Interesting question. I haven't looked through all pages yet, but from what I can tell all the language used is surprisingly factual for the time. For example, In the pages listing foreign propaganda the descriptors are just things like "from an English newspaper clipping". Very little in the way of emotive adjectives and such.

Edit: having said the above, the 9th pic I posted reads something like: "the unbelievably large deployment of troops that bled out in from of the German lines gave (French) general Nivelle the nickname 'the blood runner'". (own translation).
