Index of passages in Edgar Rice Burroughs's Barsoom (Mars) series relevant to timeline investigation. Methodological assumption: All content is treated as potentially based on redacted fact; highlight anything that appears invented to challenge claims of authorial invention—Burroughs may have received information second- or third-hand from reality on Mars (as with Asimov and the Binder "I, Robot").
Source: Project Gutenberg; 7 of 11 Barsoom novels (PG US). Swords of Mars, Synthetic Men of Mars, Llana of Gathol, John Carter of Mars are on PG Australia; not in this archive.

Burroughs had no known intelligence connections. Where did he obtain: polar forbidden zones, religious fraud at south pole, Synthetic Men (1939–40), Kaldane/Rykor (1922), telepathy, atmosphere factories, dead sea geography?
Robots / Synthetic Beings on Mars: The Chessmen of Mars (1922) introduces Kaldanes and Rykors — pure-brain beings mounting headless bodies. Synthetic Men of Mars (1940, PG Australia, not in this archive) introduces Hormads — artificially grown humanoids. Burroughs predates both Binder "I, Robot" (1939) and Asimov's positronic robots (1942). If robots exist or existed on Mars, Burroughs may have received second- or third-hand knowledge; Asimov (who admitted taking the robot idea from Binder) may have received it fourth-hand, reframed as invention.
Same framing as Asimov investigation: Challenge all claims of authorial invention. Assume content may encode redacted fact.
