Ah yes, the source recommend by Stormfront.
For knowledge of the Holocaust, which is an extremely broad subject (involving the majority of the countries of Europe, intricate political and policy considerations, WWII and its course, different governments, languages, cultures), 50 books is really a very small number. My first reply to this claim of Jim's was moderated, I am guessing for sarcasm, as I was unimpressed. So I'll just say that I own somewhere in the neighborhood of 1000 print books about the Third Reich and the Holocaust (I have read most but not all of them and keep working away at the unread titles) and many uncounted digital books, among these a number of the Holocaust Handbooks, which turn out to be a very dubious source for the history of the Holocaust (Holocaust Controversies does the best job of demonstrating just how dishonest and shoddy these HH books are).
I probably own close to 50 titles on just Warsaw and the connection of Warsaw ghetto to Treblinka (as I'm not at home I am just guessing - it is certainly dozens and ditto for the Ostland, Lodz, Auschwitz and other topics), or, to go in a different direction, another 50 on the development of Nazi Judenpolitik. My collection - and reading - pale when compared to a scholar like Nick Terry, who posts here.
Scholars in this field probably read 50 books on the Holocaust every few months, my estimate based on bibliographies and so on, so Jim's owning 50, mostly HH books on the Holocaust doesn't stand him in good light against people who are actually knowledgable about the period and events, let alone scholars of the period whose work encompasses the secondary literature and research in the archives.
Now, as for HDenier, where is that list of books he's spent good money on and the cross-check of what he has/has read against the 12 recent books I listed?
