Time Charts And Chronologies

I suppose that the omniscient narrator who is the most abstract and distanced from us, the readers, is the compiler of future history time charts or chronologies in:

Robert Heinlein's Future History

Poul Anderson's Psychotechnic and Technic Histories

James Blish's Cities In Flight

Larry Niven's Known Space future history

Also, one of Isaac Asimov's successors compiled such a chronology in an add-on Foundation volume.

There is no personal voice or input in any of these compilations but they can hint at ramifications that are beyond our ken like humanity moving towards its first mature culture at the end of Heinlein's seminal Time Chart. We do not see this in any of the stories but we know that the future continues beyond the end of any future history even in Cities In Flight where two universes end but others begin.

Poul Anderson's characters reach the end of this universe and the beginning of another both in Tau Zero and in The Avatar.
