I came across your blog while doing research on vampires, and I admire and appreciate your scholarly work -- the accuracy, detail, and depth that you give the subject. I also found your English translation and commentary of the report Visum et Repertum extremely helpful (thank you). You also mentioned that the original manuscript was stored in the archives in Vienna, and my questions are: are these archives available online (I did a search but couldn't find it)? And how did you manage to obtain a photo of the report?
I don't think you can find these manuscripts online. The archives storing some of the most important documents are located in Vienna: The Austrian State Archives which are located at two addresses in Vienna, one of which is shown in the accompanying photo.
