What makes a good public library: Second argument

Introduction

A library is easy to describe as a building full of books, and easy to defend on that basis until someone points out that most of those books are available elsewhere, often faster. The buildings that thrive anyway are doing something the description misses.

First argument

The first thing a library provides is a place to be that costs nothing. Almost every other indoor space in a town expects you to buy something, and the few that do not are usually closed, or noisy, or somebody's office. A room you can sit in for three hours without spending money is rarer than it sounds.
