The letters of Louisa Van Velsor Whitman have been made publicly available on the Whitman Archive. In addition to 170 letters from the period 1860 to 1873, the Archive also includes Wesley Raabe's extensive introduction to Louisa's letters. The publication of these materials, which coincides with Women's History Month, is the culmination of many years of work and marks a major addition to the Whitman Archive. The letters illuminate the most important relationship in the poet's life and offer a rare glimpse into the emotional life of a working-class nineteenth-century American woman.
