General

En dashes ( – ) are used for inclusive dates and compound words comprised of one or more hyphenated words. Em dashes ( β€” ) are used in place of commas, semicolons, colons, or parentheses for a more emphatic separation of word clauses.

Periods are not used after metric abbreviations: e.g., cm, mm, km

Serial comma, i.e., commas should be used before the last element in a series: e.g., beads, pins, and clocks.

Spell out whole numbers from one through ninety-nine and any whole numbers above followed by hundred, thousand, hundred thousand, million, and so on.

Inclusive page numbers should be separated by an en dash and abbreviated as per CMS guidelines. For numbers less than 100 and for multiples of 100, use all digits: 3–10, 71–72, 96–117, 100–104, 1100–1113. For all other numbers, condense as follows: 101–8, 321–28, 498–532, 808–33, 1087–89, 1103–4, 1496–500. Roman numerals are given in full: xxv–xxviii, cvi–cix.

Inclusive dates should be separated by an en dash and abbreviated according to the rules outlined in CMS: 1504–5, 1914–18, 2000–2001.

Capitalization is used for proper names and those events, movements, eras, etc. that are customarily capitalized (see CMS). Use lower case if there is no precedent.

Spell out centuries: e.g., fifteenth century. Hyphenate centuries when they are used as adjectives: e.g., fifteenth-century painting.

The era designations BCE and CE are rendered without periods.
