(3.57) Periods are omitted at the ends of items in a vertical list or enumeration, unless the items are whole sentences or paragraphs (see 2.72):

The report covers three areas:
1.  The securities markets
2.  The securities industry
3.  The securities industry in the economy

(3.58) Periods are omitted at the ends of: (1) display headings for chapters, parts, and the like; (2) titles of tables; (3) captions of figures; and (4) any subheading that is typed on a line by itself.

(3.98) The principal uses of parentheses in the text of a paper are: (1) to set off parenthetical references (PR), (2) to enclose the source of a quotation or other matter, and (3) to set off the numbers or letters in an enumeration (as in this sentence) (see 3.109).

(3.109) Numbers or letters in an enumeration run into the text belonging with the items following them; therefore, sentence punctuation precedes them, and no punctuation mark comes between them and the items to which they apply (see 2.70):

He gave three reasons for resigning:  (1) advanced age, (2) failing health, and (3) a desire to travel.

(3.99) Brackets are used (1) to enclose any interpolation in a quotation (see 5.37) and (2) to enclose parenthetical references (PR) within parentheses (see 3.110):

The book is available in translation (see J. R. Evans-Bentz. The Tibetan Book of the Dead [Oxford:  Oxford University Press, 1927]).

(3.110) Brackets used to set off words or phrases supplied to fill in incomplete parts of a quotation (see 5.35 ? 5.37) or dates supplied in citations (see 8.68) are ignored in punctuation?that is, punctuate as if there were no brackets:

The states have continued to respond to "the federal stimulus for improvement in the scope and amount of categorical assistance programs. . . . [Yet]  Congress has adhered to its original decision that residence requirements were necessary" (Baldwin 1980).

(3.106) In American usage, when a parenthetical reference (PR) is not being used, and when the idea is the writer's thoughts, a comma or a final period always precedes a closing quotation mark (see 5.17):

Every public official and every professional person is called on "to join in the effort to bring justice and hope to all the people."

(3.107) Single quotation marks are used to set off special terms and a period or comma is placed within the closing quotation mark (or marks, when both single and double occur together):

The article he referred to is in the Journal of Political Economy:  "Comment on 'How to Make a Burden of the Public Debt.'"

(3.108) When a complete sentence is enclosed in parentheses or brackets, the terminal period for that sentence is placed within the parentheses or brackets. When elements (comments that are not complete sentences) are enclosed in parentheses or brackets, the sentence punctuation is placed outside the parentheses or brackets:

We have already noted similar motifs in Japan.  (Significantly, very similar motifs can also be found in the myths and folktales of Korea.)

Myths have been accepted as literally true, then as allegorically true (by the Stoics), and confused history (by Euhemerus), a priestly lies (by the philosophers of the Enlightenment), and as imitative agricultural ritual mistaken for propositions (in the days of Frazer).

(4.13) References in text to such parts of a work as contents, preface, foreword, introduction, works cited, and appendix should not be capitalized. Spell out and do not capitalize (unless in a heading or at the beginning of a sentence) the words book, chapter, part, volume, section, page, figure, and table (see 2.18, 4.13, and 6.16):

The variables within the experiment are listed in table 2, and the concept is explained in the introduction.
