A fixup, from stories copyright 1963 to 1965.
The council of the first generation ship, going out to colonize elsewhere, is debating what to teach their children about their history. In the course of the discussion, they tell stories of major turning points in their history, which some of them experienced in person and others at least heard first-hand stories from.
This seems to me to have stood up pretty well. It was fun to read.
