Took Wednesday off work and attended a seminar at ADFA on footnoting. Incredibly, footnotes account for around 20% of the entire thesis, so this is a reasonable thing to look at carefully. The biggest problem is that attribution isn't enough. They also want you to quote when you use exact words. And they don't want to see a lot of quotation marks, ie they want you saying what others have said in your words. Fine if their words are mostly waffle but tough when dealing with historians who use words honed to a razor's edge. Paraphrasing can easily lead to error. Worse, when you go through later tidying up the grammar, the possibility exists that you will change to the same words.
Every footnote is going to have to be rechecked and there are hundred of them.
