The collection contains the personal papers of Hodge, including lectures, speeches, articles, books, and correspondence dealing with questions of Presbyterian theology in the mid and latter nineteenth century. Included are manuscripts for Commentary on the Epistle to the Romans (1835) and What Is Darwinism? (1874). The papers reflect Hodge's lifelong association with the Princeton Theological Seminary (PTS) where he taught Biblical literature and theology and supplement manuscript material in the PTS library. The collection also contains personal correspondence between Hodge and his wife, Sarah Bache Hodge, his brother, Dr. Hugh Lenox Hodge, as well as with his mother, Mary Blanchard Hodge, and children. In addition, there are papers by his son, Archibald Alexander Hodge, also a clergyman and, later, his father's successor at the seminary as professor of theology.
