Is that going outside? How will the books stay dry (out of the rain, and out of the damp)? It looks very good.
I did a similar structure for selling boxes of eggs - ended up attaching slates with construction adhesive, very easy & quick, looks very smart. Someone will have a few spare slates knocking around in good condition.
Flashband is horrible stuff to work with, and looks like a bodge job (even when it's working well). If you have to choose between felt and flashing tape, go with felt. Then change it to slates later
