Under the Moons of Mars: A History and Anthology of "the Scientific Romance" in the Munsey Magazines, 1912-1920 (79 page)

Burroughs wrote Balestier asking what his status was with the Munsey magazines, now that Davis was gone. He received a reply whose finality was underscored by the lines: "We are overstocked."

A great era in the development of the Munsey adventure pulps had ended, and a new one was beginning, but the past actions taken by Frank A. Munsey, Robert H. Davis, and Edgar Rice Burroughs were destined to shape the entire history of pulp-magazine publishing and echo in the works of science fiction for its foreseeable future.
