Bluebook vs. ALWD Citation Format: Key Differences Explained
Most law students learn the Bluebook, but about 100 law schools use the ALWD Guide to Legal Citation instead. The two systems are more alike than different, but the differences matter when you are switching between them or joining a law review that uses the other format.
What Is the ALWD Citation Manual?
The ALWD Guide to Legal Citation (pronounced "all-wood") is an alternative to the Bluebook published by the Association of Legal Writing Directors. It was first released in 2000, created by Professor Darby Dickerson (then at Stetson University College of Law), with the goal of providing a clearer, more accessible citation manual for law students.
Unlike the Bluebook, which is edited by law review editors from four Ivy League schools, the ALWD Guide is produced by legal writing professors who teach citation in the classroom every day. This difference in authorship shapes the manual's approach: the ALWD Guide tends to be more explicit in its explanations and includes more examples for each rule.
The current edition is the ALWD Guide to Legal Citation, 7th edition (2021). It dropped the word "Manual" from its name starting with the 6th edition and is now titled the "ALWD Guide."
History and Purpose of Each System
The Bluebook has been the dominant American legal citation system since 1926. It was originally created by the editors of the Harvard Law Review and has been jointly published by the law reviews of Harvard, Columbia, Penn, and Yale ever since. Its original purpose was to standardize citation in law review articles, and this academic origin continues to shape its structure. The Bluebook distinguishes between rules for academic writing (the main body) and rules for practitioner documents (the "Bluepages").
The ALWD Guide was created in response to frustrations with the Bluebook. Legal writing professors found the Bluebook difficult to teach because it was organized around law review conventions rather than the citation tasks students actually perform. The ALWD Guide was designed to be a teaching tool first: it uses a single set of rules for all legal documents, eliminating the Bluebook's confusing distinction between academic and practitioner formats.
Bluebook
First published 1926. Edited by law review editors. 21st edition (2020). Dual system (academic + practitioner).
ALWD Guide
First published 2000. Edited by legal writing professors. 7th edition (2021). Single unified system.
Key Differences with Side-by-Side Examples
For most citations, the Bluebook and ALWD produce identical results. The differences are in the details. Here are the areas where the two systems diverge:
The Bluebook uses two different typeface systems: one for law review footnotes (with large and small capitals, italics) and one for court documents and legal memoranda (no large and small capitals). The ALWD Guide uses a single typeface system for all documents.
Bluebook (law review style)
Book titles and legislative materials in LARGE AND SMALL CAPS
ALWD Guide
No large and small caps — uses ordinary type for all documents
Both systems italicize case names, but they differ slightly on abbreviations. The ALWD Guide generally tracks the Bluebook's abbreviation rules but includes some variations in its appendix tables.
Bluebook
Palsgraf v. Long Island R.R. Co.
ALWD Guide
Palsgraf v. Long Island R.R. Co.
In this example, the two systems produce the same result. Differences emerge in less common abbreviations.
The main difference in statute citations is the publisher parenthetical for unofficial codes. The ALWD Guide requires less information in the parenthetical for commonly cited codes.
Bluebook
Cal. Civ. Code § 1714 (West 2024).
ALWD Guide
Cal. Civ. Code § 1714 (2024).
Both systems use the same signals (see, see also, cf., contra, etc.), but the Bluebook italicizes all signals while some older ALWD editions did not italicize certain signals. The current ALWD 7th edition aligns with the Bluebook on signal formatting.
Bluebook
See Miranda v. Arizona, 384 U.S. 436 (1966).
ALWD Guide (7th ed.)
See Miranda v. Arizona, 384 U.S. 436 (1966).
The 7th edition now matches the Bluebook on signal italicization.
This is arguably the biggest practical difference. The Bluebook is organized by source type with a complex system of rules and tables. The ALWD Guide is organized more linearly, with numbered rules that follow the order in which elements appear in a citation. Many students and professors find the ALWD Guide easier to navigate.
Bluebook
Rules (R1–R21), Bluepages, Tables (T1–T16). Academic vs. practitioner split.
ALWD Guide
Parts 1–7, sequentially numbered rules. Single system for all document types.
Which Law Schools Use Which System
The vast majority of American law schools teach the Bluebook, but approximately 100 law schools use the ALWD Guide in their legal writing programs. The split is not based on school ranking or prestige — it is largely a function of the legal writing faculty's preference.
Schools that use the ALWD Guide in their legal writing courses still require students to learn the Bluebook if they join a law review or journal, because nearly all law reviews use the Bluebook. This means that if you learn ALWD first, you will likely need to learn the Bluebook later anyway.
Bluebook schools
Most T14 schools, most state flagship law schools, and the majority of ABA-accredited programs.
ALWD Guide schools
Approximately 100 schools, often with strong legal writing programs that prefer the ALWD's teaching-oriented approach.
Courts
Nearly all courts expect Bluebook citation format, though many have local rules that modify Bluebook conventions.
Practical Tips for Switching Between Systems
If you learned one system and need to use the other, the transition is straightforward because the two systems produce nearly identical citations in most cases. Focus on these areas where they diverge:
Check typeface conventions first
The Bluebook's large and small caps requirement for certain sources in law review format is the biggest adjustment. If you learned ALWD, study Bluebook Rule 2 on typeface.
Compare the abbreviation tables
Both systems have tables for abbreviations, but some entries differ. Bluebook Tables T6 and T10 correspond to ALWD Appendices 3 and 5.
Learn the Bluepages if you are switching to Bluebook
The Bluebook's Bluepages govern practitioner documents and have different rules from the main text. ALWD has no equivalent because it uses one system for everything.
Use the index
Both manuals have comprehensive indexes. When in doubt, look up the specific source type in the index rather than trying to navigate the rule structure.
Focus on the output, not the rule numbers
The rule numbers are different between the two systems, but the resulting citations are usually the same. If you know what the citation should look like, you can find the supporting rule in either manual.
Does It Matter Which You Learn?
In practice, no. The two systems produce virtually identical citations for the sources you will cite most frequently: cases, statutes, and constitutions. The differences are mainly in formatting conventions for secondary sources and in the organization of the manuals themselves.
If you learn one system well, switching to the other takes a few hours of focused study, not a semester. The underlying logic of legal citation — identifying the source, directing the reader to the right page, and indicating the authority's weight — is the same in both systems.
That said, if you plan to work on a law review, learn the Bluebook. If your school teaches ALWD in your 1L legal writing course, use it there and learn the Bluebook when you need it. The important thing is to master the logic of citation, not to memorize the rules of a particular manual.
