Q. Should national anthems—for example, La Marseillaise—be set in quotes?

A. A national anthem is a song by any other name, but with more pomp and circumstance. So whether it’s “La Marseillaise” or “O Canada”—or “March of the Volunteers,” a song written in 1934 and later adapted as the anthem of the People’s Republic of China—put it in quotation marks.
