This page has a list, ordered by library, of manuscripts involved in the project - watch it grow!
Where possible, the manuscript shelfmarks provide links to digital facsimiles. At this point, I'd like to say an enormous thank you to all the libraries, archives, and funding bodies who have put so much time, effort, and financial support into digitising manuscripts in recent years - this has allowed my research to continue despite the inability to access manuscripts in person during the pandemic.
