Punctuation with Quotation Marks

Always put a comma or a period inside the closing quotation marks even though the comma or the period is not part of the quoted material. Notice the correct placement of the comma in this example:

After I read “Song of Myself,” I had a new appreciation for Whitman and the transcendentalists.

Always put a semicolon or a colon outside the closing quotation mark, as shown in this example:

Muhammad Ali always called himself “the greatest”; his performance lived up to his boast.

Place a question mark outside quotations, except when the question mark is part of the quotation itself. Consider the following examples:

Was it Thoreau who said, “Simplify, simplify”?
I stopped to ask myself, “Is this really where I want to go?”

Which sentence is correct? One of my favorite poems is Robert Frost’s “The Road Not Taken;” it always makes me wonder about options I have not chosen. Although Etta printed several copies of her “Ten Rules for Seasoned Travelers,” she forgot to hand them out to us.
