Dust Cover Dilemma?

I take the dust covers off of my books that are in the classroom library so I have accummulated a huge stack of them in a cupboard.  I was setting up my Focus Board for our new unit and I decided to use the book jackets to enhance the board. Since we are starting biography book clubs and studying nonfiction narrative books, I chose books suited to those two areas.

I hot glued them onto a map holder that is above the board.
