While it's really cool that this is possible now, this project seems to be a thin wrapper around running Claude. Presumably, someone who wanted to read one of these books could just run it through Claude themselves with comparable results. Sharing some artifact of your own added value, or things you learned in the process, would be more interesting to me than the output.
I can assure you this is not a thin wrapper. Even the public repo of the first workable version of it is not a thin wrapper. You are welcome to try. It is not rocket science, but what I developed would take much effort to reproduce. I wrote an origin story about how I got started: https://aicentral.substack.com/p/pipeline-to-the-past It describes some of the added value and lessons learned.

What I haven't found in either the OP or Github repo is what your background is - software development? astrophysics? paleography? two or three of those? [edit: history of science?] - and what human review is involved. (My apologies if I overlooked anything; I don't have time to read it all!)
