An informal lunch or coffee time to meet virtually with Kislak Curator Dot Porter and talk about one of the manuscripts from Penn's collections. Each week we'll feature a different manuscript and the expertise of other curators. Everyone is welcome to attend. On May 31 we'll look at LJS 225, a presentation copy for Pope Callistus III of a work on cryptography that describes the system in detail.
