Every name and title is referenced to Italian encyclopedias, and the Italian Version of Wikipedia. Everything else is in black and white in Cardinal Antonio Samore's .Lo Stato Landi," 1983 referenced from the Vatican archives and the ADLP Library. IF you are questioning The Cardinal and The Doria Pamphili Library good luck. It is all cross referenced to multiple sources. !st If you cant read Italian use Goole translate, same for Latin. Every Vatican source is referenced in Samore's book from 97 books documents from the Secret Vatican Archives. "non est argumentum ad hominem"  Oh just in case. Stop attacking the messenger. Do your job and read the reference material. Samore's book is not questioned by anyone it is referenced from over a hundred Vatican sources. Find someone who can read Italian and Latin. Encyclopedia Britannica has accepted these materials for and article to be published in next edition. They did there homework.107.77.76.121  

 References to Wikipedia (English, Italian or any other language) are not considered reliable sources because, as we see, anyone can edit and change the information. We need better references than that. The other references are valid, and I'm not questioning them. What I am questioning is the need for an article on the Landi State separate from the article on the House of Landi which already covers the topic of the Landi State in as much detail as is needed, given the obscurity of the sources. As for accusations that I have "attacked the messenger", please point out what I have said that is any way an ad hominem argument.  ChatMe!ReadMe!!
