The Alternate Asimovs

Blurb

The Alternate Asimovs is a collection of early science fiction drafts by American writer Isaac Asimov. Asimov mostly threw away early drafts. Just a few survived and were included in this anthology.
It consists of three items:
Grow Old With Me, the original version of the novel Pebble in the Sky, never published in this form
"The End of Eternity", an unpublished 20,000 word novella that was extensively revised before appearing as the novel The End of Eternity
"Belief", two versions of a short story
