Three Fictional Biographies

Why is it that, if we read Poul Anderson's History of Technic Civilization in its original order with the Nicholas van Rijn collection, Trader To The Stars, as Volume I, then "Hiding Place" is the first story to be read whereas if instead we read Baen Books' The Technic Civilization Saga, for the first presenting this longest of Anderson's several future history series in chronological order of fictitious events, then "Hiding Place" is the eleventh installment, not to be found until the very end of Volume I, The Van Rijn Method?

Chronologically, "Hiding Place" is preceded by:

the opening three stories of the Technic History (see A Firm Foundation...);

three previous van Rijn installments, the earliest requiring a rewrite to incorporate it into the future history, the second a full length novel;

a loose "David Falkayn and the planet Ivanhoe" trilogy (Falkayn on Ivanhoe; Falkayn elsewhere; others on Ivanhoe);

a one-off story about Adzel as a student on Earth.

Thus, three fictional biographies, those of van Rijn, Falkayn and Adzel, come together in The Technic Civilization Saga, Volume II, David Falkayn, Star Trader, when van Rijn founds his first trader team, led by Falkayn and including Adzel. The Technic History is anything but a single, linear narrative. To a lesser extent, the same is true in the later Terran Imperial period when one story and one novel recount events occurring elsewhere during the career of Dominic Flandry.
