Maybe Lakewood is an exception to the rule? I'm not sure, but yeah, you're right, most if not all schools have some little library in the facilities. When I was in elementary school, we had a small and basic little library (books, no computers); in middle school, we had a slightly larger library that also doubled as a computer lab; and the four weeks I was in public high school, I would usually goof off in the library after I finished lunch and before we had to go back to class.
However, I've NEVER seen a library IRL quite like Elwood City's, like you said, that place is massive and two stories high, but then again, I wonder if it's their ONLY library in the entire town? My town has a number of small branch libraries, but Elwood does seem more like a small town, so I'm guessing maybe it's their only one.
