Question

In a paper when naming a poem is it underlined, italised, or in quotes?

Answer 1

quotation marks and if youre typing it italisied

Answer 2

It should be in quotation marks.

Answer 3

The most proper way of writing it in a paper, when there is a question and it asks about the title of the poem, it should be written with the quotations marks, thus:

"The Arrow and the Song" by Henry Wadsworth Longfellow

But when writing the title of the poem, the title is centered or in the left side. But I use the centered style.
