Not a DIY kit, but in case LibGen is insufficient and you need a commercially available solution, ScanSnap scanners have a model for this purpose. https://www.pfu-us.ricoh.com/scanners/scansnap/sv600 https://www.pfu-us.ricoh.com/scanners/scansnap/sv600 The software has automatic page-turn detection (so you don’t have to repeatedly press the scan button); has page-curve correction and deskew; and automatically removes fingers/thumbs from the image, in case you need to hold the pages down. Neat! Like another commenter, I used 1dollarscan to digitize many books (to save space) but I agree that that process was more expensive than expected (and destroyed my physical books, which I have come to regret). If I had known about the scanner I just linked to, I probably would have invested in one instead. Off-topic, but apparently Ricoh has acquired the ScanSnap brand from Fujitsu. (News to me, at least.) But unless Ricoh has changed something, in my experience it’s hard to go wrong with the ScanSnap brand for personal scanning needs. (I have no affiliation with the companies or brands mentioned.)
