If you wanted to find out how many different books have ever been written, you’d probably start with a Google search. In 2010, the tech company came up with the answer. According to Leonid Taycher, a Google software engineer working on the Google Books project, that number is 129,864,880. The search began with the ISBN cataloging system, but many other programmable searches were required in order to come up with a more accurate count.
A bit of light reading?
This isn't true because there are millions of people that have written books and paid to have them printed, rather than go through a company. Some of these books are amazing and I have read one that was 1,000 pages long. So their total of books is only the amount that big businesses printed, right?
Also, why would they count a book as two if it has a different foreword? That makes no sense because the story is what should be counted, not what other people say.
