about the project introduction The Cornell Historic Math Monograph Collection consists of digital surrogates for materials that were part of a joint study involving Digital Preservation between Cornell University and the Xerox Corporation. Begun in 1990, a process was developed where brittle and decaying books were digitally scanned, using prototype equipment co-developed by Cornell and the Xerox Corporation (the CLASS scanner) and stored as 600dpi, bitonal TIFF images, compressed with ITU Group 4 compression, on digital platters on an EPOCH "jukebox" digital server. Facsimiles of these books were generated and the books were returned to the shelves. The images were available online using specially developed clients in Unix, MAC and PC platforms.
In the autumn of 1609, the Italian mathematician and astronomer Galileo Galilei turned his telescope to the heavens, deciphering the cratered face of the moon, the four satellites of Jupiter, and other previously opaque features of the heavens. When, in 1610, Galileo published his Sidereus Nuncius, or Starry Messenger, the German astronomer Johannes Kepler responded with enthusiasm, praising the significance of Galileo’s observations with his own Dissertatio cum Nuncio Sidereo, or, Conversations with the Starry Messenger (1610). To whom else did the stars speak in the early modern period?
