There are an estimated 30,000 to 35,000 mediaeval western "scientific" manuscripts scattered throughout the world. Many attempts have been made to catalogue them, from the early seventeenth century hand-written catalogues to the present-day printed catalogues. Even the most recent catalogues, however, cannot be updated or corrected at a reasonable cost. A computerized catalogue, on the other hand, can be updated, corrected, printed and made available to a wide range of users at any time and at low cost.
Jordanus, an International Catalogue of Mediaeval Scientific
now made available by the Institute for the History of Science at the
University of Munich and by the Max Planck Institute for the History
of Science in Berlin. The database is accessible on the
internet by any current net browser. It provides information about
mediaeval manuscripts written in Western Europe between 500 and 1500
A.D. which treat the mathematical sciences in the wider sense, i.e. arithmetic, algebra, geometry, trigonometry and mechanics.
