  :Tourskin, I am concerned about your approach to sources.  All the sources you have listed are meant to be introductions, or their scope is far too vast to be useful for such a specific battle. Madden's book is a good start but it is also meant to be an intro to the crusades in general; it is very short and doesn't say much about Nicopolis. And where are they getting their information from? Have you looked for any primary sources? I understand that foreign languages are a problem (I can't read Turkish either!), but you shouldn't discount research just because it isn't in English. I also wouldn't put my faith in random websites like geocities or about.com. It's great that you are trying to help, but I worry that the article might actually suffer in the end.
