One day, when my type-A personality gets the best of me, I hope to be this organized:
This amazing teacher has color-coded the book shelves and I can only assume each book has the corresponding sticker on the back or inside cover.
However, this would be hundreds of hours worth of work considering the nine book cases I have in my classroom. So until I get minions, my clustering by novel type will just have to do.
However, if you have any of these laying around, send them my way!
