1. Rule #1
Titles

2. Italics/Underlining
Italics are used for BIGGER works (titles of books, plays, magazines, movies, TV shows)
When handwriting, italics becomes underlined
Easy way to remember:
The BIGGER works have the ENTIRE title modified by the formatting (either italics or underlining applies to every letter of the word)

3. Quotation Marks
“Quotation Marks” are used for SMALLER works (short stories, poems, magazine articles, episodes of a TV show)
Put punctuation marks INSIDE the quotation marks: Edgar Allan Poe wrote the short story “The Cask of Amontillado.”
Easy way to remember:
The SMALLER works have only two SMALL quotations, not the entire title modified
