Special Collections holds a wide variety of materials from and about the Protestant Reformation. A significant portion of these holdings resides in the Heiko A. Oberman Library, which was gifted to Special Collections after the scholar's death. The library was compiled, in part, during the years that Oberman served as the director of the Division for Late Medieval and Reformation Studies, which he founded at the University of Arizona. Other holdings include several translations of bibles, as well as political broadsheets and pamphlets, the latter written by Martin Luther and contemporaries.
The exhibit is organized around the following themes: Late Medieval Catholicism, Renaissance/Humanism, Printing, Martin Luther, the Bible, Other Reformers, Confessional Conflict, the Impact on Daily Life, and the Afterlife. Co-curating the exhibit are Rare Books Librarian Roger Myers, Regents' Professor Susan Karant-Nunn and Heiko A. Oberman Professor Ute Lotz-Heumann.
