MCU Canon
Primary sources for this list are the Marvel Studios movies themselves, viral promotions, and in future the Marvel One-Shot short films. Secondary sources are from the Home Release extras (Deleted Scenes, SHIELD Data Vault etc), the comic and novel adaptations, and the expanded universe comics. Tertiary sources are for anything else said to be within the films universe; unless confirmed otherwise (currently Captain America's tie-in video game which comics writer Christos N Gage stated as being in canon).

How you can help
I need your help here people; being only one man and going through all this content, I am bound to miss something. So please help verify and make sure this resource is up to date with everything we currently know about the MCU.
Quick note (as i am guessing this will be a big moan for people): Yes i have included the Captain America video game. This is because the writer has stated it is set within the films universe and had to make various big changes to the storyline to keep it inline with the movie (Falsworth not getting turned into UJ, Zola not giving up on his real body etc).
On the subject, I don't know if the Thor: God of Thunder video game is considered in canon like the Captain America: Super Soldier game or loosely-based like the Iron Man games, and being while since i played the Cap game i am not sure if i missed out on some of the Zemo family.
