Inmate numbers for Nazi concentration camps
During the Holocaust, did all concentration camp inmates have their numbers tattooed on their bodies, or was this only done at Auschwitz-Birkenau? More specifically, was this done at the Hinzert and/or Natzweiler-Struthof concentration camps as well? 2601:646:8E01:7E0B:B167:959E:4F51:222F (talk) 08:02, 19 May 2017 (UTC)


 * There is an article on this - Identification in Nazi camps which clearly states that not all camps used tattoos. Bear in mind also that identification numbers only applied for those being held in camps for a period of time: in the extermination camps there was often no record of who went to the gas chambers, and no numbers were allocated to those who were going to be murdered immediately. I can find no specific references to the two camps you named. Wymspen (talk) 11:27, 19 May 2017 (UTC)

site for book comparison of same title
Is there a website for comparing books with the same title but different editions like 10th edition of Understandable Statistics and 12th edition of Understandable Statistics, both written by Charles Henry Brase and Corrinne Pellillo Brase? I am asking this because I want to see if there are any differences between those two in terms chapters, questions, sections and etc. Donmust90 (talk) 23:01, 19 May 2017 (UTC)Donmust90Donmust90 (talk) 23:01, 19 May 2017 (UTC)


 * I sincerely doubt it, since it would involve a copyright violation, unless the publishers themselves chose to provide such a service. Often the preface of a later version will say what has been changed in a general way.  The 10th Edition of Fromkin and Rodman (the standard intro to linguistics textbook) begins with such a preface, but nothing concrete is mentioned, just that some chapters have been moved, added, rewritten or expanded.
 * If your concern is for a class you are taking, I used to save hundreds a semester by asking the professor if I could use, say, the 4th edition, rather than the 6th. The normal response was fine, just as long as I could get a copy of any material assigned that was not in the older edition.  Usually the only difficulty I had was the page numbers didn't match. μηδείς (talk) 00:17, 20 May 2017 (UTC)
