Companion Volumes

Before Baen Books collected Poul Anderson's History of Technic Civilization as The Technic Civilization Saga, compiled by Hank Davis:

the van Rijn series ended with Mirkheim and the Flandry series began with Ensign Flandry;

between Mirkheim and Ensign Flandry were two companion volumes, The People Of The Wind and The Earth Book Of Stormgate;

the Earth Book contained twelve previously published works with twelve newly written introductions and one newly written conclusion;

the twelve previously published works are set earlier than The People Of The Wind whereas the thirteen newly published passages are a sequel to that novel;

eight of the twelve previously published works complete the history of the van Rijn period;

of the remaining four, two are set earlier than van Rijn and two later.

The Technic Civilization Saga presents the entire Technic History in chronological order of fictitious events although this means that twelve later written introductions and one later written conclusion are presented before the novel to which they are an extended sequel. The best way to read the History is to refer to the seven volumes of the Saga together with the Earth Book as a separate volume. The compilation and publication of the Earth Book by Hloch on Avalon is itself an event in the History occurring after the Terran War described in The People Of The Wind. Thus, "Margin of Profit," the earliest van Rijn story, can be read both as an earlier installment of the Technic History series and as a later disclosure presented by Hloch centuries after van Rijn's death.
