Some documents are better than others.
Original documents, for example, are more valuable than documents that are not original, particularly when you want to prove murder. Original documents are even more important when you want to prove mass murder. This is pretty complicated stuff, our holocaust historians have not been able to quite figure it out yet, but Carlos Porter has, and with this little paper he invites you to reflect on some of the documents used by Jean-Claude Pressac, and how he uses them, to prove that Germans used homicidal gassing chambers for the mass murder of Jews. Maybe this paper will suggest a few questions to you. Why not call the U.S. Holocaust Memorial Museum in Washington D.C. and ask its research department to help you with the answers.
