My workplace naturally has the capability of duplicating pretty much any media to any form. Around once a year, I get someone who wants us to duplicate Hovind or Comfort or some other bigoted idiot. All I have to say is the magic word 'copyright' and the perp is dumbfounded.
I seem to remember that Hovind has waived copyright where his works are used for educational purposes without charge.
I'm way too lazy to look this up.
