The fact that this has been posted multiple times defeats its purpose, but i'm pretty sure there is a correct answer on the other post.
If you are asking how to properly write the title then you should Put quotation marks around the poem's title unless it is a novel-length epic poem, such as "Paradise Lost" or "The Divine Comedy." In that case, italicize or underline the title. Cite the poem with a parenthetical citation if you are using MLA or APA format.
