Okay, I may just be an idiot (hard to tell from where I'm sitting), but I just saw that Crisis of Conscience was revised and updated in May, 2002. I checked over at BN.com and they have the older, third edition.
If everyone already knew there was an update, sorry! If not, the only place I've seen the new edition is over at commentarypress.com.
Here's a link I hope works!
