Q. Our writing department uses Chicago’s style of putting spaces between the periods in ellipses. The graphic designers argue that in typesetting, the space is much smaller, and so use the ellipses character that is built into our publishing software. Who is correct?
A. Everyone is correct. Chicago uses the spaces, but not everyone follows Chicago style. Someone in your department just needs to pick a style and stick with it. If you use the ellipsis character, make sure your typesetters know whether you want spaces between the dots.
