i really don't agree that forgery implies there is a real one the protocols are very frequently referred to as a forgery and similarly for the hitler diaries and countless fake archaeological artifacts the word only implies that something is presented as genuine when it isn't a fake copy of a known painting is a forgery but so is a fake previously unknown painting of a famous artist all dictionaries that i consulted agree e g merriam webster refers to making or copying but i won't argue about this further if nobody else agrees i can also go with fraudulent book which is more informative than fraud and not so soap boxy as lie fraudulent document would also be ok it wasn't first published as a book talk
