Do you know Chicago style for number ranges? Is it 142–3, 142–43, or 142–143? This workout, on inclusive numbers, covers paragraphs 9.62–66 in CMOS 18.

Chicago style for inclusive numbers is formulated to be efficient and unambiguous—but it is admittedly a bit tricky to apply. Even advanced editors might wish to take a look especially at the table in paragraph 9.63 before answering the questions.

Chicago Style Workout 12: Inclusive Numbers

1. An en dash used between two numbers implies up to and including, or through.
2. If from or between is used before the first of a pair of numbers, the en dash should not be used (from 1898 to 1903) (between 150 and 200).
3. Inclusive spelled-out numbers may be joined by an en dash (forty-five–forty-nine years).
4. Very large inclusive page numbers do not require commas (12991–1301).
5. For inclusive number ranges less than 100, use all digits (3–10) (71–72) (96–117).
6. For 100 or multiples of 100, use all digits (100–104) (1100–1113).
7. For 101 through 109, 201 through 209, etc., use the changed part only (101–8) (808–33) (1103–4).
8. For 110 through 199, 210 through 299, etc., use two digits unless more are needed to include all changed parts (321–28) (498–532) (1087–89) (1496–500) (11564–615) (12991–3001).
9. When years are labeled with BCE, BC, or BP, the same rules for inclusive numbers apply.
10. When citing or mentioning title of a book or article that contains inclusive numbers, the original form of the numbers should be preserved.
