š What Is the Bluebook Style?
The Bluebook citation system is maintained by editors from four major law reviews: Harvard, Columbia, University of Pennsylvania, and Yale. Itās considered the gold standard for legal citation in the U.S.
The Bluebook uses footnotes for legal academic writing (law review format) and in-text citations (court documents and memoranda, known as āBluepages formatā).
š Bluebook Citation Formats: Two Systems
- Bluepages (B1āB21):
- For legal memoranda, court filings, practitioner documents
- Uses in-text citations
- Whitepages (Rules 1ā21, Tables):
- For academic legal writing (e.g., law review articles)
- Uses footnotes
This guide primarily focuses on law review format (footnotes) but will highlight key differences for practitioner documents when applicable.
