The Nazi Persecution of the Gypsies

My knowledge of the persecution of the Roma/Sinti people during the Holocaust was minimal, at best.  Reading Lewy's book, The Nazi Persecution of the Gypsies, certainly added to my knowledge base; however, I am sure of all of the information provided by the author.  In speaking to historians and scholars (I am an avid attendee of workshops provided by the Illinois Holocaust Museum and Education Center) their opinions and research has contradicted Lewy's.  Nonetheless, I feel I have gained valuable knowledge about the Roma/Sinti people.  I will continue to pursue the available resources on the persecution of the gypsies.
