Reference Librarian comments

You had a good Medline learning session! I'll bet you know by now
WHY set #1 was a disaster. You were ANDing these terms, getting more
& more restrictive. By set #6 you were doing it right. But, did
you forget the Diabetes concept? I decided to play with this, like
this (below). (I copied the 12 references, in case you're interested
in them, at the very bottom of this message...)
