Not just any book, the $81.01 Million Random Digits with 100,000 Normal Deviates on Amazon is exactly what it sounds look, and is actually quite popular, believe it or not. One reviewer says: “Such a terrific reference work! But with so many terrific random digits, it’s a shame they didn’t sort them, to make it easier to find the one you’re looking for.” Product page. Here’s what user Chris has to say:

I took a class in statistics in college. I used this book to help me select random phone numbers for a poll I was conducting for my class project. One of those phone calls was answered by the woman who is now my wife. We’ve been happily married for ten years! Thank you, RAND.
