Library Rules

One day my uncle told me about some library rules. He told me that there we have to keep silent. If we or anyone needed something then we have to whisper and he also told me that if we have to take some book to home we have to return on time. Otherwise, there may be charges. In the library there are so many books in there, general knowledge books are also there. There are math, science, social studies,poem and many more books are there. He told me that.
