The beginnings of this series including all Bavarian State Library manuscripts (with a number of sub-series, designated “Tomi,” each consisting of several “Partes”) date back to the 19th century. From 1970 onwards, Harrassowitz has published especially those new catalogues which describe German, Greek and Latin medieval manuscripts in comprehensive, research-oriented articles. New volumes appear on a regular basis. They are standard research publications for manuscripts, allowing deep and detailed insights into one of the world’s largest manuscript collections.
