                               11. ITALIC

    (See also ``Abbreviations and Letter Symbols'' and ``Datelines, 
                      Addresses, and Signatures'')

  11.1. Italic is sometimes used to differentiate or to give 
greater prominence to words, phrases, etc. However, an 
excessive amount of italic defeats this purpose and should be 
restricted.

Emphasis, foreign words, and titles of publications

  11.2. Italic is not used for mere emphasis, foreign words, or 
the titles of publications.

  11.3. In nonlegal work, ante, post, infra, and supra are 
italicized only when part of a legal citation. Otherwise these 
terms, as well as the abbreviations id., ibid., op. cit., et 
seq., and other foreign words, phrases, and their 
abbreviations, are printed in roman.

  11.4. When ``emphasis supplied,'' ``emphasis added,'' or 
``emphasis ours'' appears in copy, it should not be changed; 
but ``underscore supplied'' should be changed to ``italic 
supplied.''

  11.5. When copy is submitted with instructions to set ``all 
roman (no italic),'' these instructions will not apply to 
Ordered, Resolved, Be it enacted, etc.; titles following 
signatures or addresses; or the parts of datelines which are 
always set in italic.

Names of aircraft, vessels, and spacecraft

  11.6. The names of aircraft, vessels, and spacecraft are 
italicized unless otherwise indicated. In lists set in columns 
and in stubs and reading columns of tables consisting entirely 
of such names they will be set in roman. Missiles and rockets 
will be set in caps and lowercase and will not be italicized.

  11.8. The names of legal cases are italicized, except for the

Scientific names

  11.9. The scientific names of genera, subgenera, species, and 
subspecies (varieties) are italicized, but are set in roman in 
italic matter; the names of groups of higher rank than genera 
(phyla, classes, orders, families, tribes, etc.) are printed in 
roman.

caps, or boldface, even if there is italic type available in 
the series.
