FineReader beats anything else I have used. 300 page books can be done in a reasonable time. I have done a number of PDF to HTML with pretty much success.

The only thing is that each pdf shows differently .....
Is there an optimal (good???) set of options and other settings? For instance Font Style and Symbol Table are a real PITA.
Maybe someone who is an expert could publish a FineReader to HTML/ePub
for Dummys!
