I have limited space in my classroom and am trying to figure out how to organize and consolidate the two. I have an effective organizational system for the older paperbacks (blue crates). Books in the crate (and on the poster - which my students utilize) are organized by level and Lexile. The newer one seems to lack that organization, both in the crates and on the poster. Any suggestions on how to organize/consolidate the two in a way that is most user-friendly for students?
