Cornell LII as legal citation incumbentLegal Information Institute

The Legal Information Institute (LII) at Cornell Law School has published primary legal materials free online since 1992. It hosts the United States Code, the Code of Federal Regulations, the Federal Rules, Supreme Court opinions, and Wex, a plain-language legal encyclopedia, all at stable, well-structured URLs. That combination of authority, permanence, and clean markup is why law.cornell.edu shows up so often when a search engine or an AI system needs to point at what a statute actually says.

A firm will not outrank LII for "what is 42 U.S.C. 1983". It should not try. The opportunity is to stand on LII rather than compete with it. When a practice-area page explains a statute, it should quote the operative language and link to the primary text on LII or the official state legislature site. That linking does three things: it makes the page verifiable for a reader, it shows a reviewer that the claims are grounded, and it gives an AI engine a page that both explains the law and cites it, which is a stronger candidate for a grounded answer than a page that only paraphrases.

We treat outbound links to primary legal sources as a quality signal in the audit and flag practice-area pages that state legal rules with no source at all.
