The Bluebook: A Uniform System of Citation, a style guide, prescribes the most widely used legal citation system in the United States. The Bluebookis compiled by the Harvard Law Review Association, the Columbia Law Review, the University of Pennsylvania Law Review, and the Yale Law Journal. 

The Bluebook is taught and used at a majority of U.S. law schools, and is also used in a majority of U.S. federal courts.
