The Dreger paper appears in a high-end peer-reviewed journal.  That makes it an RS.  That Dreger received a prestigious award to expand it into a book.  That makes is all the more solid an RS.  What you personally think about her or the research behind the documents is irrelevant; it is the WP policies that matter.  If you want to argue that both the journal's reviewers and the Guggenheim awards committeemembers were all in error, that is your business.  However, I would caution against making accusations against such committees with no evidence beyond your own suppostions; doing so constitutes a BLP violation. :::
