A citation becomes easier to build when each component has a job.

Follow a source from the first full citation through pinpoints, quotations, signals, short forms, and a final document audit. Learn to distinguish what a source says from what a writer wants it to establish.

A volume selects a publication sequence. A first page identifies a report. A pinpoint locates the passage that supports the sentence. A signal explains how the passage relates to the claim. Once those jobs are clear, unfamiliar citations become problems you can reason through.

The Citation Code starts with one case and one sentence, then adds placement, signals, quotations, short forms, and source-specific conventions. Editing chapters bring those decisions together in a document. A capstone supplies an entire fictional source packet so you can check the work yourself.

  • Every chapter opens with a real problem and ends with nine exercises and explained answers
  • Annotated model citations break each component into what it means and what to check
  • Worked editing sessions show the decisions, not just the finished citation
  • Reference tables, a 50-state official-source directory, glossary and subject index
  • Advanced chapters on academic editing, foreign, international, Tribal and archival sources

A formatted citation identifies a source. The source's text must also support the proposition, and its legal force must fit the argument. The book keeps those checks separate, and so does this site.

Author

Matthew D. Giron – the author and editor of The Citation Code.

The Citation Code grew out of a simple frustration: citation manuals tell you the rule, but rarely let you practice it and check your own work. This handbook keeps the national baseline, shows every decision in a worked example, and makes the limits of each check explicit, so a reader learns to reason through an unfamiliar citation instead of guessing.

The book adapts public-domain conventions from The Indigo Book and adds original explanations, 207 exercises with explained answers, and advanced chapters on academic, foreign, international, Tribal and archival sources.
