Consult the Chicago Manual of Style for punctuation rules not outlined below.

ampersand. Do not substitute for and in body copy [WRONG: He is professor of philosophy & religion. RIGHT: He is professor of philosophy and religion.]. If an ampersand is used instead of the word, such as in the name of a firm, omit the serial comma [She worked for Hardy, Smyth & Jones LLC].

apostrophe. No apostrophe in uppercase abbreviations [POWs, GEs, MAs, As and Bs. Use ’70s, not 70’s]. To avoid confusion, use an apostrophe with abbreviations that combine uppercase and lowercase letters [We offer MAs and PhD’s.]. Note direction of apostrophe when it precedes numerals such as a year or decade; to achieve ’ before
numerals, on a Mac, type shift/option/apostrophe, and on a PC, type control/shift/apostrophe.
          PLURALS AND POSSESSIVES. If a noun is plural and ends in s, add only the apostrophe [Both writers’ novels were accepted for publication.]. The plural of a word referred to as a word without regard to its meaning is indicated with an apostrophe and an s [You have given me too many but’s already.].
          In general, the possessive of most singular nouns is formed by adding an apostrophe and an s, and the possessive of most plural nouns by adding an apostrophe only.
          The general rule applies to proper nouns (including names ending in s, x, or z) in both singular or plural form, as well as letters and numbers [Marx’s comedy, Dickens’s novels, Gutierrez’s house, 2004’s rainfall record].
          Exceptions to the general rule include nouns that are plural in form but singular in meaning, including place or organization names that are in plural form ending in s whose entity is singular [politics’ ultimate impact, the United States’ economy after World War II]; words ending in an eezsound, and words and names ending in an unpronounced s [Euripides’ tragedies, Descartes’ philosophy]; and for . . . sake expressions when the noun ends in an s or an s sound [for goodness’ sake, for righteousness’ sake].
          To indicate joint possession or closely linked proper names treated as a unit, use an apostrophe with the last noun only [Joe and Mary’s house]. To show individual possession, make each noun possessive [Joe’s and Mary’s clothes were hung on the clothesline.]. Apostrophes also imply of in the genitive case [an hour’s delay, in three days’ time]. Consult the Chicago Manual of Style for other exceptions and guidelines.
          Avoid common misuses of apostrophes such as using an apostrophe with a noun that is not possessive [WRONG: Do not drive through the barrier’s. RIGHT: Do not drive through the barriers.].

brackets. Corrections, explanations, or comments within quoted material, or editor’s notes, should be bracketed [“People [here in Iraq] have the right to express themselves. That’s why I’m here.”]. Brackets are also used as parentheses within parentheses [Writing intensive courses (both in the humanities [four] and social sciences [three]) will be held next year.].
