One of the most productive ways you can handle the transition from paper to digital is by leveraging tools that use OCR (optical character recognition). While it has significant limitations when it comes to handwriting, if you're trying to cut down the amount of paper you have to handle, OCR can make the text searchable without having to do extra work or translations.
I use OCR all the time through OneNote when it comes to managing documents, manuals, mail, invoices, basically anything printed that I can take a picture of. It's been invaluable to me in getting my paper under control. If you're looking to start using OCR, understanding how it works and it's limitations will make the process much smoother. MakeUseOf wrote a great article on understanding how OCR works and how you can put it to use.
