Definitive Proof of the Existence of Doctor Who

Ancient Man: A Handbook of Puzzling Artifacts by William Corliss is the best, but it’s dated and very rare. He also has a series called Archaeological Anomalies. It’s mostly straight-up reports of things that don’t make sense, or things found where they shouldn’t be. He’s not an “ancient aliens” wignut: just a Fortean intrigued by anomalies. Corliss was a physicist who selected only material from academic journals. He died a couple years ago.
