If any of the remaining Castles com cites are also supported by another cite then remove the Castles com one Add a Further reading section and put the Castles com link there Well that s what I would do anyway I know that the webpage is supposed to be a transcription but well how do we know that it is an accurate and full transcription There were a lot of people with experience who chipped in with comments as this article developed all of whom were pleased with the outcome as far as I can recall It does not need any big reworking Oversourcing can be an issue but I think that in this instance it was pretty much all needed unless the decision was taken to rely primarily on Castles com Of course no article is ever finished
