Thanks for your replies...
What I meant was that, some fields there isn't much change going on (ie, I compared my CMDT in Internal medicine from 2003 to 2006 and there weren't many changes)
I would think the management in EM is changing quite a bit. So I wouldn't want to use some management tool from a text and be frowned upon for using something outdated (which has happened once already).
Okay, my real question is... When's the 7th coming out????
