Our university library has a high performance book scanner. Maybe yours has one too. It costs like 1 Cent per 10 Pages, but it's so fast it might be worth checking out if yours has one too. You can extract then the text from the images with tesseract. There are some ready tools that will do this for you to make the PDF searchable
How does it flip between pages?
You do by hand, but it goes very fast. It's like a table, you lay it open (text upside), it scans, you flip it scans. You don't have to open/close anything. Just flip like every second. So for a book with 120 pages you would need like 60 seconds
Usually I think of scanner like a photocopier, this sounds more like it takes a picture?
Well a photocopier takes a picture too ๐
You know what I mean. So it's more of a camera than a scanner?
Well it still has this Bright light like advancing. But the sensor is like 1m above the table. Honestly I don't know if this makes it more a camera or a scanner
My old uni library has 2 of those too. It's basically a fixed camera, but the table you set the book on, has a sort of negative nook that lets you level out the book. So no matter on which page you are, the pages on the book will be on the same level.
