Seen in "Entangled" (Episode 4 of Season 10), this book plays a bit part in the plot. The dominoes on the cover give the co-ordinates (2 5, 2 3, 1 1) of the ERRA space station. A real book, published around 1972, both the softcover version (seen at the start of the episode - shown above) and the hardcover version (seen at the BEGG camp) are used in the episode.
