You can purchase a copy of this book for yourself! There are several editions available:

This is the version I'm most familiar with - it's from Shambhala Publishing's "Pocket Classics" series. To be honest, I don't have a lot of pockets that this will fit in, but it is a nice size and shape, especially for flipping through randomly, seeking advice for whatever your current situation may be. (Much more helpful than the Magic 8-Ball.) $6.95 US Buy it at Powell's Books
Another nice version from DoubleDay. Bigger than Shambhala's, but probably still emininently flip-through-able. $11.95 US Buy it at Powell's Books
