There are still earlier sites,
under sunsite.unc.edu/lia/prgnet/ which move automatically to the PRGNet
http://www.ibiblio.org/lia/prgnet/ that is
listed above. Google will occasionally
show the sunsite address.
Other sites associated with the PRG
derive from the PresidentS enterprise. Below I show in order the URL's
file name, the heading at the site itself (in quotes), and finally the URL.
