As a librarian I find it hard to classify a library, because each is very different. This book has been updated for a modern library, and while it tries to stay simple for the reader, it touches on things not all libraries have, as well as skipping things. Plus the way it reads makes it sound like every library has those things, when they don’t. Not all libraries have 3D Printers or robot clubs. Some are barely able to provide story time. And the picture they provide is more school set, than public set.
