Time machines

The notion of traveling forward or backward across history—changing the events of your own life or those which came before you or those that have yet to occur—starts here with Edgar Allan Poe's "Three Sundays in a Week" and Rudyard Kipling's "Wireless," progresses through the years with past masters Isaac Asimov, Ray Bradbury, and John W. Campbell, Jr., and finishes with contemporary science fiction by such writers as Larry Niven, Harry Turtledove, Jack Finney, and Rod Serling.
