Poland's Holocaust 

Poland’s Holocaust: Ethnic Strife, Collaboration with Occupying Forces and Genocide in the Second Republic, 1918–1947, first published in 1998, concerns the topic of Poland's history in the interwar period as well as in World War II, with particular focus on the uneasy relations between various ethnic groups of the Second Polish Republic. Genocide and Rescue in Wolyn 
Genocide and Rescue in Wolyn, first published in 2000, concerns the topic of massacres of Poles in Volhynia and Eastern Galicia during WWII. Bogdan Musiał, reviewing for Zeitschrift für Ostmitteleuropa-Forschung in 2001, found it to be an unbiased and informative work; however, he noted that there was a lack of engagement with the historical and political context of the events. The Polish Deportees of World War II 
The Polish Deportees of World War II, first published in 2004, concerns the topic of mass deportations of Poles following the Soviet invasion and occupation of Eastern Poland in 1939. Anna Jaroszynska-Kirchmann in her review of this book for the Journal of Cold War Studies wrote that the book is "an excellent teaching tool" that "will likely be of great interest" to scholars interested in either modern history of that region or the topic of forced migrations. Gifford Malone, a US diplomat writing in History: Reviews of New Books, found the volume to be a well written and moving account. Criticism 

Piotr Wróbel considers Piotrowski's works to be "highly polemical and controversial", similar to those by Richard C. Lukas and Marek Jan Chodakiewicz. According to Ukrainian historian Andrii Bolianovskyi, Piotrowski's studies on the Ukrainian-Polish ethnic conflicts rely unilaterally on the way they were conceived and presented by Polish right-wing politicians and the underground press during World War II.
