The theme for Mythcon XXXVII is The Map & The Territory: Maps and Landscapes in Fantasy, and the conference will have a dedicated track on Native American Fantasy/Native Americans in Fantasy.
The Author Guest of Honor is Lois McMaster Bujold (who, incidentally, is perhaps my favorite living author).
The Scholar Guest of Honor is yours truly. No, I can't believe it, either. :)
The Call for Papers is available here. The conference site (still under construction) is here.
The conference will be held August 4-7, 2006 on the campus of the University of Oklahoma in Norman, Oklahoma, USA.
