Thanks for the responses. I guess it's just a nonfiction book about (Subject)
I seem to be throwing people off about what i'm asking by not including the intent of the question. so, just in case:
I was just curious after that discovery channel guy. they say he had a manifesto like other high-profile terrorists.
With society being the way it is, if it was found in his house, someone would likely try to make money by publishing it. if it was short it would go in a magazine, if it was long, maybe it would be a book.
But how would that be marketed? where would they file it? are delusions fiction? what if i wrote the manifesto of captain underpants? where would that go?
It's a personal reflection, that's why i though maybe memoir was the closest genre.
just curiosity...
