the bottom consisting of author's name
and professional mailing address.

=Center heads= of whatever level should be typed with initial caps of
major words, with extra space above and below the head, but with no other
preparation (such as all caps or underline). Run-in paragraph heads should
use period/dashes or colons as necessary.

=Tabulations= within text (lists of data, often in parallel columns) can
be typed on the text page where they occur, but they should not contain
rules or formal, numbered table heads.

=Formal tables= (numbered, with table heads, boxheads, stubs, rules)
should be submitted as camera copy, but the author must contact the series
section of the Press for editorial attention and preparation assistance
before final typing of this matter.

=Taxonomic keys= in natural history papers should use the alined-couplet
form in the zoology and paleobiology series and the multi-level indent
form in the botany series. If cross-referencing is required between key
and text, do not include page references within the key, but number the
keyed-out taxa with their corresponding heads in the text.

=Synonymy= in the zoology and paleobiology series must use the short form
(taxon, author, year:page), with a full reference at the end of the paper
under "Literature Cited." For the botany series, the long form (taxon,
author, abbreviated journal or book title, volume, page, year, with no
reference in the "Literature Cited") is optional.

=Footnotes=, when few in number, whether annotative or bibliographic,
should be typed at the bottom of the text page on which the reference
occurs. Extensive notes must appear at the end of the text in a notes
section. If bibliographic footnotes are required, use the short form
(author/brief title/page) with the full reference in the bibliography.

=Text-reference system= (author/year/page within the text, with the full
reference in a "Literature Cited" at the end of the text) must be used in
place of bibliographic footnotes in all scientific series and is strongly
recommended in the history and technology series: "(Jones, 1910:122)" or
"... Jones (1910:122)."

=Bibliography=, depending upon use, is termed "References," "Selected
References," or "Literature Cited." Spell out book, journal, and article
titles, using initial caps in all major words. For capitalization of
titles in foreign languages, follow the national practice of each
language. Underline (for italics) book and
