Callahan's Place is the neighborhood tavern to all of time and space, where the regulars are anything but. Pull up a chair, grab a glass of your favorite, and listen to the stories spun by time travelers, cybernetic aliens, telepaths...and a bunch of regular folks on a mission to save the world, one customer at a time. Callahan's Crosstime Saloon contains the following stories, virtually all of which were published in Analog Science Fiction and Fact: • "The Guy With the Eyes" • "The Time-Traveler" • "The Centipede's Dilemma" • "Two Heads Are Better Than One" • "The Law Of Conservation of Pain" • "Just Dessert" • "A Voice is Heard in Ramah..." • "Unnatural Causes" • "The Wonderful Conspiracy"
Spider Robinson's "Callahan's Crosstime Saloon" series had a story towards the end that blew my tiny little teenaged mind back in the 90's.
Octavia Butler, of course. Xenogenesis.
"Shared pain is lessened, shared joy increased." It's really that simple, folks.
Some more good ones: Ilium/Olympos - Dan Simmons Centuries - A. A. Attanasio Callahan's Crosstime Saloon - Spider Robinson Signal to Noise - Eric Nylund
I also recall that there was a little fandom controversy at the time where people complained that it wasn't really a time travel story and what was this jerk Spider Robinson trying to pull anyway!
