Overlapping Stories In Two Omnibus Collections

Poul Anderson's The Earth Book Of Stormgate begins with:

"Wings of Victory"

"The Problem of Pain"

"How To Be Ethnic In One Easy Lesson"

"Margin of Profit"

- whereas Baen Books' later omnibus collection, The Technic Civilization Saga, Volume I, The Van Rijn Method, begins with:

"The Saturn Game"

"Wings of Victory"

"The Problem of Pain"

"Margin of Profit"

"How To Be Ethnic In One Easy Lesson"

There are two differences. First, the Saga is the complete History of Technic Civilization and therefore includes the previously uncollected, and also more recently written, "The Saturn Game." Secondly, "How To Be Ethnic..." and "Margin of Profit" are contemporaneous and therefore can be read in either order although I prefer the Earth Book order as establishing the background of the Polesotechnic League before introducing van Rijn.

Stories overlap even more in The Technic Civilization Saga, Volume II, David Falkayn: Star Trader, where there are three sets of characters:

van Rijn in "Territory" and "The Master Key";

the trader team in "The Trouble Twisters" and "Day of Burning";

another bunch of guys in "A Little Knowledge";

van Rijn and the trader team together in Satan's World and "Lodestar."
