Trivia / A Canticle for Leibowitz

• Sequel Gap: The book was a standalone novel for 38 years until it received a sequel in 1997.
• Technology Marches On:
  • At one point, Abbot Zerchi turns off a television with such anger that he breaks the knob off. Possibly justified in that this occurs almost 1800 years in the future, after technology has re-emerged.
  • Anti-ballistic missile systems started emerging in the 1970s, more than a decade after publication. The Asian Coalition would have to be very sneaky or very lucky to surprise-nuke Texarkana if anything like NORAD was re-emerged. On the flip side, even today low-altitude cruise missiles are tough to detect and neutralize.
