Here's what I did, which works much better than phone apps or scanners. Mount a digital camera on a tripod and bring a couple lamps over for strong uniform lighting. Turn the page, take a picture, turn the page, take a picture. You'll go through a 100 page notebook in 10 minutes (not an exaggeration). There are better quality ways to digitize documents, but I don't know of anything cheaper and faster.

Even some of the best quality scanners mimic this technique

I don't have a link handy, but this is what Google did when digitizing books for Google Books back in the day. They had a hardware setup that I believe had foot pedals to snap the picture, but human hands are (were?) still the best page turning technology they could muster. There was also software to make the image of the page appear flat, rather than curved as most books appear when laying open.

  yeah! I just remembered there were some news articles about hands appearing in some of the scans

  > There was also software to make the image of the page appear flat, rather than curved as most books appear when laying open Yes, they projected a grid (using red light, I believe) on the page so they could compute the curvature to re-project the image as "flattened".

  Interesting. I had been led to believe that Google used a linear book scanner towards the end of the big Google Books library scanning project. It looks like this may have been an internal prototype that wasn't necessarily used for large-scale scanning opert https://www.youtube.com/watch?v=4JuoOaL11bw&feature=emb_title https://www.youtube.com/watch?v=4JuoOaL11bw&feature=emb_titl... https://hackaday.com/2012/11/16/google-books-team-open-sources-their-book-scanner/ https://hackaday.com/2012/11/16/google-books-team-open-sourc... https://code.google.com/archive/p/linear-book-scanner/ https://code.google.com/archive/p/linear-book-scanner/ https://linearbookscanner.org/ https://linearbookscanner.org/

There's a guy that build a high end DYI book scanner using this same idea. He sells them prebuilt every once in awhile as well. http://diybookscanner.org/archivist/ http://diybookscanner.org/archivist/

  On the DIY Book Scanner forum, I saw the TIFLIC scanner, which I plan to build. A build post: https://evilgeniuschronicles.org/2018/09/25/my-build-of-the-tiflic-diy-bookscanner/ https://evilgeniuschronicles.org/2018/09/25/my-build-of-the-... A demo from the creator's about 1 minute in: https://vimeo.com/213003462 https://vimeo.com/213003462 It feels simpler to build and it takes up less room.

This seems similar to the rocketbook, but more permanent and less reusable.

Fujitsu ScanSnap SV600 is a hardware setup for such scanning.
