I made a high-quality scan of PAIP (Paradigms of Artificial Intelligence Programming), and worked on OCR'ing and incorporating that into an admittedly imperfect git repo of Markdown files. I used Scantailor to deskew and do other adjustments before applying Tesseract, via OCRmyPDF. I wrote notes for some of my process over at https://github.com/norvig/paip-lisp/releases/tag/v1.2 .

I'd also tried ocrit, which uses Apple's Vision framework for OCR, with some success - https://github.com/insidegui/ocrit

It's an ongoing, iterative process. I'll watch this thread with interest.

Some recent threads that might be helpful:

(Meaning, I have these browser tabs open, I haven't fully digested them yet)

Was technology the right approach here? Is it essentially done now? I couldn’t tell if it was completed entirely.

I can’t help but think a few amateur humans could have read the pdf with their eyes and written the markdown by hand if the OCR was a little sketchy.

It's still in progress! It's looong - about a thousand pages. There's an ebook, but the printed book got more editing.
