Night Without End (history book)

Literary critic Beth Holmgren wrote that Dalej jest noc is a "highly detailed, systematically organized, data-based analysis of how and by whom the Holocaust was perpetrated in nine separate Polish counties".

[5] Ingo Loose, a historian at the Institute for Contemporary History in Munich, said that the book debunks the view that non-Jewish Poles helped Jews en masse or were at worst forced to be bystanders.

He notes the naming of perpetrators and co-perpetrators – individuals who took over Jewish property – and participation by the Polish Blue Police, Baudienst, fire brigades, and military guards.

[8] Historian Adam Kopciowski [pl] similarly commended the usage of "an impressive range of sources", including materials from various organisations and from Polish and Jewish witnesses, which were accessed in the archives in Poland, Israel, the United States, Germany, Ukraine, Belarus, and Russia, which, as he argued, helped them "develop an exhaustive picture of a previously understudied stage of the Holocaust of the Polish Jews".

[10] Many scholars affiliated with the Institute of National Remembrance (IPN) criticized the book severely — in particular, Tomasz Domański [pl] published a 72-page review, followed by a 110-page rebut to the responses by the individual authors.

[11] Other historians found their criticism to be politically motivated, unscholarly, and insignificant; accusing the IPN's reviewers of having adopted a "hairsplitting" approach that involved combing through every footnote and statement for potential errors, they held their polemics as a tool to mainstream the right-wing conception of Polish history — where the Poles had no culpability regarding the persecution of Jews during the Nazi regime since they were, at worst, merely following orders — and push back against all critical narratives.

[18] Engelking said that she was simply reporting a witness's opinion, rejecting any wrongdoing on her behalf[19] and published her detailed response to the accusations and trial on the Polish Center for Holocaust Research website.

[21][22] Zygmunt Stępiński [pl], director of the Polin Museum, said that "[the] involvement in this trial of an organisation heavily subsidised with public funds [could] be easily construed as a form of censorship and an attempt to frighten scholars away from publishing the results of their research out of fear of a lawsuit and the ensuing costly litigation.
