Blue Book

A publication that establishes the correct form of case citations or of references to a legal authority showing where information can be found. A volume that explains the organization of a state government and provides the names of state officials. The proper title is "The Bluebook: A Uniform System of Citation." In a generic sense, this term also refers to a report issued by the Joint Committee on Taxation regarding recent tax legislation.

The Blue Book is published by the Harvard Law Review Association in conjunction with law review journals in Yale University, Columbia University, and the University of Pennsylvania. It has been the preeminent authority on proper citation form for more than 70 years.
