One for alfaguru:

Zetetic astronomy. Earth not a globe! An Experimental Inquiry into the True Figure of the Earth: Proving It a Plain; Without Axial or Orbital Motion; And the Only Material World in the Universe! by "Parallax" (1865)

And I don't just mean looking for accidentally scanned fingers.

So go find me some weird books and report back.
