Q. In referring to a publication, I know the title should be in italics. But if a longer title such as Looking Back: A Seventy-Fifth Anniversary of Phi Eta Sigma National Honor Society is shortened to Looking Back, should quotation marks be added to the italics?

A. No. If the full title is italic, the shortened version should also be italic. Please see CMOS 14.30 for examples of shortened titles.
