The Thomas Wentworth Higginson Collection at the University of Nebraska–Lincoln is part of the larger Carlton and Territa Lowenberg Collection at the UNL Archives and Special Collections. The Lowenberg Collection's primary focus is Emily Dickinson, and it contains many items of interest collateral to Dickinson, including thirty letters written by Higginson between 1865–1910. In addition to correspondence, the Lowenberg Collection also includes original copies of sermons and other miscellaneous publications by Higginson.
The Higginson correspondence is under the general editorship of Linda Ray Pratt, Department of English, UNL, and is a project of the Center for Digital Research in the Humanities, a joint initiative of the University Libraries and the College of Arts and Sciences. The Center is under the direction of Professors Kenneth Price and Katherine Walter.
