I don't want to pass around copies until I get permission from John

really don't want to bother them right now. My main concern is to
make sure nothing is lost and that's mostly accoplished (after I check
the download to make sure there's no corruption).

A proper place, especially if a copy can be obtained that reflects Sheldon's own version on the last day he worked on the site, is www.gutenberg.org which probably has a better chance of surviving than any individual's site.
