I was looking over the extras on the Iron Man 2 blu ray, and there are some extensive Shield files to go through. Still, I couldn't help but think that they could have easily laced that stuff with far more references to Marvel history and characters... basically, no newspaper article or journal scribble references any character that hasn't already appeared. How easy would it have been to reference some WWII scientists like Horton, or some modern ones like Pym?
Also, I found it odd that they had files on most of the Hulk characters, but aside from a mention of Sterns in the Abomination's entry, nothing on him. The location of every villain that has appeared in a Marvel produced film is listed as "Classified" (including the ones that apparently blew up). That goes for Justin Hammer as well, although they maybe just chose "Classified" so as not to conflict with any future attempts to reuse most characters.
