:Many thanks for the offer. 
 :If you have found any particularly bad use of sources, please let me know where and I can add them to the list I'm collecting. Don't worry too much about finding the exact diff or location in the history; but if you can identify any claims that are not supported by the reference given, that would be good to know. A lot of references can be checked via books.google.com or scholar.google.com. If you can't get access to a source, let me know: I can probably get hold of it here without too much trouble. 
 :As for taking this to the administrators, I have no idea what the best thing might be. I've been asking various more experienced editors for their opinion. We shall have to see what people think. 
 :All the best. –
