1) Page to p. and pages to pp. in footnotes or bibliographical material; spell out when used in text material.
2) Eastern Standard Time as EST, without periods.
3) Use the ampersand (&) only in corporate names or if space demands it in course abbreviations.

5) Use GPA in caps without periods.
6) When it is necessary to use a subject-matter designation and course number to identify a specific course, e.g., MAT 111 University Algebra, use the official course code.
8) When names of universities, government agencies, or other organizations are abbreviated as acronyms (first letter of each word), use full caps with no periods: HPER, ROTC.
9) Use a.m. and p.m. with periods and lowercase letters. In tabular matter, the periods can be omitted to save space.
10) Use U.S. in text only as an adjective. Spell out United States as a noun, e.g., the U.S. Senate, but a resident of the United States.
11) Abbreviate these months when they are used with a specific date: January, February, August, September, October, November, December. Jan. Feb. Aug. Sept. Oct. Nov. Dec.

In other text, abbreviate the name of the state when it is used with a city, except Alaska, Hawaii, Idaho, Iowa, Maine, Ohio, Texas, and Utah. Spell out the state’s name when it is used alone. Use the two-letter postal abbreviation with a zip code only in addresses. Do not use the postal abbreviation in running text. The exceptions include classnotes and lists.
4) The name of an organization the first time it is used; spell out and put the acronym in parentheses. If the term appears only once, do not add the acronym.
Acting on AIDS (AoA)
