library book labels

This year I'm using 2"x4" labels for all the books I either beg, borrow, or buy for my classroom.  Since I'm in 4th grade it doesn't seem I buy as many as I use to when it involved picture books.

Hopefully the bigger labels will remind students where the book belongs once the book is finished.

Here is a picture of my library...as you can see, I don't have room for too many more books.
