Simply put and easy to agree with. This is good basics on censorship and also how libraries run. I liked it but near the end it did get a little too political, for a book that is all about being neutral and serving all beliefs in a community. 
It's definitely important to think about these topics but I'm pretty sure that everyone who would read this book would also generally agree with the stances taken. The people that need the messages in this book probably wouldn't read it.
