Harry librarian poetry

So I guess it is National Library Week. Who knew? Well, the folks at Buzzfeed. And they have provided an assortment of passive aggressive library signs to mark the occasion. This particular one is quite poetic. It's not the best one, mind you, but it's the only one that pays attention to rhyme and meter. Also from what I can gather it's a take on something from Harry Potter. Which may or may not be a strike against it depending on your feelings toward said Potter.
