Literature does not have to be fluff. One of the best non-fiction books I've read that's both informative and has beautiful writing is, "On Immunity: An Inoculation " by Eula Biss. It's both informative and a pleasure to read.
I’m pretty sure The New Yorker thinks that. It’s called “literature”, and a lot of it is pretty good. Sounds like you’ll want to stay away from Russian authors, though.
By analogy, you can drive to the top of Mt. Washington, but people still hike it. Either way will deliver the view from top, but each will be a distinct experience.
