I wish especially to thank Zdeněk Horský for generously supplying a detailed list of annotations in the Strahov Library copy, and Grazyna Rosińska for help at the Polish Academy of Sciences Library in Cracow. Mary Smyth at the Crawford Collection, Royal Observatory Edinburgh, and Friedrich Seck, University of Tübingen, have helped make my visits to those libraries both efficient and enjoyable. Travel funds for this research were generously provided by the Copernicus Society of America and by the Secretary's Fluid Research Fund of the Smithsonian Institution.
