Northwest of Earth is a near-exact duplicate of Shambleau and Others, each containing a mix of Northwest Smith and Jirel of Joiry stories.
The two books don’t quite exhaust the two series, although half the omissions started as fanzine fodder. The missing stories are:
• “Nymph of Darkness,” co-written with Forrest J. Ackerman (Fantasy Magazine, April 1935, reprinted in Weird Tales, December 1939) [Smith]
• “Quest of the Starstone,” co-written with Henry Kuttner (Weird Tales, November 1937) (Smith and Jirel]
• “Werewoman,” (Leaves #2, 1938) [Smith]
• “Song in a Minor Key,” (Scienti-Snap, February, 1940) [Smith]
From this distance it appears even stranger than the Gnome norm that Greenberg twice mixed the Jirel and Smith stories rather than devoting a volume to each, certainly what most fans would have preferred. He probably had a plan in mind, according to a review of the book by L. Sprague de Camp in the August 1955 Science Fiction Quarterly.
Greenberg’s intention was to end the series with the story in which both Jirel and Northwest appear: “Quest of the Starstone,” (from Weird Tales, Nov. 1937, with Henry Kuttner). But the new volume lacks this story… When, feeling swindled, I contacted the publisher with these outrageous omissions, I learned the fault was that of the author herself. She had decided, forsooth, that these stories were not good enough for hard covers!
J. Francis McComas reviewed the book for the December 12, 1954 New York Times Book Review:
Once again the indestructible Northwest Smith blasts his way through various interplanetary underworlds and once more Jirel of Joiry pits her beauteous body and sharp sword against the sorcerers whose magicking disturbs the peace of the warrior maid’s realm. Which is about all that needs be said concerning this second volume of C. L. Moore’s youthful chronicles of this incredible pair.
