Very specific request, but I'm not American and have no opportunity to travel. I'm going down a rabbit hole that is completely untapped as far as I'm aware, Google will tell you nothing. It's about the Pantocratic party and James Seldon Cowdon (and a constitutional amendment to rename America "The United States of Earth")
To the point, does anyone have access to Louisiana State University Libraries. I would really love to get access to Thomas P. Leathers family papers, (https://www.lib.lsu.edu/sites/default/files/sc/findaid/1548.pdf ) specifically the letters relating to John Cowdon. If anyone is interested in helping out, it would be very much appreciated. I'm only a hobby historian, btw, but I'm planning to collage all my findings some way or another.
