Furthermore, public libraries are not necessarily free. In America they virtually are all; fees only for late returns. But this is not globally true; in some parts of the world, libraries open to the public charge a fee for checking out books, or even require a fee for entry.

People tend to call their personal library a "book collection" or the like, but it's a library, in just the same way that a Little Free Library is.

So most people who read have at least a small private library, whether they think of it in those terms or not.
