Dalej jest noc: losy Żydów w wybranych powiatach okupowanej Polski ("Night without End: The Fate of Jews in Selected Counties of Occupied Poland"), co-edited by Jan Grabowski and Barbara Engelking, is a two-volume study published in 2018 by the Polish Center for Holocaust Research in Warsaw, Poland. The 1,600-page study contains nine chapters, each covering a county in occupied Poland in 1939–1945—Bielsk Podlaski, Biłgoraj, Bochnia, Dębica, Luków, Miechów, Nowy Targ, Węgrów, and Złoczów—in the General Government area established by Germany in World War II. The study identifies small Polish towns as "death traps" for Jews in hiding. An abridged English-language version of the study is forthcoming.
