Editorial Tip

The tips provided here, which will be changed regularly, are based on our experience in editing geoscience manuscripts. For a collection of past tips, go to Archived Tips.

  numerical ranges: The following common-sense guidelines are reproduced from the Alberta Energy and Utilities Board Style Guide. They have been modified to reflect the fact that modern word-processing software makes it easy to use the en-dash in this context, rather than the hyphen, because a pair of numbers joined by an en-dash will not break between lines.

En-dashes are used to show inclusion (e.g., 19681972; p. 3845), but are used only if the number range is not introduced by a preposition. If the range is introduced by a preposition, words must be used:

...from 1968 to 1972 (never from 19681972).
...between 1968 and 1972 (never between 19681972).

The same guidelines apply to ranges in geochemical values:

Zinc values ranged from 100 to 250 ppm.
Zinc values in the range 100250 ppm are characteristic of these rocks.
