A consistent and uniform citation method for legal materials is important for two reasons. First, it must be possible for the reader to accurately and efficiently locate and verify the information that is offered in support of legal arguments and theories. Second, a citation system provides visual clues to the reader as to the authority of the referenced legal material.
The two most often used citation systems in the United States are The Bluebook: A Uniform System of Citation and the ALWD Guide to Legal Citation.
Peter W. Martin created the free online resource Introduction to Basic Legal Citation. This resource is indexed to the fourth edition of the ALWD Guide to Legal Citation and the 19th edition of The Bluebook. Martin's introduction notes that the resource "also documents the many respects in which contemporary legal writing, very often following guidelines set out in court rules, diverges from the citation formats specified by those academic texts." Short tutorials and other examples are provided to help the user understand and apply the citation systems.
Another interactive online free resource was created by the Georgetown University Law Library. There is a general BlueBook Guide and three short interactive video tutorials that address citations for cases, statutes, and law review articles.
