Use single quotation marks for quotations printed within other quotations:
- "When I was a student," she reminisced, "someone said to me, ‘Be sure to enjoy this time of your life.'"
Use single quotation marks in headlines:
Periods and commas should be set inside quotation marks; colons and semicolons should be set outside. Exclamation points and question marks that are not part of a quotation also go outside.
- The instructor said, "Good morning, everyone," but the fire alarm went off before he could say another word.
- The coach said to "print Sports Center hours at the bottom of the brochure"; I don't know what they are, though.
- Didn't you hear her say, "Reading assignments are due every Friday"?
Indicate an omission within a quotation by using an ellipsis (three periods evenly spaced between words):
- "I...tried to do what was best."
If the omission occurs at the end of a complete sentence, add a period at the end of the ellipsis, followed by a space:
- "At the University we are committed to a liberal arts education.... We develop our degree programs with this in mind."
Titles of songs, articles, book chapters, poems, photographs, lectures, individual titles from a series, unpublished works, etc., should be set in quotation marks:
- "Drops of Jupiter," sung by Train
- Stieglitz's "The Steerage," 1907 (photogravure on vellum)
- "Video Provocateur" from the Distinguished Teaching Humanist Series
Italicize titles of books, films, magazines, newspapers, journals, television and radio programs, major musical compositions, plays, gallery exhibitions, and works of art:
- Blackboard Jungle
- New England Journal of Medicine
- American Idol
- Madama Butterfly
- Arrangement in Grey and Black: The Artist's Mother
