B. Typefaces (See Bluebook P. 1)
In Court documents, only regular roman type and underlining are used. Small capitals, bold type, and italics are not used. The general rule for each type of document is listed below. For specific examples, see the relevant citation section.
Case names: Underline all case names, including the "v." and any procedural phrases such as "In re" and "Ex parte", with one continuous underline.
Introductory signals: (See II.D.) Introductory signals are always underlined when they appear in citation sentences or clauses. Continuously underline combined signals. When an introductory signal is part of a textual sentence, however, it is not underlined.
Explanatory phrases introducing prior or subsequent case history: (See Bluebook T. 9) Explanatory phrases such as aff'd or cert. denied should always be underlined.
Book titles: (See III.G.) Always underline the title of a book or the title of an article appearing in a periodical. Authors' names and periodical titles are not underlined. If an article or essay appears within a book, underline the title of the article or essay as well as that of the book. When referring to a publication in a textual sentence rather than citing to it, underline the name of the publication.
Legislative history: (See III.F.) Treat legislative materials (such as hearings, documents, and committee reports and prints) as books. Underline their titles and print the authors' names (if given) in ordinary type. When congressional reports or documents are cited without author or title, do not underline.
Words and phrases introducing related authority: Underscore "in," "reprinted in," "quoted in," available in," "translated in," "microformed on," and other similar words and phrases referring to related authority:
Cross-references: Always underline "supra" and "id." (including the period).
Emphasis/Foreign words: Underline words for emphasis, foreign words not commonly encountered in legal writing, and words italicized or underlined in the original of quoted matter.
Everything else: Print everything else--including reports, services, constitutions, statutory materials, restatements, model codes, rules, executive orders, administrative materials, unpublished sources, and treaties--in ordinary roman type.
