classified as either public law (abbreviated Pub. L.) or private law (Pvt. L.), and designated and numbered accordingly. At the end of a Congress session, slip laws (now commonly called session laws) are compiled into Statutes at Large, which are numbered and organised by Congress session. They are part of a three-part model for publication of federal statutes consisting of slip laws, session laws (Statutes at Large), and codification (United States Code).
