the calling function knows there's (effectively) no such record...

That is why we have the read below..

This of course, also means that the notes field had better contain a
lisp sexp.. and anythign after the sexp gets discarded...

If record exists but no notes exist, \"\" is returned. 
Else the string containing the notes is returned.
If no record exists, then a nil is returned.
