Category Labels for Elementary

So my new obsession is these little category labels with pictures (you can get them from Highsmith or Demco and probably other places - Demco has a better selection of them). I started with labeling my holiday books so that it'd be easier to pull them, but I'm finding it makes it the library so much more user friendly for the elementary kids (and some of the teachers) so I've now labeled poetry, biographies, sports, dinosaurs, and space and am gradually working my way through other highly requested areas. It's kind of relaxing to just sit and do it for an hour, and I am able to weed a little as I go along. I decided to do fiction as well so I can quickly pull a dinosaur or space fiction book. One thing to note is that you do need to buy label protectors or they fall right off and/or get scratched.

Some of the categories I am ordering labels for next:
Animals
Art
Dogs/Cats/Horses
Cars
Crafts
Cooking
Fall/Spring/Summer/Winter
Fairytales/Fables/Mythology
Health
Horror
Technology
Weather
