This is a chronological, but still incomplete, list of United States federal legislation.
At the federal level in the United States, legislation (i.e., "statutes" or "statutory law") consists exclusively of Acts passed by the Congress of the United States and its predecessor, the Continental Congress, that were either signed into law by the President or passed by Congress after a presidential veto.
Acts of Congress are published in the United States Statutes at Large.
Volumes 1 through 18, which have all the statutes passed from 1789 to 1875, are available on-line at the Library of Congress, here.
This numbering included both laws applicable to the general public and laws relating to specific individuals, e.g., to grant pensions to disabled veterans.
