The 4th installment of the Virtual Encounters on Book History series, organized by Pablo Alvarez (University of Michigan) and Benito Rial Costas (Universidad Complutense de Madrid). Our fourth webinar is a celebration of two landmark publications based on the extensive collection of Greek manuscripts at the University of Michigan Library: Nadezhda Kavrus-Hoffmann, Catalogue of Greek Manuscripts at the University of Michigan in Ann Arbor. Vol. 1. Ann Arbor, MI: University of Michigan Press, 2021; and Julia Miller, Tradition and Individuality: Bindings from the University of Michigan Greek Manuscript Collection. Ann Arbor, MI: The Legacy Press, 2021. Our speakers will focus on various aspects of this important collection of manuscripts, presenting case studies that illustrate their historical, textual, and artistic relevance.
