Although the poems of Emily Dickinson remained virtually unpublished during her lifetime, she did engage in a private kind of self-publication from about 1858 to 1864. During those years, she made copies of more than eight hundred of her poems, gathered them into forty groups, and bound each of these gatherings together with string to form booklets. While she sometimes sent a friend a copy of one of the poems from the booklets, there is no evidence that she showed them in their bound form to anyone.
