If you are citing an untitled poem known only by its number, a generic description of the poem can be substituted for the title in the works-cited list and in the in-text citation, if necessary. For instance, in an essay about Shakespeare’s sonnets, you might write the following:
Shakespeare’s sonnet 130 is an anti-Petrarchan poem, negating the conventions of love poetry Petrarch had made popular. It begins with an unflattering comparison: “My mistress’ eyes are nothing like the sun” (line 1).
