I am seriuos!!! Should we add 6C0?
I myself do not know for sure, but it seems to me that we should.
I believe that it should count too unless the question specifically states that at least one book is taken. Having said that, I would be inclined to use language that make it clear what to do if my intent was not to be too tricky.
