IllumiNet Press
First and foremost (from a Discordian standpoint, at least), the IllumiNet
Press publishes the
Principia Discordia.
However, they also publish a lot of other really cool
titles
like
The Mothman Prophecies,
The Idle Warriors,
Zenarchy and
Visionaries, Mystics & Contactees.
If you send them a couple of extra dollars and request that they send you
anything that they have lying around, they will, indeed, send you something
cool. Hell, they'd probably send you something cool even if you didn't
pay extra for it.
You can contact them at IllumiNet Press, PO Box 2808, Lilburn, GA 30226
or check out their
web site.
