I created a set of library labels that you can use to organize your classroom library. Each genre or topic helps you group your books, as well as help you find holes in your collection. I added labels for leveled books (based on Fountas and Pinnell) as well.
The labels are made for business card labels found in all major stationery stores.
I love incorporating "just right" books through leveled sets, as well as different topics. It helps my students choose books more meaningfully and engage in topics that interest them.
