Bluebook Abbreviations: Legal Citation Rules

Bluebook abbreviations are standardized shorthand contractions prescribed by The Bluebook: A Uniform System of Citation to compress legal case names, statutory reporters, judicial tribunals, geographic jurisdictions, and academic periodicals into compact citation formats. Within academic legal scholarship, student-edited law reviews, and the discipline of legal studies, applying correct abbreviations is essential for ensuring bibliographic precision, maintaining editorial uniformity, and conserving typographical space in complex footnotes.

The format

In standard Bluebook citation practice, abbreviations operate under a strict dual regime governed by Rule 10.2: the rules applied within running narrative text (Rule 10.2.1) differ substantially from those applied within citation sentences, citation clauses, and footnotes (Rule 10.2.2). The general template for a standard American judicial citation follows this sequence:

[Abbreviated Case Name], [Volume Number] [Abbreviated Reporter] [First Page], [Pincite] ([Abbreviated Deciding Court] [Year of Decision]).

Each component requires specific abbreviation tables defined in the Bluebook:

• Case Name: Formatted using Table T6 (Case Names and Institutional Authors in Citations) and Table T10 (Geographical Terms). In citation clauses and footnotes, every word listed in Table T6 must be abbreviated. In textual narrative sentences, only eight specified business terms and widely recognized acronyms are abbreviated.
• Reporter Name: Abbreviated according to Table T1 (United States Jurisdictions). Repetitive words and series numbers follow strict spacing rules (for example, closed spacing between adjacent single capitals like F.3d or S. Ct.).
• Deciding Court: Formatted using Table T1 and Table T7 (Court Names), omitting jurisdictional redundancies when the reporter uniquely identifies the court (such as omitting “U.S.” when citing the official U.S. Reports).
• Periodicals and Journals: When citing secondary scholarship, law review titles are abbreviated using Table T13 (Periodicals), which combines standard institutional abbreviations (e.g., Harv. L. Rev., Yale L.J., Colum. L. Rev.).

Examples

The following examples illustrate standard Bluebook abbreviation mechanics across different legal authorities and citation contexts. Illustrative party names are composites designed to demonstrate specific table applications:

1. Standard Federal Appellate Case (Citation Sentence):
   Nat’l Env’t Prot. Ass’n v. Midwest Transp. Corp., 985 F.3d 412, 418 (7th Cir. 2021).
   Explanation: In the citation sentence, “National” becomes “Nat’l”, “Environmental” becomes “Env’t”, “Protection” becomes “Prot.”, “Association” becomes “Ass’n”, “Transportation” becomes “Transp.”, and “Corporation” becomes “Corp.” pursuant to Table T6. The Federal Reporter Third Series is abbreviated “F.3d”, and the Seventh Circuit is abbreviated “7th Cir.” pursuant to Table T1.
2. State Supreme Court Case with Table T10 Geographic Unit:
   Apex Chem. Mfg. Co. v. Commonwealth, 842 S.E.2d 110, 115 (Va. 2020).
   Explanation: “Chemical” becomes “Chem.”, “Manufacturing” becomes “Mfg.”, and “Company” becomes “Co.” under Table T6. The state jurisdiction Virginia is abbreviated “Va.” inside the parenthetical pursuant to Table T10.
3. Law Review Article Citation (Table T13):
   Jane R. Doe, Empirical Analysis of Appellate Citations, 134 Harv. L. Rev. 890, 895 (2021).
   Explanation: The author and article title are stated in full, while the journal title is compressed into standard Table T13 components: “Harvard” becomes “Harv.”, “Law” becomes “L.”, and “Review” becomes “Rev.”
4. Secondary Authority Citation to Restatements:
   Restatement (Third) of Torts: Liab. for Physical & Emotional Harm § 7 (Am. L. Inst. 2010).
   Explanation: Citations to secondary authorities like Restatements of the Law abbreviate “Liability” to “Liab.”, “American” to “Am.”, “Law” to “L.”, and “Institute” to “Inst.” pursuant to Table T6.

In-text citation version

A frequent trap in legal research and writing occurs when citing authorities within a narrative textual sentence. Under Bluebook Rule 10.2.1(c), case names embedded in running prose must be spelled out, subject to only two exceptions:

• Widely Recognized Acronyms: Well-known agency abbreviations without periods (such as FBI, SEC, FCC, EPA, or NLRB) are permitted in running text.
• Eight Permitted Business Designations: Only the following eight words may be abbreviated in narrative text:
  1. & (ampersand)
  2. Ass’n (Association)
  3. Bros. (Brothers)
  4. Co. (Company)
  5. Corp. (Corporation)
  6. Inc. (Incorporated)
  7. Ltd. (Limited)
  8. No. (Number)

The First-Word Prohibition: Crucially, under Rule 10.2.1(c), none of these eight business designations may be abbreviated if it forms the very first word of a party’s name. For example, if a lawsuit is brought by “Company of Global Merchants”, the word “Company” must be written out in full when appearing in a narrative sentence: Company of Global Merchants v. Davis.

Contrast Example:

• In-Text Narrative Sentence (Rule 10.2.1): “In National Environmental Protection Association v. Midwest Transportation Corp., the Seventh Circuit clarified the statutory compliance standard.”
• Citation Clause / Footnote (Rule 10.2.2 & Table T6): “The Seventh Circuit clarified the statutory compliance standard, Nat’l Env’t Prot. Ass’n v. Midwest Transp. Corp., 985 F.3d 412, 418 (7th Cir. 2021).”

Common errors

Authors and researchers preparing law review submissions under law review authorship standards frequently encounter specific abbreviation errors:

• Over-Abbreviating Narrative Text: Applying Table T6 contractions (such as “Univ.”, “Hosp.”, “Elec.”, or “Telecomm.”) inside narrative body sentences where Rule 10.2.1 requires them to be spelled out in full.
• Spacing Mistakes in Reporter Names: Failing to apply Rule 6.1 regarding adjacent single capitals. Close the space between consecutive single capitals (F.3d, N.E.2d, S.W.3d), but insert a space before or after any abbreviation containing more than one letter or a number (F. Supp. 3d, Cal. App. 4th, So. 3d).
• Abbreviating “United States” Incorrectly: Under Rule 10.2.2, when the United States is a named party to a case, it is never abbreviated as “U.S.” in the case name caption; it must be written out in full as United States (e.g., United States v. Miller). However, when used as an adjective or geographic unit (such as in a statutory title or court reporter), “U.S.” is correct.
• Abbreviating First Words in Case Names: In narrative sentences, abbreviating the first word of a party’s name even if it is one of the eight permitted business terms.
• Omitting Pincites in Scholarly Manuscripts: Failing to pinpoint specific page numbers when citing quotes, rules, or holdings, which hinders verification in open repositories like CourtListener.

Style-guide edition

The rules and abbreviation tables outlined in this guide reflect The Bluebook: A Uniform System of Citation, Twenty-First Edition (2020), compiled and published jointly by the editorial boards of the Columbia Law Review, the Harvard Law Review, the University of Pennsylvania Law Review, and the Yale Law Journal. While older editions (such as the Twentieth Edition, 2015) remain widely referenced in historical citations, the Twenty-First Edition governs current academic law reviews, judicial clerkship submissions, and legal memoranda.

FAQ

What is Table T6 in the Bluebook?

Table T6 is the primary abbreviation table in the Bluebook governing case names and institutional authors in citations. It contains hundreds of standardized abbreviations for commonly recurring words (such as “Department” to “Dep’t”, “International” to “Int’l”, and “Hospital” to “Hosp.”) that must be applied when a case name appears in a citation sentence, citation clause, or footnote.

What is the difference between Bluebook Rule 10.2.1 and Rule 10.2.2?

Rule 10.2.1 governs case names appearing in running narrative text, requiring most words to be spelled out in full except for widely known acronyms and eight specific business designations. Rule 10.2.2 governs case names appearing in citation sentences, citation clauses, and footnotes, requiring comprehensive abbreviation of all words listed in Table T6.

How do you abbreviate law reviews in Bluebook?

Law reviews and legal periodicals are abbreviated using Table T13 in the Bluebook. Individual words in the journal’s name are replaced with their Table T13 abbreviations (such as “Harvard” to “Harv.”, “Columbia” to “Colum.”, “Law” to “L.”, and “Review” to “Rev.”), resulting in standardized abbreviations like Harv. L. Rev. or Yale L.J.

Can you abbreviate eight-letter words not in Table T6?

Yes. Under Bluebook Rule 10.2.2, authors have discretion in citation clauses and footnotes to abbreviate any word of eight letters or more that does not appear in Table T6, provided the abbreviation saves substantial space, is intuitively understandable, and does not create ambiguity for the reader.
