Thing 13 - Tagging

I love tagging items so the can be found easily. I do this all the time in my online catalog. I create lists of books that I know I am going to have to pull again for a teacher/ grade level/ or project. I would love to be able to "tag" a book with a teacher's name/ lesson idea, etc for others to see and to be able to easily pull it up. Our librarians could really network indistrict if we could tag a book with a grade level and teaching concept. It would make lesson planning SO easy!
