Shared Universe Works

This category is for stories written by Harry Turtledove that are shared universe works

A shared universe or shared world is a set of creative works where more than one writer (or other artist) independently contributes a work that can stand alone but fits into the joint development of the storyline, characters, or world of the overall project.

These shared works should not be confused with pastiches, as they are usually more substantial than mere imitations, and are often earnest attempts by Turtledove to contribute to the overall body of work of another author.
