At Special Collections & Archives in GMU Library there are Primer Interloquium XXI materials in Box 20 Folder 23 and in Box 11 Folder 13 of Warfield Special Collection, but I am not sure they have this course announcement, so I scanned it for home computer. If they do have it my guess it might be the document in Warfield Special Collection Fenwick Library Box 83 Folder 12. I am cataloging all this Primer Interloquium long distance trying to compare my notes of the conference with what I can see on the electronic Finding Aid at Special Collection and Archives. I saved a digital file of this particular brochure because it gives a good overview of what was intended for the conference, and also includes names of the principal organizers and officials behind the conference (Guanajuato Siglo XXI Foundation) as well as short bios of the visiting international speakers, of which Warfield was one. I might add that a year or so later Reynaldo Trevino sent us a complete photograph album full of photographs of persons attending this conference. We did not know the names of most of them. I got Roxana Cardenas to tell me the names of a few, but even she did not know them all. Cardenas was at the conference but she was assigned to a minor backstage role, working as a translator in the broadcasting booths upstairs in the big auditorium. Every speech was translated live into English over headsets provided to the audience and Roxana was one of the few competent to do that. Maybe I will scan all those Guanajuato photos, some day and add them to the database. Not today. R.W. 20 Sept 2011.
