Sometimes? But for scanning I can use a cheap worn copy as long as the pages are clean.

Most books I would rather have a digital copy. I had four or five book cases full of stuff and it makes moving difficult.

I originally started scanning 20 years ago when it was more difficult to find PDFs of basically whatever you want. Now it is only random old books I find at the used shop or online for cheap and somehow cannot get from archive.org or elsewhere.
