This coming Friday and Saturday, the 30th and 31st, the Helmerich Center for American Research here in Tulsa will present "Dislocations and Migrations," an interdisciplinary symposium of academics, activists, archivists, curators, librarians, and other experts -- all of them exploring ideas of displacement, departure, arrival, relocation, removal, escape, and so on. Our guest on ST, the journalist Jessica Bruder, will be the keynote speaker at this upcoming gathering.
