Works in their entirety are underlined.

Smaller works within a larger work are put in quotation marks. So The Collected works of Edgar Alan Poe is underlined, but “The Cask of Amontillado” goes inside quote marks. With PCs you may substitute italics for book titles, but not for both book titles and short stories contained therein.SO: Oliver Twist is underlined or italicized; “Chapter 5: I Am Eaten by Sharks” goes inside quotes. The Poems of Ogden Nash is underlined or italicized; “The Panther” is in quotes. Bad underlined is the album by Michael Jackson; “Bad” in quotes is the song on that album. This also helps to avoid confusiuon when play tiles are character names — Hamlet (underlined or italicized, the play) vs. Hamlet (no indication, the character).

RE:
How do you properly write the title of a short story. Italics or quotations?
Haha, summer break totally had it's effect on me.
