According to an article in the star, Google has determined that there are 129,864,880 books.
That's a lot of books!!!
I have 90 that I own on my shelf, 2-3 "out on loan", and another 10 on my shelf/bedside table that I have borrowed from other people. I didn't count any of Dave's books...or my textbooks.... but now that hardly seems like any at all!!
