Bluebook vs. ALWD: What's the Difference?

The Bluebook: A Uniform System of Citation is compiled and published by the editors of the Harvard Law Review, the Columbia Law Review, the University of Pennsylvania Law Review, and the Yale Law Journal. It has been the default citation authority in American legal academia for roughly a century, and it is revised every five years or so. Check which edition your legal writing program requires before you buy — schools often stay on an edition for a year or two after a new one drops, and the pagination and some table numbers shift between editions.

The ALWD Guide to Legal Citation is published by the Association of Legal Writing Directors, originally authored by Darby Dickerson and later edited by Coleen Barger. It launched in 2000 as the ALWD Citation Manual, an explicit competitor to the Bluebook, and it was renamed the ALWD Guide with the fifth edition. Its intended audience has always been law students and practicing lawyers rather than law review editors, and the writing reflects that: full sentences, explanatory sidebars, and 'Fast Formats' boxes that show you the finished citation before making you read the rule.

The Bluebook is a reference book that assumes you already know what you are looking for. The ALWD Guide is a textbook that assumes you do not.

Almost never, anymore. The early ALWD editions deliberately deviated from the Bluebook on several points — most famously, ALWD did not require large and small capitals for book and periodical titles, and it simplified some abbreviation practices. Those deviations created real friction: a student trained on ALWD who joined a journal had to unlearn habits.

With the fifth edition, ALWD abandoned that project and adopted the Bluebook's citation formats wholesale. The stated goal was to teach the same system everyone else uses, better. So if you cite Brown v. Board of Education, 347 U.S. 483 (1954), or 42 U.S.C. § 1983 (2018), you will produce the same string under either book. The residual differences are in how the manuals explain the rule, how they organize it, and how many examples they give you.

That means the practical question is not 'which citation format is correct?' It is 'which book do I want in my hand while I figure out the correct format?'

The Bluebook is split into three physically distinct parts. The Bluepages at the front — printed on light blue paper, with rules numbered B1, B2, B3 and so on to parallel the main rules — give practitioner-format guidance for briefs and memoranda. The white pages in the middle contain Rules 1 through 21, which govern law review footnotes: Rule 10 for cases, Rule 12 for statutes, Rule 16 for periodicals, Rule 18 for internet and electronic sources. The light blue Tables at the back are where you actually live day to day: T1 for jurisdiction-specific reporter and statute formats, T6 for case name word abbreviations, T10 for geographic abbreviations, T13 for periodical abbreviations.

The single most common 1L error is answering a Bluepages question by reading a white-page rule. The two systems differ in typeface conventions and in some abbreviation practices. If you are writing a memo or brief, start in the Bluepages and only follow the cross-reference into the white pages when the Bluepages tell you to.

The ALWD Guide sidesteps that problem by presenting one system — practitioner format — as the default, then handling academic footnote conventions separately in its back matter. Its rules are numbered on their own scheme, so you cannot cross-reference between the two books by rule number. Its appendices cover the same ground as the Bluebook tables: jurisdiction-by-jurisdiction citation formats, abbreviations, and local court citation rules.

This genuinely varies by school, and the variation is driven by one thing: your legal research and writing faculty choose the book, and different programs weigh teachability against journal continuity differently. Programs that prioritize a gentler first-semester learning curve tend toward ALWD. Programs that prioritize having students fluent in the exact book their journals use tend toward the Bluebook. Some schools assign ALWD in the fall and switch to the Bluebook in the spring.

Buy whatever your syllabus lists. Then understand the second-year reality: American law reviews and journals use the Bluebook white pages, essentially without exception. If you are going to write on to a journal, you will need a Bluebook regardless of what your LRW course used, and you will need to become comfortable with the white-page rules and the typeface conventions the Bluepages let you ignore.

Practical rule: if you are only buying one book and you have any interest in journal, buy the Bluebook. If your LRW grade depends on ALWD-formatted assignments, buy both — the ALWD Guide is not expensive, and its explanatory prose will save you time in the first semester.

This is the most visible surviving difference between practitioner and academic citation, and it trips people up when they move from LRW to journal. In law review footnotes, certain sources take large and small capitals: book authors and titles, periodical names in some contexts, and several other categories. In briefs and memoranda, the Bluepages tell you to use ordinary roman type and italics instead — you italicize case names, signals, and case-name-like phrases, and you skip small caps entirely.

Because ALWD teaches practitioner format as the baseline, it handles small caps as a distinct academic convention rather than a default. If you learned citation from ALWD and then get a journal source-and-cite assignment, budget time to learn the typeface rules cold. Editors notice.

Both books also require you to distinguish citation sentences from citation clauses, to place and format short-form citations correctly, and to use id. only when the immediately preceding citation is to a single source. Those rules are the same in both manuals and they are where most points are lost.

Neither manual is binding law. What binds you in practice is the local rule of the court you are filing in, and several jurisdictions have their own official style manuals that displace or modify the Bluebook. New York's Official Reports Style Manual (the 'Tanbook'), the California Style Manual, and the Texas Rules of Form (the 'Greenbook') are the best-known examples. Florida's appellate rules include a citation rule that specifies formats for Florida sources. Some federal district courts specify citation requirements in their local rules or in individual judges' standing orders. Always check.

You may also encounter the University of Chicago Manual of Legal Citation, known as the Maroonbook, which a handful of journals use and which is deliberately more permissive than the Bluebook. The Indigo Book is a free, openly licensed implementation of the Bluebook's citation system, useful when you do not have a physical Bluebook at hand, though your journal will still want the real thing.

The through-line is that citation format is a house style, not a legal rule. Your obligation is to find out whose house you are in and follow that style consistently.

Do not read either book cover to cover. Learn the five or six citation types you will use constantly — cases, statutes, regulations, secondary sources, court documents, and internet sources — and learn where in your assigned book each one lives. Tab those pages physically. Tab your jurisdiction's entry in T1 or the ALWD equivalent, because you will open it more than any other page.

Then drill short forms. Full citations are mechanical lookups; short forms, id., supra, and pincite placement are where students actually lose points, because those rules depend on what came before in the document rather than on the source itself.

Finally, treat citation software output as a first draft, not an answer. Westlaw and Lexis copy-with-reference functions and tools like Zotero produce citations that are usually close and frequently wrong on abbreviations, court identifiers, and parentheticals. Check the output against the table entry.
