I'm very pleased to report that my students at the Simmons School of Library of Information Science have published another digital reconstruction of a Book of Hours dismembered and scattered by Otto F. Ege. These leaves are no. 28 in his "Fifty Original Leaves of Medieval Manuscripts" portfolios - those of you with that particular portfolio in your collection, take note! There is enough evidence in the thirty recovered leaves to ascribe this manuscript to the Use of Metz. See the reconstruction here:

You'll find more information about other reconstructions (those undertaken by myself, my students, and other scholars) in this blogpost: https://manuscriptroadtrip.wordpress.com/2019/07/14/manuscript-road-trip-fragmentology-in-the-wild/
