I'm writing an essay that must be referenced in the Harvard style and have a fairly complex question. If anyone is familiar with the in's and out's of the systemm and is willing to let me pick their brain, i would be most grateful.
My question: I wish to directly quote a quote within a book. Not only this, but the author of the book has claimed his source (of the quote) to be 'Private Information'.
How would i correctly go about citeing this?
