Ask HN: Digitize a Library?

My father, who was an homme des lettres, recently passed away, leaving us his huge collection of books. I'd like to make digital copies, but running them through a flatbed scanner would take too long. Are there faster ways? Eg. recording a video of flipping through the book's pages with a software extracting the individual pages from the book? OCR would be nice to have but not necessary. TIA!
