Frequently Asked Questions

What is Bluebook citation style?

The Bluebook: A Uniform System of Citation (21st edition) is the definitive citation guide for American legal writing. It is used in law reviews, court briefs, memoranda, and other legal documents. It provides rules for citing cases, statutes, books, articles, and other legal and non-legal sources.

What is the difference between Bluebook and OSCOLA?

Bluebook is the standard for US legal citation, while OSCOLA (Oxford Standard for the Citation of Legal Authorities) is used in UK law. Bluebook uses footnotes or embedded citations depending on the document type. OSCOLA always uses footnotes. Formatting rules for cases, statutes, and other sources differ significantly between the two systems.

How do I cite a case in Bluebook format?

Bluebook case citations include: Case Name (italicized), Volume Reporter Page (Court Year). Example: Marbury v. Madison, 5 U.S. (1 Cranch) 137 (1803). Include the court only if not obvious from the reporter abbreviation.

How do I cite a statute in Bluebook format?

Bluebook statute citations use: Title Code Section (Year). Example: 42 U.S.C. Section 1983 (2018). For state statutes, include the state code abbreviation. Use the official code when available.
