Library Lion, by Michelle Knudsen, is the perfect story to introduce manners of the library to your students. This book's Lexile reading level is 470L, and it would be of the greatest benefit to preschoolers or kindergartners. The central focus of the story is on this lion who ventures into the library one day. The librarian, Miss Merriweather, is strict when it comes to following the rules in the library. When the lion wanders in, most people are panicking about the fact that a lion is walking around. Miss Merriweather tells everyone that he is only allowed to stay as long as he follows the rules. The library must be quiet at all times, and there is no running allowed. The lion proves to be of big help to the librarian and all of the people working there. His big feet are surprisingly quiet on the library floor, and he loves to be a comfy backrest for all of the children who come for story hour. He always makes sure that he is following the rules, but one day an emergency happens. Readers must ask themselves: are there good reasons to sometimes break the rules? This story would be perfect to read to preschoolers or kindergartners who have never been to the library before. It shows the rules that most libraries require students to follow, but it also helps them see that sometimes it is okay to break those rules when emergencies happen. I would read this book to my students before they took a trip to the library during the first few days of school. We could talk about the rules and mannerisms of the library, and then we could all take a class field trip to explore it together!
