I can't relate. They had a paragraph or two on almost anything. Sure that was not much but it was enough as a starting point for figuring out if you wanted to know more.

You didn't need to be in libraries all day. Depends how much research you wanted to do or how in depth your question were. For many first glances in some topic it was enough to look at your local book store and maybe get an introductory book on the topic (or borrow that book from a library).

Sure, things were slower back then, on the other side, people had more time to actually read the stuff and also the stamina to do so and not stayed totally on the surface as 2 min later they were already onto something else. Upsides and downsides.

The internet has been a great enabler for people with the stamina and interest to actually really educate themselves but many are just floating on slop and information trash nowadays, learning nothing.
