So I'm looking for recommendations about book scanners (Google search gave me some ideas about brands and actual features, but I couldn't find recommendations from people with actual experience)
Thanks.
It is tolerable for a small number of books. Scanning a thousand pages is an ordeal that you will not be keen to repeat.
I spent a day trying different software. I don't remember for certain which software I used, it may have been naps2.
Other than that, have you checked your local library if they have a book scanner? No need to buy your own ...
