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
