Duplicate decision #1621

The Gods of Mars

Approved Unique 95% confidence · llm:qwen3.5:9b

Historical decision. This evidence came from index version 233 and is no longer actionable.

Why this decision was made

The titles differ significantly ('The Gods of Mars' vs 'Swords of Mars'). While both feature John Carter and Dejah Thoris on Mars by Edgar Rice Burroughs, they are distinct novels in the series with different plots. The high title score (85) is misleading due to shared keywords ('of', 'Mars') but does not override the clear difference in primary nouns ('Gods' vs 'Swords'). According to policy, these are distinct volumes.
