Please check out the two links I have added that have digitized medieval manuscripts on them. I believe one site is new; Catalogue of Digitized Medieval Manuscripts, and one has been around for a while: The Digital Scriptorium. They are both fantastic sources, and what is nice, is that there is documentation of where to find these manuscripts. Again, please share any time you have visited a special collection and seen a medieval manuscript. What were your thoughts? What did you see? What impressed you most?
I am still looking for other artists to share their work on this blog. If you know any artists that have created new work from medieval manuscripts, please send my blog to them in the chance that they might want to talk about their work here.
