Are the Man-Kzin Wars books considered canon?
The majority of the stories are not considered to be “Canon” as with the exception of four stories (“The Warriors” MKW1, “Madness Has It’s Place” MKW3, “Choosing Names” MKW8 and “Fly-by-Night” MKW9); they have not been written by Larry himself, they should be regarded as powerful extrapolations of the possibilities of the wonderful playground which Larry has created.
