The Polish Institute of Arts and Sciences of America (PIASA) regrets that, given the on-going restrictions on travel and gatherings occasioned by the COVID-19 pandemic, it must reschedule its World Congress of Polish Studies in Białystok, Poland, originally planned for June 10-13, 2021.  A new call for papers and complete panels will be issued in the fall for the rescheduled Congress, which will be hosted by the University of Białystok in June 2022.  In the meantime, those who have already booked hotel reservations and/or airline tickets should cancel them as soon as possible.
