The books in the series were written by several authors. It consist of five collections of short stories and three collaborative novels. Each volume takes place in roughly chronological internal order, but starting in different time periods (for instance, CoDominium: Revolt on War World, chronologically the last collection in the series, is set during the earliest years of human settlement on Haven). Blood Feuds incorporates material that originally appeared in the short story collections. John F. Carr rejuvenated the series with the publication of War World: The Battle of Sauron, by Carr and Don Hawthorne (Pequod Press, 2007). The series is starting over with the publication of War World: Discovery (2010), edited by John F. Carr. The new books will be published in chronological order, with Discovery providing background on the first surveys and colonization. The new volumes include fresh stories intermixed with ones from the original series, providing a more complete look at the War World universe.
