<p>Hey guys--I am planning on answering the supplemental essay option #4 on Princeton's supplement. However, the quotation I am planning on using is not from a book or an essay. It's a poem. Do you think it will matter? Just making sure. Thanks!</p>
<p>A poem would be totally fine!</p>
<p>A poem is always part of an anthology, which is a book - so it’ll be fine!</p>
