   “Wrong-Way Street”
by Larry Niven
First publication: Galaxy, Apr 1965

Ever since an accident that killed his eight-year-old brother, Mike Capoferri has been interested in time travel, and now he thinks one of the alien artifacts found on the moon is a time machine.

 Mike was a recent but ardent science-fiction fan. “I want to change it, Dr. Stuart,” he said earnestly. “I want to go back to four weeks ago and take away Tonys Flexy.” He meant it, of course.

   “Rotating Cylinders and the Possibility of Global Causality Violation”
by Larry Niven
First publication: Analog, Aug 1977

A mathematician named Quifting has a way to use a time machine to end the war with the Hallane Regency once and for all.

 Did nobody ever finish one of these, ah, time machines?

   “The Man in the Pink Shirt”
by Larry Niven
First publication: Analog, Nov 2012

Hanny Sindros, a writer, travels back to meet John W. Campbell, Jr., and talk about whether the Nazis might gain something from Cleve Cartmill’s atomic power stories.

 What if these German spies see that Astounding has suddenly stopped publishing anything about atomic bombs? What would they do? Theyd think we were hiding something.

Additional Adventures (without Time Travel)

I often see potential time-travel stories that, alas, have no time travel. I track them, so that I don’t process these same chronotypical stories over and over in a time loop of my very own.
