There are innumerable instances of the U.S. Constitution. Several sources provide historically interesting or helpfully annotated texts.
Often, state constitutions are best pursued through state law library websites. Researchers must understand the currency of the source consulted. See your liaison librarian and state law libraries for additional guidance.
Federal law is published as session law and code. State law follows a similar pattern. Federal laws can be found in Statutes at Large and the United States Code. Similar publications are available for each state. Consult your liaison librarian and state law libraries for additional guidance.
As its website notes, "The Uniform Law Commission (ULC, also known as the National Conference of Commissioners on Uniform State Laws), established in 1892, provides states with non-partisan, well-conceived and well-drafted legislation that brings clarity and stability to critical areas of state statutory law." For additional information, see the ULC's "About Us" page.
