Time Patrol And Island In The Sea Of Time
The points of comparison have been:
the reality of the past;
the absence of coffee in the past;
how to deal with shamans;
battles of the gods;
attempts to prevent history from being changed;
dreams of horned men;
pre-Columbian North America;
small town American time travelers.
Far from the later work imitating the earlier work, both are, in the true sf tradition, different original answers to a common basic question: what are some of the imaginable consequences of time travel with causality violation?
Would time travelers find it necessary to organize a police force to prevent causality violations?
Suppose not just an individual time traveler but an entire town were to be transported into the prehistoric past.
Another comparison that has just hit me: James Blish has entire cities crossing interstellar distances faster than light.
