In the past few months, MITH has been developing software for a project related to the Walt Whitman Archive. The Walt Whitman Archive is an electronic research and teaching tool that sets out to make Whitman’s vast work, for the first time, easily and conveniently accessible to scholars, students, and general readers. Working in collaboration with the University of Texas at Austin, as well as the Center for Digital Research in the Humanities at the University of Nebraska–Lincoln, the project team is focusing on Walt Whitman’s annotations and commentary about history, science, theology, and art being discussed during his time. These annotations survived in many forms, either as marginalia and underlinings on books, or as collages of newspaper clippings, or as separate handwritten notes. Studying this material can further our understanding of the poet’s self-education and his compositional methods.
