In 1923, the famous theologian-librarian Adolf von Harnack responded to an essay written by Ferdinand Eichler, Director of the University Library at Graz, titled "Library Science as Science of Value, Library Politics as World Politics." In the exchange, the two librarians took opposing sides in a discussion about the purpose of academic libraries and collection development. Eichler's idealistic and universalist approach saw librarianship as a “science over the sciences” that held a unique responsibility for world culture through its responsibility for books. Harnack, on the other hand, took a more pragmatic approach and recognized the limitations posed by political economy to the mission and practices of the library. Although published a century ago, the political pressures and vocational ideals discussed in these essays remain surprisingly relevant for theological librarianship. In this presentation, I will present on Harnack’s underappreciated role as the director of the Royal Prussian Library, discuss the Eichler-Harnack exchange, and share about my work translating the two essays into English for the first time.
