Some more show bibles have appeared (or re-appeared in the case of Dark Skies) on the Internet since my original bible round-up, so I thought I'd better let you have a look at them too.
The Crow: Stairway to Heaven - Bryce Zabel
Dark Skies - Bryce Zabel and Brent Friedman
Callan - James Mitchell
And if you'd rather have dead trees (and who wouldn't, really?) you can also find bibles in the following books:
The Making of Star Trek: Deep Space Nine
Star Trek: Phase II
The Making of Star Trek
Though of them all, it seems that only the DS9 one is actually in print at the moment.
