Also, if you want to verify for yourself what they say, try using the search strings visible in the previews (despite the fact that the pages are not) in Google.  Somehow, going to the site from google allows you to see the pages.  I had to do that to verify the Age of Reason quote.  My search string in that case was, "Giulio Cesare Vanini strangle age of reason" which produced the source in question as result #1.
