The Bluebook, formally titled The Bluebook: A Uniform System of Citation, is the style manual for citing to legal documents within the United States. The Bluebook is compiled by the editors of the Columbia Law Review, the Harvard Law Review, the University of Pennsylvania Law Review, and The Yale Law Journal.
The Law Library has 4 copies of the current edition on reserve (and several of the previous edition in the Law Library Stacks). These can be checked out from the Circulation Desk for in-library use.
User's Guide to The Bluebook (Alan L. Dworsky)
This pamphlet, revised for the 21st Edition of The Bluebook, provides plain language interpretations of citation rules for practitioners (from the Bluepages) such as when and when not to underline words. It provides a brief overview of the rules in general, and goes into depth on commonly cited documents such as cases and statutes.
