Omnibus Collections

"Operation Afreet," "Operation Salamander," "Operation Incubus" and "Operation Changeling" were collected as Operation Chaos;

Operation Chaos and Operation Luna were collected as Operation Otherworld;

Three Hearts And Three Lions, Operation Otherworld, A Midsummer Tempest, "House Rule" and "Losers' Night" could appropriately be collected although without an "Operation..." title;

if that were to be done, then Master Merchant Nicholas van Rijn would figure in four omnibus collections because he cameos in "House Rule" and is also a major player in the first three of the seven volumes of The Technic Civilization Saga.

The Technic Civilization History is a hard sf future history linear series whereas the works that would be collected in the proposed additional volume are fantasies set in three alternative histories and in one inter-universal venue.

It is to be hoped that such volumes will be published as part of a Complete Works of Poul Anderson.
