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.
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.
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. These clients were developed at
Library Technology at Cornell University by William Turner III, David
Fielding and Chris Stuart.
