I have checked the University of Florida's extensive holdings on Mexico and
have been unable to find the map series the IU professor requested.  It is
possible that he actually was requesting the Carta uso del suelo y vegetacion
(1:250,000) Instituto Nacional de Estadistica Geografia E Information.  Perhaps
this would explain your difficulties finding it.  We only have a partial set
and unfortunately Aguascalientes is not among our holdings.  I'll be very
interested to learn if this other series does exist.
