How to Format Legal Citations Correctly
Cases, statutes, law review articles, books, and websites — with the practitioner vs. law review format distinction, pincites, signals, short forms, and the errors that lose marks in legal writing courses explained source type by source type.
The Bluebook trips up most 1Ls in the same way. It is not that the rules are impossible — it is that there are two completely different formats inside the same book, and students frequently mix them without realising it. Use the wrong one for your assignment type and every citation is wrong by default, regardless of how carefully you formatted each one. This guide walks through what the Bluebook actually requires, source type by source type, format by format.
What This Guide Covers
What the Bluebook Is and Who Uses It
The Bluebook: A Uniform System of Citation is published by the Harvard Law Review Association, with editorial collaboration from the Columbia Law Review, the University of Pennsylvania Law Review, and the Yale Law Journal. The 21st edition (2020) is current. It is the dominant legal citation system in the United States, used across law schools, law reviews, courts, and legal practice.
That said, it is not universal. Some courts have their own local citation rules that override or supplement the Bluebook. Some jurisdictions prefer practitioner-developed guides. Some law schools teach the ALWD Guide to Legal Citation as an alternative — it is simpler to navigate and produces nearly identical results. Before you assume Bluebook is what your professor wants, check the assignment brief.
Who It’s Designed For
Law students, law review editors, legal scholars, and legal practitioners. The Bluepages (the blue-edged pages at the front) are specifically for practitioners — attorneys writing briefs, memos, and court documents. The white pages cover academic legal writing for law review articles and seminar papers.
The 21st Edition — What Changed
The 21st edition (2020) introduced updated rules for online sources, electronic databases, and URLs. It also clarified rules for social media citations and updated abbreviation tables. If your professor references a specific edition, use that one — rules do change between editions.
Bluebook vs. ALWD — Quick Comparison
Both systems produce nearly identical citation formats for most source types. The main differences are in the organisation of rules, some abbreviation choices, and the treatment of certain secondary sources. If your program uses ALWD, do not apply Bluebook rules — they differ in details that matter.
The Bluebook is published by the Harvard Law Review Association and is available in print and online. The official digital version is accessible at legalbluebook.com — most law school libraries provide institutional access. The ALWD Guide to Legal Citation (Association of Legal Writing Directors) is available at alwd.org. For a free quick-reference, Georgetown Law Library maintains one of the most accurate publicly available Bluebook guides at guides.ll.georgetown.edu/bluebook.
The Two Formats — Practitioner vs. Law Review
This is the thing most students get wrong first. The Bluebook contains two separate citation systems inside the same book. Using the wrong one for your document type means every citation is formatted incorrectly — even if each individual element is right.
Practitioner Format (Bluepages)
- Used for: legal memos, briefs, court documents, client letters
- Citations appear in the body text, not footnotes
- Case names: italicised in running text, not underlined
- No large and small capitals — plain roman type for most elements
- Signals still used, but less frequently than in academic writing
- Short forms and id. operate the same way
- This is what most 1L legal writing courses use for memos and briefs
Law Review Format (White Pages)
- Used for: law review articles, seminar papers, academic notes
- Citations appear in footnotes — not in the text body
- Author names: ordinary roman type
- Book and journal titles: large and small capitals (e.g. Legal Writing)
- Article titles: italicised
- Signals used extensively to characterise authority
- This is what law review editors and seminar paper writers use
A brief gets practitioner format. A law review note or seminar paper gets law review format. If your professor says “use the Bluebook” without specifying which format, ask. Submitting a memo with footnotes, or a law review note with in-text citations, is a formatting error that affects every citation in the document. It signals to your professor that you have not read the Bluepages or do not understand the distinction.
Case Citations — Full and Short Forms
Case citations are the backbone of legal writing. Get the anatomy right and the variations follow logically.
Case Name — Italicised, Abbreviated
In practitioner format, the case name is italicised in both full and short citations. Use only the first-listed party on each side — so Brown v. Board of Education, not Brown et al. v. Board of Education of Topeka, Kansas et al. The Bluebook’s Table T6 provides abbreviations for commonly abbreviated words in case names (e.g., “Department” becomes “Dep’t”).
Volume Number, Reporter Abbreviation, First Page
The volume number comes first, then the abbreviated reporter name (Table T1 covers federal and state reporters), then the first page of the case. No comma between the reporter and the page number. Example: 347 U.S. 483. “U.S.” is the United States Reports — the official reporter for Supreme Court decisions. “S. Ct.” is the Supreme Court Reporter (West); “L. Ed.” is Lawyers’ Edition.
Pincite — Required for Specific Propositions
When you are citing a specific holding, passage, or proposition, add the pinpoint page after a comma following the first page. Brown v. Board of Education, 347 U.S. 483, 495 (1954). The pincite is 495. Omitting the pincite when you are drawing on a specific page is technically incomplete — it forces the reader to search the whole case for what you are citing.
Parenthetical — Court and Year
The parenthetical at the end contains the court abbreviation and year. For U.S. Supreme Court cases cited in the U.S. Reports, no court abbreviation is needed — (1954) is sufficient. For lower federal courts and state courts, include the court abbreviation: (5th Cir. 2021) or (Cal. Ct. App. 2020). Table T1 and T7 cover court abbreviations. If the court is obvious from the reporter, it may be omitted.
| Court | Reporter(s) | Abbreviation | Court in Parenthetical? |
|---|---|---|---|
| U.S. Supreme Court | United States Reports (official) | U.S. |
No — omitted when citing U.S. Reports |
| U.S. Supreme Court | Supreme Court Reporter (West) | S. Ct. |
No — court clear from reporter |
| Federal Circuit Court | Federal Reporter (West) | F.2d, F.3d, F.4th |
Yes — e.g. (2d Cir. 2021) |
| Federal District Court | Federal Supplement (West) | F. Supp., F. Supp. 2d, F. Supp. 3d |
Yes — e.g. (S.D.N.Y. 2020) |
| State Supreme Courts | Varies by state | See Table T1 | Depends on reporter — check T1 |
| Westlaw / Lexis (no print reporter) | Use database citation | WL [number] or LEXIS [number] |
Yes — always include court |
Federal and State Statute Citations
Statutes are cited to their codified location whenever possible. The U.S. Code is the codified version of federal law. If a statute has not yet been codified, cite it to the Statutes at Large.
Codified Federal Statutes — U.S. Code
Format: Name of Act (if commonly known), Title U.S.C. § section(s) (Year of code edition).
Example: Americans with Disabilities Act of 1990, 42 U.S.C. §§ 12101–12213 (2018).
The year is the edition of the U.S. Code, not the enactment date. Use § for a single section, §§ for multiple. A space between § and the number.
Uncodified Statutes — Statutes at Large
Format: Name of Act, Pub. L. No. congress-number, stat. first-page (year enacted).
Example: Dodd-Frank Wall Street Reform and Consumer Protection Act, Pub. L. No. 111-203, 124 Stat. 1376 (2010).
Use this format when a law has not been incorporated into the U.S. Code or when you need to cite a specific provision as enacted rather than as codified.
Law Review Articles and Journals
Law review citations differ in structure depending on which format you are using. In practitioner format, they rarely appear — secondary sources are less common in briefs than in academic writing. In law review format, they appear constantly. Either way, the anatomy is the same.
Author Name
Full name, as it appears on the article. In practitioner format: plain roman type. In law review format: plain roman type for author names (unlike books, which use large and small capitals for the author in some editions).
Article Title
Italicised in both formats. Sentence case is not required — follow the article’s own title casing. No quotation marks around article titles in Bluebook (unlike Harvard referencing).
Volume, Journal, First Page
Volume number, then journal abbreviation (Table T13), then first page. No comma between journal abbreviation and first page. In law review format, journal name in large and small capitals: Harv. L. Rev.
Pincite
Specific page after a comma, following the first page. Always include when citing a specific argument or passage. Omitting it when you are drawing on a particular page is an incomplete citation.
Year in Parentheses
Year the article was published, in parentheses at the end. That is the full citation. Clean and straightforward once you have the journal abbreviation right.
Journal Abbreviations
Table T13 in the Bluebook covers journal name abbreviations. Getting these wrong is common. “Harvard Law Review” is not “Harv. L.R.” — it is “Harv. L. Rev.” Check T13 for every journal name you abbreviate.
Books, Treatises, and Secondary Sources
Books and treatises are cited differently from cases and statutes. In law review format, author names and title appear in large and small capitals — that formatting signals to the reader it is a secondary source, not primary authority.
Practitioner Format
Bryan A. Garner, The Elements of Legal Style 42 (2d ed. 2002). — Author’s full name, italicised title, pincite page in parentheses before the edition and year.
Large and Small Capitals for Author and Title
Bryan A. Garner, The Elements of Legal Style 42 (2d ed. 2002). — Same information, different typography. Both author and title appear in large and small capitals in law review format.
Multi-Volume Works
4 Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure § 1067 (3d ed. 2002). — Volume number precedes the author name for multi-volume works. Section symbol for section citations instead of a page number.
Chapter in an Edited Volume
Guido Calabresi, The Pointlessness of Pareto: Carrying Coase Further, in Essays in Honor of Guido Calabresi 49, 55 (John Witt ed., 2011). — Chapter author and italicised chapter title, then “in” followed by book title in large and small caps, first page, pincite, editor, and year.
Restatements and model codes have their own citation format. Restatement (Third) of Torts: Products Liability § 2 (Am. L. Inst. 1998). The American Law Institute publishes restatements. The Model Penal Code and other model codes follow a similar pattern. These are treated as authoritative secondary sources, not primary authority — they do not have binding legal effect unless adopted by a jurisdiction.
Websites and Online Sources
The Bluebook’s treatment of online sources is more nuanced than most students expect. The preference is always for a permanent, stable citation — a print reporter, an official code, a DOI. A URL is a last resort, not a first choice, because URLs break.
If a source exists in print or in a stable electronic database (Westlaw, LexisNexis, Bloomberg Law), cite that version. Use a URL only when no other source is available. Legal databases are not cited with a URL — use the database name and the document identifier: Brown v. Board of Education, 347 U.S. 483 (1954), available in Westlaw at 1954 WL 47878.
Author (if identifiable), Title of Page, Website Name, URL (date of publication or last update; last visited date). Example: Adam Liptak, Supreme Court Ruling Makes Same-Sex Marriage a Right Nationwide, N.Y. Times, https://www.nytimes.com/… (June 26, 2015). When no publication date is available, include only the last-visited date.
For government agency websites and official publications posted online, the citation format mirrors print government documents but adds the URL and a last-visited date. Executive Order No. 14,067, 87 Fed. Reg. 14,143 (Mar. 14, 2022), https://www.federalregister.gov/documents/2022/03/14/… Executive Orders are cited to the Federal Register.
Citation Signals — When and How to Use Them
Signals tell the reader how the cited authority relates to the proposition in your text. They are not decorative. Using no signal when “see” is correct, or using “see” when the source directly states the proposition, are both errors that signal to your professor you have not learned signal usage.
| Signal | When to Use It | Example Situation |
|---|---|---|
| [no signal] | The cited source directly states the proposition you are making, or is the source you are quoting. | You quote a case holding. You cite the statute that directly creates the rule you are describing. |
| See | The source supports the proposition but does not directly state it — support is clear from the source but requires inference. | The case’s reasoning supports your argument, but it does not say your precise proposition in so many words. |
| See also | Additional supporting authority, used when primary support is already cited. | You have already cited the leading case; this is additional circuit authority that reaches the same result. |
| Cf. | The source supports the proposition by analogy — the cited authority involves a different but related situation. | A Fourth Amendment case that provides reasoning applicable to a First Amendment argument by analogy. |
| Compare . . . with | Comparison of two authorities to illuminate a conflict, tension, or distinction. | Two circuit courts reaching different results on the same statutory interpretation question. |
| But see | The source directly contradicts your proposition but is clearly contrary authority. | A circuit court case reaching the opposite result from the one you are arguing. |
| Contra | The source directly and squarely contradicts the proposition. | A case or statute that states the opposite of your proposition. |
| See generally | Background or general support — the source provides helpful context but is not directly on point. | A law review article providing a useful overview of the area of law you are discussing. |
All signals are italicised in Bluebook format: See, see also, cf., but see, contra, see generally. The only exception is when no signal is used — the absence of a signal is itself significant, indicating the source directly states the proposition. Do not italicise “id.” — it is not a signal, it is a short form citation tool.
Short Forms, Id., and Supra
Once you have given a full citation, you do not repeat it in full every time. You use a short form. There are three main tools: id., supra, and a shortened case name with “at.” Getting these right saves space and makes legal writing read cleanly. Getting them wrong is a consistent 1L error.
Immediately Preceding Citation — Same Source
Use Id. only when the immediately preceding citation (with no intervening citations to any other source) is to the same source. Id. at 495 — to a different page of the same source. Id. alone — to the exact same page. If any other citation intervenes, you cannot use id. You must use a case short form or supra instead.
Previously Cited Secondary Source — Not Cases or Statutes
Supra is used to refer back to a previously cited secondary source (book, law review article) that is not the immediately preceding citation. Format: Author, supra note [footnote number], at [page]. Do not use supra for cases or statutes — use the short form case citation instead.
Previously Cited Case — Shortened Name + “at”
Use one party’s name (usually the first-listed party or the more distinctive name), then the volume reporter “at” and the pincite. Brown, 347 U.S. at 495. Do not use supra for cases. The short form case citation is always used after the first full citation when id. does not apply.
Forward Reference — Used Sparingly
Infra refers to a source that will be fully cited later in the document. It is used much less frequently than supra. Format: Author, infra note [footnote number]. It signals to the reader that the full citation is coming — useful in introductory footnotes that preview later discussion.
Wrong — Using Id. After an Intervening Citation
Footnote 5: Brown v. Board of Education, 347 U.S. 483, 495 (1954).
Footnote 6: Marbury v. Madison, 5 U.S. 137, 177 (1803).
Footnote 7: Id. at 497.
Footnote 7’s id. refers to the immediately preceding citation — which is Marbury, not Brown. If you mean Brown, you must use the short form: Brown, 347 U.S. at 497.
Correct — Short Form When Citation Is Not Immediately Preceding
Footnote 5: Brown v. Board of Education, 347 U.S. 483, 495 (1954).
Footnote 6: Marbury v. Madison, 5 U.S. 137, 177 (1803).
Footnote 7: Brown, 347 U.S. at 497.
The short form case citation correctly points back to Brown without the ambiguity that id. would create after an intervening citation.
Pincites and Parallel Citations
A pincite is not optional when you are drawing on a specific passage. It tells the reader exactly where in the source to find what you are citing. “See Brown v. Board of Education, 347 U.S. 483 (1954)” for a specific quote from page 495 of that case is an incomplete citation. The reader has to search a 16-page opinion for the passage you mean.
When Pincites Are Required
Any time you quote directly from a source. Any time you cite a specific holding, finding, or proposition from a particular page. Any time you are drawing on an argument that appears on specific pages of an article or book.
Pincites are not required when you are citing the case for its general holding and the holding is stated on the first page, or when you are simply noting the existence of a case without drawing on any specific passage from it.
Parallel Citations
Some jurisdictions require parallel citations — citing a case in both the official reporter and a commercial reporter (West). Example: Palsgraf v. Long Island Railroad Co., 248 N.Y. 339, 162 N.E. 99 (1928) — the official New York Reports and the North Eastern Reporter.
Federal courts do not require parallel citations for U.S. Supreme Court cases in most contexts. State court rules vary significantly — check the local rules for the jurisdiction you are writing about.
Common Errors That Cost Marks
Using Law Review Format for a Brief or Memo
Putting citations in footnotes in a legal memo. Using large and small capitals in a brief. This signals that you have not identified which Bluebook format applies to your assignment type — a fundamental error, not a formatting slip.
Match Format to Document Type — Every Time
Practitioner format for briefs and memos: citations in text, no large and small caps. Law review format for seminar papers and law review notes: citations in footnotes, large and small caps for book/journal titles. Confirm which format applies before you write a single citation.
Using Id. After an Intervening Citation
Id. refers to the immediately preceding citation only. If any other citation appears between your current citation and the one you are short-forming, id. is wrong. It now refers to the wrong source. This is the most common short-form error in 1L writing.
Check What Immediately Precedes Before Using Id.
Before writing id., look at the citation immediately before. Is it to the same source? If not, use a short form case citation (Brown, 347 U.S. at 495) or author supra note X, at page. When in doubt, use the short form — it is always safer than a misapplied id.
Comma Between Reporter and First Page
Brown v. Board of Education, 347 U.S., 483 (1954) is wrong. There is no comma between the reporter abbreviation and the first page number of a case citation. This appears in hundreds of 1L papers every year.
No Comma Between Reporter and Page
347 U.S. 483 — volume, reporter, page. No comma between “U.S.” and “483”. The comma in a case citation separates the case name from the volume number, and the first page from the pincite. Not the reporter from the page.
No Space Between § and Section Number
42 U.S.C. §12101 is wrong. The Bluebook requires a space between the section symbol and the number: § 12101. Missing the space is a minor error that nonetheless shows inattention to formatting requirements.
§ [space] Number — Always
42 U.S.C. § 12101. One space between § and the section number. Use §§ (with a space) for multiple sections: 42 U.S.C. §§ 12101–12213. The same applies to paragraph symbols: ¶ 4, not ¶4.
Wrong Year for Statute — Using Enactment Date
42 U.S.C. § 12101 (1990) — wrong. The year in parentheses for a codified statute is the edition year of the U.S. Code, not when the statute was enacted. The ADA was enacted in 1990, but the current U.S. Code edition is 2018.
Use the Code Edition Year, Not the Enactment Year
42 U.S.C. § 12101 (2018) — correct. The year is the edition of the code you consulted. For Westlaw and Lexis, they display the current year of the code version. Use that year, not when Congress passed the law.
Supra for Cases
Using “Smith supra note 3″ to short-form a case citation. Supra is for secondary sources — books and law review articles. It is not used for cases or statutes, which have their own short form citation formats.
Short Form Case Citation for Cases — Not Supra
For cases: Brown, 347 U.S. at 495. For statutes: 42 U.S.C. § 12101. For law review articles and books: Author, supra note X, at page. Each source type has its own short form. Using supra for a case citation is a consistent Bluebook error.
Quotation Marks Around Article Titles
Putting article titles in quotation marks: Richard Posner, “The Law and Economics of Intellectual Property.” That is Harvard referencing convention — single quotation marks around article titles. Bluebook italicises article titles. No quotation marks.
Italics for Article Titles in Bluebook
Richard Posner, The Law and Economics of Intellectual Property. Article titles are italicised. Journal names are either plain (practitioner format) or in large and small capitals (law review format). No quotation marks appear in Bluebook article citations.
Missing Court Designation for Lower Court Cases
United States v. Carroll Towing Co., 159 F.2d 169 (1947) — missing the court abbreviation. For federal circuit and district court cases, the court must be identified inside the parenthetical.
Always Include Court for Non-Supreme Court Federal Cases
United States v. Carroll Towing Co., 159 F.2d 169, 173 (2d Cir. 1947). The “(2d Cir.)” tells the reader this is a Second Circuit Court of Appeals decision. Without it, the reader knows it is a federal circuit case (from F.2d) but not which circuit. Check Table T1 for all court abbreviations.

Legal Writing Taking More Time Than the Law Itself?

Academic Writing Services Get StartedWhat Getting Bluebook Right Actually Takes
Most Bluebook errors are not random. They cluster around the same handful of rules — id. after intervening citations, the wrong year for statutes, missing court designations, mixing practitioner and law review format. None of them are hard to fix once you know the rule. The problem is usually that students learned Bluebook by example rather than by reading the actual rules.
Three things will prevent most errors. First, read the Bluepages before writing your first memo — not your professor’s handout, the actual Bluepages. They are 40 pages. They tell you exactly what practitioner format requires. Second, check Table T1 for every case reporter abbreviation and Table T13 for every journal name abbreviation — do not guess. Third, before using id., look at the citation immediately before and confirm it is to the same source. If it is not, use the short form.
Citation generators and AI tools get Bluebook wrong regularly. They do not know whether you are writing a brief or a seminar paper. They do not check whether the preceding citation is to the same source. They do not distinguish between the code edition year and the enactment year. Use them to draft, then check every citation yourself against the Bluebook or a verified guide like Georgetown Law Library’s.
