Manuscripts in the Accessoria collection

Manuscripts in the Accessoria collection: Digital cataloguing and Material-philological analysis was a short, one-year project aimed at digital cataloguing of the Copenhagen part of the Accessoria collection held at the Arnamagnæan Institute. The majority of the collection has never been catalogued and its contents were unknown. Cataloguing methods and practices became one of my research interests, and in March 2019 I presented some of my perspectives on the subject at the 94th Medieval Academy of America Annual Meeting and in November 2019 at the 12th Annual Schoenberg Symposium on Manuscript Studies in the Digital Age. 

My digital manuscript descriptions of Accessoria collection are available on
