And if nobody has it, maybe someone will help me figure out how to get a
 copy from one of the libraries that has the Arch. f. d. Psych.:

 Lots in Germany, a few in France, and one in Zurich.  Any volunteers?
 I also found a commentary that said the time-difference that Klemm found was
 1/100 $\sigma$; some looking around informed me that $\sigma$ was an old
 abbreviation for a millisecond, so this is 10 microseconds.  Seems a lot
 more reasonable than the 2 microseconds that another book talked about.  I'd
 like to see what else he said (I think I can make out German almost well
 enough to get the gist of it).
 As far as I can tell, this may be the first guy to investigate inter-aural
 time difference of clicks and complex sounds (as opposed to just inter-aural
 phase difference of sinusoids).

 Otto Klemm apparently did great work on binaural localization, including
 time-intensity trading. But I can't find a clear statement of how small a
 time difference he found to be detectable. One paper says 2 microseconds,
 but I suspect that's wrong.
 I have his 1913 and 1914 papers (freely available online), but can't find
 these more important later ones:
 Klemm, Otto (1918). Untersuchungen uber die Lokalisation von Schallreizen.
 3. Mitteilung: Uber der Anteil des beidohrigen horens. Archiv für die
 gesamte Psychologie, 38, 71-114.
 Klemm, Otto (1920). Untersuchungen über die Lokalisation von Schallreizen.
 4. Mitteilung: Über den Einfluß des binauralen Zeitunterschiedes auf die
 Lokalisation. Archiv für die gesamte Psychologie, Bd. 40, 117146.
 Does anyone have or know where to find them?
