## Is this the true first?
This is a revised and expanded version of the 1969 novel Grimm's World, retitled and given a new opening section drawn from the novelette The Barbarian Princess; the Baen 1987 paperback is the first edition of this revised text and the first appearance under the Tatja Grimm's World title.

## Telling it from reprints & book-club editions
None; as a paperback original there is no book-club hardcover for this text, and later Tor reissues are separately identified by their own imprint and ISBN.
