Capitalization in Titles of Works

Q. If our publication follows your style of italicizing the titles of most works (e.g., books), what would you recommend we do in cases when that title must appear in the headline of an article? Italicization is not possible in our headline fields, and our style for quotation marks in headlines is single quotation marks. Single quotes would likely improve clarity in many cases, but it may also be best to use quotation marks only when needed for clarity. I would appreciate some reinforcement as we try to pin this down for good.

A. Since you are more or less limiting your choices for styling titles in headlines to (1) using single quotation marks, (2) not using quotation marks, and (3) using them inconsistently, I vote for number 1.
