Second Series?

There are seventeen additional Dune novels by Brian Herbert and Kevin J. Anderson and there is also a Second Foundation Trilogy by Gregory Benford, Greg Bear and David Brin. I think that this is precisely the wrong way to extend a future history series. I would not want to read a Second Polesotechnic League Tetralogy, a Second Young Flandry Trilogy or a Second Captain Flandry Series etc by other authors. There are many other potential extra stories in Poul Anderson's Technic History but probably they cannot be written by anyone. I would have welcomed a lot more by Anderson himself but that is no longer possible.

The Technic History universe extends into the past histories of the Chereionites and of The Sky Book Of Stormgate. Various one-off characters could have become series characters. The future extends indefinitely beyond "Starfog." As Tolkien wrote of his Trilogy, "It is too short."

But, to reach this conclusion, we have to read and reread the Technic History and, when we have done that, we appreciate how long it is.
