the newer Emerald books are substantially different than the older ones 
(for one thing, they don't say "sensitive electronic equipment" any 
more... the mfrs complained that they didn't want their equipment being 
thought of as "sensitive")

IEEE 1100-2005 recommended practice for Powering and Grounding 
Electronic Equipment.

(there might be a newer one coming out.. I think it's every 6 years or so)

Section 4.8 is all about single point grounds, signal reference systems, 
etc.

Section 4.10 on surge suppressors is pretty sketchy, dealing only with 
the various shunt mode devices.

I like Standler's book on this topic.  he covers series mode transient 
suppression, the problems with shunt mode (e.g. inducing a transient 
after the suppressor by induction, etc.)
