Having discussed Isaac Asimov’s The End of Eternity last time, I thought to move forward a decade or so and look back at a similarly recomplicated tale of time travel and time paradoxes: Robert Silverberg’s 1969 novel Up the Line.
Silverberg has written numerous novels and stories concerning time travel (there are photos of some of them lower down on this page), but there are different kinds of time travel stories, and Silverberg has focused on only a couple. Some involve simple trips into the future (Wells’ The Time Machine) or past (Silverberg’s own “Hawksbill Station”) with or without return tickets; others involve interfering in history and creating, inadvertently or intentionally, alternate timelines; others involve preventing such alternate timelines; and so on. Of Silverberg’s time travel stories, Up the Line is an example of the most complex type, about the potential paradoxes inherent in time travel, how to avoid them or deal with them. And so it’s his one novel most directly comparable to Asimov’s The End of Eternity.
The book was published as a paperback original by Ballantine Books, during Silverberg’s prolific middle period, in 1969. So far as I can tell, it has never been reprinted on its own in hardcover. (Per isfdb, it’s included in a 2003 Book Club omnibus with three other novels, and a 2011 Subterranean press omnibus with two other different novels, both of these omnibuses hardcovers. The most recent individual reprint of this novel is an ibooks trade paperback in 2002. None of these three volumes are available in new condition except at exorbitant prices.) So page references here are to the original Ballantine edition, last reprinted in 1988.
