Dr. Eric J. Johnson is Professor and Head of Thompson Special Collections at The Ohio State University Libraries, where he oversees the collection development, teaching, and outreach activities of the department. In addition, he is Lead Curator of the Rare Books & Manuscripts Library and Curator of the Herman J. Albrecht Library of Historical Architecture, and the Interim-Head of the Libraries' Area Studies department. Johnson teaches widely across the University’s interdisciplinary humanities curriculum, with particular emphasis on manuscript studies and book history (ancient to modern).

Dr. Johnson holds a M.A. and Ph.D. in Medieval Studies from the Centre for Medieval Studies at the University of York (UK), as well as a M.L.I.S. from Rutgers University. His research interests extend widely across the fields of medieval and Renaissance studies, codicology and bibliography, book history, the pedagogical uses of primary source materials in K-12 and university classrooms, and the digital humanities. He is particularly interested in “fragmentology,” an emerging subfield of manuscript studies invested in the reconstruction of medieval books and the recovery of their dispersed leaves and lost (or obscured) histories.
