There is no formal title to this poem. As with most poems without titles, it’s referred to by its first line. In general, Dickinson’s poems are also accompanied by numbers corresponding to the order in which she wrote them. (This one is usually known as "754.") However, considering there is no key indicating the order of her work, scholars disagree constantly. In other words, there are different number sets, which means titles can become confusing. To be on the safe side, stick to the first line.
