Are you looking for classroom library labels for your book bins and book return? These labels are great for leveling books and organizing them by theme. I like to have a variety of baskets in my room to allow students to search by theme or level so both are included. There are also a few editable options to add your own themes with a matching look. 
 
Included:
"Let's Read" Library Sign (Color and Ink Saving Option)
Levels A-Z Variety of Designs
A Variety of Themes/Genres with Pictures
Book Return Label
Book Hospital Label
