Actually the primary purpose of a library is to be a repository of books, not a reading room. Just like the primary purpose of a bookstore is to sell books, a library is a place to check out books.

Besides libraries should change! Who the heck goes to a library to look at encyclopedias to write papers anymore? If you are doing academic research, go to an academic library — a place where you’ll find few kids. But a community library? That should be a place where everyone is welcome and excited about books, not a coworking space for old curmudgeons. If you want a perfectly silent reading environment — go to your home.
