The Undergraduate Guide to Bluebook Citations

What is the Bluebook?

The Bluebook: A Uniform System of Citation is a standardized guide to citing legal authorities in the United States. It establishes conventions for identifying court decisions, statutes, constitutional provisions, administrative regulations, academic publications, and other sources.

The current edition is the 22nd edition, published in 2025.

Legal citations serve three essential purposes:

• Verification: Allow readers to locate and examine the sources supporting an argument.
• Credibility: Demonstrate that legal conclusions are grounded in identifiable authority.
• Clarity: Communicate precisely which decision, statutory provision, or scholarly work supports a statement.

Unlike APA or MLA, legal citation uses specialized conventions that identify courts, reporters, jurisdictions, and legal authorities.

Bluepages and Whitepages

The Bluebook distinguishes between citation conventions used in legal practice and those used in academic legal scholarship.

Bluepages: Primarily intended for legal practitioners preparing briefs, memoranda, and other legal documents.

Whitepages: Primarily intended for academic legal writing, including law review articles and student notes.

Court decisions are among the most important sources in legal scholarship.

A standard published judicial opinion citation identifies the case name, the reporter containing the decision, its starting page, and the year of the decision. Depending on the court and reporter, additional court information may be required.

Example: United States Supreme Court

Citing a specific page

When referring to a particular passage or proposition, provide a pinpoint citation.

The additional page number directs the reader to page 495 of the decision.

Additional examples

Statutes are laws enacted by legislative bodies. Federal statutes are commonly cited to the United States Code, while state statutes are cited to their respective state compilations.

Example: Federal statute

The citation identifies the federal law commonly used in civil rights litigation involving individuals acting under color of state law.

Additional example

This citation identifies a section of the Fair Labor Standards Act concerning minimum wages.

State statutes

State legislatures organize and publish their laws differently. Citations may require a state-specific abbreviation, chapter, section, and publication year.

Consult the appropriate Bluebook jurisdictional rules when citing state law.

Constitutional citations identify the relevant constitution and the specific article, amendment, or section.

Examples

These examples refer to the First Amendment, Section 1 of the Fourteenth Amendment, and the Commerce Clause.

Important distinction

A constitutional provision and a court opinion interpreting that provision are different legal authorities.

When discussing constitutional text, cite the constitution. When discussing a judicial interpretation of that text, cite the relevant judicial opinion.

Often, a well-supported constitutional analysis will cite both.

Academic legal scholarship provides useful background, interpretations of cases, competing arguments, and proposals for legal reform.

A law review citation generally identifies the author, article title, journal, volume, beginning page, relevant pinpoint page when applicable, and publication year.

Example

This is an influential article examining legal protections for personal privacy.

When should you cite scholarship?

Use academic articles to identify important debates, contextualize doctrine, and engage with arguments developed by other scholars.

However, when making a claim about what a court held or what a statute requires, consult and cite the underlying primary legal authority whenever possible.

Legal scholarship increasingly depends on government databases, public reports, institutional publications, and online information.

A website citation should provide sufficient identifying information for a reader to locate the cited material.

Depending on the source, relevant information may include:

• Author or publishing organization
• Title of the webpage or publication
• Date of publication or update
• URL
• Archived version or preserved copy

The Bluebook's 22nd edition includes substantially revised rules addressing electronic sources, online materials, and AI-generated content.

Example: Government report

Suppose you are citing a report published online by a federal agency.

Identify the agency, report title, publication date, and appropriate URL. Then check the relevant Bluebook rule to determine the final formatting and whether additional archival information is necessary.

Preserve your sources

Webpages can change or disappear.

When relying on online materials, save a copy or use a reputable archival service, such as Perma.cc, where appropriate.

NULR authors should preserve materials supporting important factual and legal claims so that editors can verify them.

Academic legal writing generally uses footnotes to identify the authorities supporting assertions in the main text.

A footnote may contain a single citation, several citations, or additional explanatory material.

Full citations

The first reference to an authority generally uses a complete citation.

Short-form citations

When returning to a previously cited authority, a shortened citation may be appropriate under the applicable Bluebook rules.

Using Id.

The abbreviation Id. refers to the immediately preceding cited authority when the Bluebook's conditions for its use are satisfied.

For a different pinpoint page, an appropriately formatted citation may read:

Even experienced legal writers make citation errors. Before submitting an academic paper, review these common problems.

1. 1. Missing pinpoint citations
   A citation to an entire judicial opinion may not adequately identify the passage supporting a specific proposition.
2. 2. Incorrect reporter abbreviations
   A court's jurisdiction and reporter affect the required citation format.
3. 3. Inconsistent case-name formatting
   Case names may require standardized abbreviations and distinctive typography.
4. 4. Incomplete online citations
   Links alone may not provide sufficient information to identify and preserve a source.
5. 5. Incorrect use of Id. or short forms
   Always verify that the reader can determine exactly which authority is referenced.
6. 6. Relying exclusively on secondary summaries
   When analyzing a judicial holding or statutory provision, examine the actual legal authority.
7. 7. Failing to verify generated citations
   AI tools and automated citation generators can produce nonexistent cases, incorrect page numbers, or inaccurate quotations. Check every citation against its original source.

The National Undergraduate Law Review publishes original legal scholarship written by undergraduate students.

Authors should follow Bluebook citation conventions in footnotes, using the current edition of the manual.

We expect submissions to demonstrate good-faith adherence to legal citation standards. Students do not need to have mastered every Bluebook rule before submitting a note.

Our editorial process is intended to strengthen legal analysis, improve clarity, and help authors develop the conventions of professional legal scholarship.
