Bluebook Citation 101 -- Practitioner Format

The Bluebook: A Uniform System of Citation is generally the default legal citation manual. It 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 and began in 1926. It is now in its 21st edition. Other general legal citation manuals include ALWD, and The Redbook. Additionally, each jurisdiction and court may have its own citation rules. Ohio, for example, has its own writing manual.

User's Guide to the "Bluebook" by Alan L. Dworsky; David Tomenes Written for practitioners, the User's Guide covers the major Bluebook rules and most commonly cited materials.

Learning legal citation is one of the difficult (and sometimes admittedly annoying) tasks that students new to the law face. This book is designed to ease that task. It initially focuses on conventions that underlie all accepted forms and systems of legal citation. Building on that understanding and an explanation of the process of using citations in legal writing, the book then discusses and illustrates the particular rules of The Bluebook and the ALWD Citation Guide for citing cases, statutes, and all other major legal sources. Its unique appendices provide a useful reference resource to aid students in formulating citations.

Introduction to Basic Legal Citation This publication is indexed to both ALWD and Bluebook citation manuals. The content of this guide is also available in three different e-book formats: 1) a pdf version; 2) a version designed specifically for use on the full range of Kindles as well as other readers or apps using the Mobi format; and 3) a version in ePub format.

The Indigo Book is a free, Creative Commons-dedicated implementation of The Bluebook’s Uniform System of Citation. The Indigo Book was compiled by a team of students at the New York University School of Law, working under the direction of Professor Christopher Jon Sprigman. The scope is comparable to the Bluepages in The Bluebook.

          Signals

          Overview

          Rule 1.2 of The Bluebook (21st ed. 2020) covers the use of signals. Signals are used in front of citations to alert the reader as to how that citation is being used. They can be quite confusing!

          Do not use a signal with a citation when you have directly borrowed someone else’s words or have paraphrased her words or ideas.

          Signals can also be used as verbs in text.

          Signals Used for Supportive Citations

          • E.g., – string cites, multiple examples but not an exhaustive list. Here are a few examples to illustrate /support my statement. You can combine this with other signals such as See.
          • Accord – 2 or more in agreement. The signal accord comes after another citation that supports the proposition. The first citation here directly supports the statement and the accord signal and second citation indicates another source that supports it. A common use of this signal is to show that two different jurisdictions agree.
          • See – clearly supports (obviously follows but not directly stated). Slightly less direct support than no signal.
          • See also – additional material supporting the proposition. Parenthetical explanation is encouraged.

          Signals Used for Comparative Citations

          • Cf. – compare (different but analogous – it doesn’t exactly support your statement but it is close). Parenthetical explanation encouraged.
          • Compare -- To actually compare two authorities directly. You must use “with,” and another citation with this signal. Parenthetical explanation encouraged.

          Signals Used for Contradictory Citations

          • Contra – directly states the contrary. The opposite of using no signal at all
