Personally I do either or, but doing both may work for you. Through my job I’m somewhat familiar with literacy studies etc. It seems to be the case that especially for persons with dyslexia, listening and reading at the same time strengthens the reading skills and makes it easier to concentrate.

Two things: I almost always listen at 1.5 speed, my brain just can’t take the normal (super slow imo) speed. And then I usually do something else such as household chores (dishes, laundry etc.), knit or take a walk with my dog.

I have always had a hard time concentrating on just listening. Back in the uni I during lectures I doodled, knitted or took notes, and I do the same now if I’m attending a work related webinar etc. So same goes for audiobooks and podcasts.

Really depends on where you are. I guess most commenters are from the US. Where I’m at (in Europe) public libraries are huge buyers of books, and on top of that authors receive compensation for library loans from the government. Author does get most out of selling a physical copy of a book, but libraries are a part of their income as well.
