Headlines and Titles of Works

Q. Quotation marks in titles and subheads seem inappropriate, except those required when referring to particular works. However, I can find no reference to support my position in Chicago or elsewhere. I’m supposing that is because scare quotes in heads are a rare occurrence.

A. Quotation marks in titles and subheads are required whenever something is quoted. Although Chicago discourages the impulsive use of scare quotes, sometimes they are appropriate, even in titles, so you won’t find a rule against them in CMOS.
