That's awesome what a great idea! Nice Pratchet's books and the Hitchhikers series are great! Hope you find some stuff you enjoy. Getting back into reading has been one of the best things I've done in years and has helped my life in a lot of ways. I found what helped me get back into the habit was just keeping something to read with me when I had time to kill like waiting for food or an appointment, reading on my work breaks to give my eyes a rest from screens, and reading around an hour before bed to help my sleep quality. You'll be surprised how fast you'll go through a book I usually would end up reading about 30 mins to 90 mins today. Also if you don't like something by like 100 pages in just drop it. Trying to force myself to read things to the end I wasn't enjoying killed my desire to read. By dropping books I actually ended up reading more than before. I hope you enjoy some wonderful stories! :)

A lot of Danish libraries have ebooks, but its a proprietary system and requires a compatible ereader. That basically means it only works for kindles.

I haven't used it at all, I don't bother
