You are a living book; you have chosen to be a living book. You are the last copy of your chosen book in existence. Who are you and why are you that book?
If I were the last of a book I would have to either be a book of history, or a book of medical remedies.
I would choose the book of history because I think of history as a great reference for research and it shows us the backstory that we have as human beings. without history we wouldnt know what we were, or why we were a certain way. However from a standpoint of wanting to be as useful as possible being a book of medical remedies would be extremely useful as everyone could benefit in it in at least some way.
However the question given can be easily interpreted that if you were the last of that specific book, that all other books would remain in their current existence. If that were so, then I would be the most meaningless book I could find, maybe a kids book I find in my box of cheerios. Sure I wouldn't be important, but it would be the best for the world and humankind.
