About Bluebook Title Case

It is used by law schools, law review journals, courts, and practicing attorneys for citing cases, statutes, regulations, and legal documents. Bluebook title case follows a preposition-length rule nearly identical to Chicago: prepositions of four letters or fewer are lowercase, while longer prepositions are capitalized.

Bluebook vs Chicago
Bluebook and Chicago produce nearly identical title case outputs because Bluebook's rules closely follow Chicago's 4-letter preposition threshold. Both capitalize prepositions of 5 or more letters and lowercase shorter ones. The main differences between the two systems appear in their citation formatting (Bluebook has extensive legal-specific rules for abbreviations, case names, and statutory references) rather than in the basic capitalization of titles and headings. For standard title capitalization purposes, the two styles are effectively interchangeable.
