A Second EARTH BOOK?

At the mid-point of Baen Books' The Technic Civilization Saga, Volume III, Rise Of The Terran Empire, Hloch concludes The Earth Book Of Stormgate and Donvar Ayeghen, President of the Galactic Archaeological Society, introduces an account of the Founder of the Terran Empire. Ayeghen refers to Manuel's Empire as the First so he writes at least during a Second Empire if not later. Ayeghen might have compiled an Earth Book Of Galactic Archaeology to "span, illuminate and complete" the history of the Terran Empire as Hloch had done for the Polesotechnic League period. I imagine a commentary by Ayeghen introducing a film of The Game Of Empire. See the previous post. Eventually, human civilizations spread through several spiral arms of the galaxy so that a third Earth Book would no longer be comprehensive enough. By that time, civilizations have become "post-Technic" although not post-technological.
