You have probably been pestered by one of Life's Persistent Questions: How many books have been published throughout history? Before we can answer that, we first have to answer the deceptively simple question, what is a book? Google Books (a Google-sponsored project to digitize every book, thereby having all knowledge in a single database!!) defines a book as "a tome is an idealized bound volume."
Well, be that as it may, let's have a drum roll, please. As of a few days ago, the answer is 184,021,533 books. We bridge players as a group are also big readers. I wonder how many of those we've read as a group? Luckily you won't have to search any books for today's quiz answers... we've got them for you. Today we're looking at opener rebids. Ready?
