Searching for an image in Bing.com, I looked up "pre-kindergarten library" and found this. I chose this image because it shows what an elementary school library could look like. I also liked this image because the school where the image was taken, Ecole Parkside School, says that they include extra student involvement with the library by joining the Library Club where "Students from grades 4, 5 and 6 are invited to assist in the operation of the library at noon and after school. They shelve books and help to process new acquisitions." A very neat way to get students involved!
