Hello! I know I want to organize my library by genre/topic, but should I also have my books leveled? If so, what's a good way to do that? I'm hoping to acquire a great deal of books for my library by the beginning of the school year, but do I need to go through and level them all? How does that work? How can I make sure that students are able to find books on their "just right" reading level independently? Thanks for any guidance you can provide!
