::::The figure "6 million" is the "most commonly cited" (see the article for the Holocaust). The sources on that page (all with proper references to books, websites, encyclopedias, etc) provide a wide-ranging spectrum for the number of murdered Jews (i.e. "4.2 to 4.5 million in The Final Solution (1953)," "5.95 million from Jacob Lestschinsky"). Any claims you make in an article should be similarly supported by external sources. —·
