•The PDF version is backed up on a local server
–The purpose is to maintain an access copy rather than support an electronic archive
–Supplementary enhanced theses with multimedia files are backed up locally but are not treated to
preservation procedures or submitted
to UMI.
•The PostScript is also backed up on a local server
–PostScript is an established format, unlikely to become obsolete; as a last resort it can easily be converted to
TIFF, a format that any image reader can access.
•The content of a PostScript file can be preserved on fiche
–It is converted to PDF then sent to UMI where it is filmed and preserved in the NLC fiche archive.
