JORDANUS: An International Catalogue of Mediaeval Scientific Manuscripts
From the project website (accessed 2016-01-12):
Jordanus, an International Catalogue of Mediaeval Scientific Manuscripts, provides information about mediaeval manuscripts written in Western Europe between 500 and 1500 A.D., which deals with mathematical sciences, i.e. arithmetic, algebra, geometry, trigonometry and mechanics. It is the result of research projects that were funded by the Volkswagen Foundation (1977-1985) and the Deutsche Forschungsgemeinschaft (1985-1989). The database was originally set up at the Lehrstuhl für Geschichte der Naturwissenschaften of the Ludwig-Maximilians-Universität in Munich by Prof. Dr. Warren Van Egmond and Prof. Dr. Andreas Kühne, and was later brought online by Dr. Gerhard Brey. It was provided an internet platform by King's College (London University) in cooperation with the Max Planck Institute for the History of Science in Berlin (Prof. Dr. Jürgen Renn). Jordanus is now available again on the server of the project Ptolemæus Arabus et Latinus at the Bavarian Academy of Sciences in Munich. It was restored and reinstalled by Erwin Rauner.
