Statutes enacted by a legislature are arranged by topic and published as part of jurisdiction's code. The federal government publishes federal code; each state published its own state code.
Regulations come from administrative agencies and the executive branch.

The Code of Federal Regulations, the current rules from the Executive Branch of the U.S. Federal Government.
The Federal Register, which publishes rules and regulations from the Executive Branch of the U.S. Federal Government beginning in 1936.
