You're right, I would be surprised if you're including people of my generation.
My family (me, mom, grandma) went to the public library at least once a week to load up on books. My mom and grandma did that until they died. My mom enjoyed historical novels (really thick ones especially). My grandma enjoyed biographies and art books. I learned a lot about various artists from browsing thru her library books when I would visit her. Neither one of them ever had a computer.
My dad was an electrical engineer for Bell Labs, Lockheed, NASA, NAVAIRSYSCOM, and NARF San Diego. He held several patents, and made money off of them. He worked on the X-15 and Gemini projects in the 1950's-60's. He didn't
own a computer but he
developed computer systems for all the above.
He made good use of the library when he attended University of Florida college of engineering for his bachelor's degree.
My high school friends and I used to go to the library together, and actually look at books and magazines there!
One year, when I was in high school, I entered a magazine contest that required a research essay to enter. I used the library for my research. I didn't win the top prize but I won a one-year free subscription to the magazine. (It was Soviet Life magazine--but that's another story from my past, ha, ha.)
Oh, well. I guess I'm showing my age.
