Ebsco seems to have fixed "United States" but now how about "adult"?
about how my most commonly returned cluster for Inspec was "United States" -- this has apparently been fixed (based on my experience)....
So now I'm searching in CINAHL (a database with most excellent indexing)... and ack! The recommended subjects start out (seemingly always) with male... female... adult... Ok, so this makes sense, because it's grouping all of the subjects together. But come on, is that what I need?
