Google estimates that there have been created 129,864,880 books as of this week, see the post for a definition of book by Google.
Looking at the world population as of today (7,032,852,000) if the book authorship was shared equally in the world each person would be responsible for 0.0184654647 of a book. Now clearly most of the books would actually have been published prior to the current population being born, and there have been over 100 billion people born thus far, so if we add another 0 (and some change) we find that each person is responsible for 0.00122476079 of a book (note most authors actually write more than one book, and so the figure is more realistically 0.0007 for everyone else but we won’t go that far)
So have you contributed your 0.001% or so to the world’s books? If not, why not?
yep, me 4.62%
