Who this book is for

For beginning US law students and writers who need citations that help a reader identify and locate the relevant authority. It is particularly useful alongside early legal research and writing assignments, where getting the type of source right matters more than copying a punctuation pattern without understanding its purpose.

Prerequisites

Recognize the difference between a judicial opinion, a statute and a secondary source. No citation system needs to be memorized before starting; keep the source itself available while practicing.

What it covers

The guide explains citation purposes, source categories, common formats, abbreviations and the placement of citations in legal prose. Examples and cross-reference tables connect the tutorial with major academic citation manuals and jurisdiction-specific practice. It treats citation as a usable system of communication rather than a purely mechanical list of typographic rules.

How to use it

Start with one real opinion or statute. Identify the issuing body, source, date and precise passage before building the citation. Compare your result with an example of the same source type, then check the applicable court or assignment requirements. Read a citation backward as well: use each component to retrieve the authority and test whether it supports the sentence you wrote.

Edition and sources

The author’s 2026 revision reflects the twenty-second Bluebook edition and relevant citation practice. Cornell’s official PDF identifies Peter W. Martin and provides the complete guide without charge. The e-book is copyrighted; free reading is not a general reuse license. No ISBN is supplied. Use the current guide and local instructions when a citation convention changes. Publisher or author record.

A source-identification check

For a first practice route, use the official 2026 PDF, §§1-200 and 1-600 for purpose and citation norms, then 2-200/2-300 for opinions or legislation and 6-200 for a citation’s relation to the sentence. Identify the issuing body and precise location before formatting. A retrievable citation can still point to an inapplicable version, nonbinding source or passage that does not support the claim. Keep US citation practice separate from an England-and-Wales course’s instructions; this reference is not a full legal-method curriculum.
