hey folks i notice in some scientific papers, where they list the correspondence info, it sometimes says, "Corresponding author: John Selmack, Dpmt of This, Univ That. USA." less frequently, it will say, "Reprint request to: John Selmack, Dpmt of This, Univ That. USA." these differences can be found in the same issue of the same journal. why are there two ways of denoting the corresponding author? are they implying that in the 2nd case, that particular author ordered reprints? why does that private information even matter to the readership? i can't think of any other "definition" that could lead to the difference.
