Back to Russia I had two favorite books: one was called "The history of the USSR in IX-XIII centuries" (yes, of the USSR!), and the second one was "Tables of prime numbers from 2 to [some 10-digit prime number I don't remember]"
Actually, there exist something more weird than that: a book called "A Million Random Digits with 100,000 Normal Deviates" published by the RAND corporation. Only $81 on amazon.com.
Don't ask me how I found it. :-)
