En Dash

We follow CMS guidance on the usage of en dashes. See CMS 6.78–6.81 for rules regarding the use of en dashes.

Use an en dash with most ranges of dates, pages, money amounts, and so forth; see the sections Currency, Numbers, and Equations (particularly, spelling out vs. using numerals).

Examples: 1998–1999; July 2005–June 2007; $325–$999

Use an en dash to indicate joint research or development.

Examples: Black–Scholes model; the Berry–Dreman research

Use an en dash for acts of Congress.

Examples: Taft–Hartley Act; Glass–Steagall Act
