:::As discussed in stultifying detail at Wikipedia:Reliable_sources/Noticeboard#One topic publishing house acceptable as RS?, the big problem with this page is with too many self-published and not enough reliable sources. Self published sources are sufficient for noting information that does not conflict with better sources. SPSes lack the power, however, to go toe-to-toe with more scholarly sources. The issue here is that so many of the sources are self-published. I am guessing that your "one of the most respected and known historians" is Cherie Kropp whose work is all self-published. At any rate, it's a source, and should be noted at the same time as you add the information. We don't add contrarian text to the main article for the purpose of discussion on the talk page; we add that text to the talk page itself.
